Audio settings based on environment

Description

FIELD OF THE DISCLOSURE

The disclosure is related to consumer goods and, more particularly, to methods, systems, products, features, services, and other elements directed to media playback or some aspect thereof.

BACKGROUND

Options for accessing and listening to digital audio in an out-loud setting were limited until in 2003, when SONOS, Inc. filed for one of its first patent applications, entitled “Method for Synchronizing Audio Playback between Multiple Networked Devices,” and began offering a media playback system for sale in 2005. The Sonos Wireless HiFi System enables people to experience music from many sources via one or more networked playback devices. Through a software control application installed on a smartphone, tablet, or computer, one can play what he or she wants in any room that has a networked playback device. Additionally, using the controller, for example, different songs can be streamed to each room with a playback device, rooms can be grouped together for synchronous playback, or the same song can be heard in all rooms synchronously.

Given the ever growing interest in digital media, there continues to be a need to develop consumer-accessible technologies to further enhance the listening experience.

DETAILED DESCRIPTION
I. Overview

Embodiments described herein involve dynamically adjusting the equalization of a playback device based on the environment in which the playback device is operating. While a playback device may be factory configured to perform advantageously in a typical operating environment, the factory configuration may not be ideal for all environments. Therefore, adjusting the equalization of the playback device based on the current operating environment may improve the listening experience for some listeners.

Consider that, as one example, a playback device may be configured to perform advantageously in a small room, but nonetheless may come to be positioned outdoors. When operating outdoors, boosting the bass levels of the playback may result in an improved listening experience for some users. Other such examples may exist as well.

Some audio playback systems implement a manual approach for adjustment of equalization based on environment. Under this approach, a microphone is cabled to a given component of an audio system, such as an amplifier or an audio-video receiver. A user is then expected to position the microphone in a position in which the user would typically listen to the audio system. The given component of the audio system then drives audio output to one or more speakers. Then, the speaker output is detected by the microphone. Playback of the audio component is then adjusted based on the speaker output detected by the microphone.

Such a manual approach has several disadvantages. First, the adjustment process is often overlooked by the user because, for example, the user may be required to initiate the adjustment and position the microphone. Second, the adjustment process requires a separate microphone, which may not be included with any of the components of the audio system. Third, the manual approach does not lend itself to frequent adjustment when one or more of the speakers may be re-positioned in different locations throughout a home or outdoors. Therefore, an improved, dynamic approach to adjustment based on environment is desired.

Described herein are example methods and systems for dynamically adjusting equalization of a playback device based on the environment in which the playback device is operating. An example playback device may include a speaker, a microphone, and a processor. The playback device may emit an audio signal, such as a pulse, from the speaker. As the audio signal propagates, the signal may encounter various objects, such as walls and furniture, throughout the environment. When an object is encountered, the object may variably reflect or absorb portions of the audio signal. For instance, when the audio signal encounters an interior wall, a portion of the audio signal may be reflected by the interior wall. The portion of the audio signal may then encounter other objects that variably reflect or absorb some of the portion in turn. At some point, a portion of the reflected audio signal may reflect back toward the playback device from which the audio signal was emitted. The microphone of the playback device may then detect at least a portion of the reflected audio signal.

In response to detecting the reflected audio signal, the playback device may determine one or more reflection characteristics based on the reflected audio signal. For example, the playback device may determine an amount of time from when the playback device emitted the first audio signal to when the playback device detected the reflected audio signal. The amount of time may indicate the nature of the environment. For instance, a relatively short amount of time may indicate that the playback device is in a small room while a relatively amount of time may indicate that the playback device is in a large room. Alternatively, the playback device may determine the sound pressure level of the second audio signal. A relatively low sound pressure level may indicate that there is relatively more absorptive material in the environment as compared with a relatively higher sound pressure level. Or the relatively low sound pressure level may indicate that the first audio signal travelled a relatively longer distance before reflecting. Other reflection characteristics may exist, as may many other examples of indications regarding the nature of the environment.

The playback device may then adjust an equalization setting of the playback device based on the one or more reflection characteristics. Further, two or more reflection characteristics may be used in combination. For instance, a relatively long amount of time and a relatively low sound pressure level may indicate that the playback device is either presumed to be outside or in a very large room. In either case, the playback device may adjust the equalization setting based on that environment. In the above instance, where the playback device is either outside or in a very large room, the bass frequencies of the playback device may be increased, which may, to some listeners, improve enjoyment of the audio played by the playback device in the more spacious environment. In contrast, where the reflection characteristics indicate that the playback device is in a small room, the bass frequencies of the playback device may be decreased, which may improve enjoyment of the audio played by the playback device in the small room. Once the equalization setting is adjusted, the playback device may then play an audio track according to the equalization setting.

As indicated above, the present application involves dynamically adjusting the equalization of a playback device based on the environment in which the playback device is operating. In one aspect, a method is provided. The method involves emitting, by a playback device, a first audio signal, detecting, by the playback device, a second audio signal, where at least a portion of the second audio signal is a reflection of the first audio signal, in response to the detecting, determining one or more reflection characteristics, where each of the one or more reflection characteristics are based on at least the second audio signal, adjusting an equalization setting of the playback device based on the one or more reflection characteristics; and causing an audio track to play according to the adjusted equalization setting.

In another aspect, a second method is provided. The second method is operable in a media playback system comprising a plurality of playback devices, where each playback device comprises a respective microphone and a respective speaker. The second method involves receiving an indication of a first audio signal, detecting, by a microphone of the first playback device, a second audio signal, where at least a portion of the second audio signal is indicative of the first audio signal, in response to the detecting, determining a first reflection characteristic based on the second audio signal, adjusting an equalization setting of the first playback device based on at least the first reflection characteristic, and sending to a second media playback device an indication of the first reflection characteristic.

In another aspect, a device is provided. The device includes a speaker, a microphone that is physically coupled to the speaker, a processor, a network interface, a data storage, and a program logic stored in the data storage. The program logic is executable by the processor to emit a first audio signal from the speaker, detect, via the microphone, a second audio signal, wherein at least a portion of the second audio signal is a reflection of the first audio signal, in response to the detecting, determine a first reflection characteristic based on at least the second audio signal, adjust an equalization setting of the playback device based on at least the first reflection characteristic, and play, via the speaker, an audio track according to the equalization setting.

In yet another aspect, a non-transitory computer readable memory is provided. The non-transitory computer readable memory has stored thereon instructions executable by a computing device to cause the computing device to perform functions. The functions include emitting, by a playback device, a first audio signal, detecting, by the playback device, a second audio signal, wherein at least a portion of the second audio signal is a reflection of the first audio signal, in response to the detecting, determining one or more reflection characteristics, wherein each of the one or more reflection characteristics are based on at least the second audio signal, adjusting an equalization setting of the playback device based on the one or more reflection characteristics; and causing an audio track to play according to the adjusted equalization setting.

It will be understood by one of ordinary skill in the art that this disclosure includes numerous other embodiments.

II. Example Operating Environment

FIG. 1 shows an example configuration of a media playback system 100 in which one or more embodiments disclosed herein may be practiced or implemented. The media playback system 100 as shown is associated with an example home environment having several rooms and spaces, such as for example, a master bedroom, an office, a dining room, and a living room. As shown in the example of FIG. 1, the media playback system 100 includes playback devices 102-124, control devices 126 and 128, and a wired or wireless network router 130.

Further discussions relating to the different components of the example media playback system 100 and how the different components may interact to provide a user with a media experience may be found in the following sections. While discussions herein may generally refer to the example media playback system 100, technologies described herein are not limited to applications within, among other things, the home environment as shown in FIG. 1. For instance, the technologies described herein may be useful in environments where multi-zone audio may be desired, such as, for example, a commercial setting like a restaurant, mall or airport, a vehicle like a sports utility vehicle (SUV), bus or car, a ship or boat, an airplane, and so on.

a. Example Playback Devices

FIG. 2 shows a functional block diagram of an example playback device 200 that may be configured to be one or more of the playback devices 102-124 of the media playback system 100 of FIG. 1. The playback device 200 may include a processor 202, software components 204, memory 206, audio processing components 208, audio amplifier(s) 210, speaker(s) 212, a network interface 214 including wireless interface(s) 216 and wired interface(s) 218 and a microphone 220. In one case, the playback device 200 may not include the speaker(s) 212, but rather a speaker interface for connecting the playback device 200 to external speakers. In another case, the playback device 200 may include neither the speaker(s) 212 nor the audio amplifier(s) 210, but rather an audio interface for connecting the playback device 200 to an external audio amplifier or audio-visual receiver.

In one example, the processor 202 may be a clock-driven computing component configured to process input data according to instructions stored in the memory 206. The memory 206 may be a tangible computer-readable medium configured to store instructions executable by the processor 202. For instance, the memory 206 may be data storage that can be loaded with one or more of the software components 204 executable by the processor 202 to achieve certain functions. In one example, the functions may involve the playback device 200 retrieving audio data from an audio source or another playback device. In another example, the functions may involve the playback device 200 sending audio data to another device or playback device on a network. In yet another example, the functions may involve pairing of the playback device 200 with one or more playback devices to create a multi-channel audio environment.

Certain functions may involve the playback device 200 synchronizing playback of audio content with one or more other playback devices. During synchronous playback, a listener will preferably not be able to perceive time-delay differences between playback of the audio content by the playback device 200 and the one or more other playback devices. U.S. Pat. No. 8,234,395 entitled, “System and method for synchronizing operations among a plurality of independently clocked digital data processing devices,” which is hereby incorporated by reference, provides in more detail some examples for audio playback synchronization among playback devices.

The memory 206 may further be configured to store data associated with the playback device 200, such as one or more zones and/or zone groups the playback device 200 is a part of, audio sources accessible by the playback device 200, or a playback queue that the playback device 200 (or some other playback device) may be associated with. The data may be stored as one or more state variables that are periodically updated and used to describe the state of the playback device 200. The memory 206 may also include the data associated with the state of the other devices of the media system, and shared from time to time among the devices so that one or more of the devices have the most recent data associated with the system. Other embodiments are also possible.

The audio processing components 208 may include one or more digital-to-analog converters (DAC), an audio preprocessing component, an audio enhancement component or a digital signal processor (DSP), and so on. In one embodiment, one or more of the audio processing components 208 may be a subcomponent of the processor 202. In one example, audio content may be processed and/or intentionally altered by the audio processing components 208 to produce audio signals. The produced audio signals may then be provided to the audio amplifier(s) 210 for amplification and playback through speaker(s) 212. Particularly, the audio amplifier(s) 210 may include devices configured to amplify audio signals to a level for driving one or more of the speakers 212. The speaker(s) 212 may include an individual transducer (e.g., a “driver”) or a complete speaker system involving an enclosure with one or more drivers. A particular driver of the speaker(s) 212 may include, for example, a subwoofer (e.g., for low frequencies), a mid-range driver (e.g., for middle frequencies), and/or a tweeter (e.g., for high frequencies). In some cases, each transducer in the one or more speakers 212 may be driven by an individual corresponding audio amplifier of the audio amplifier(s) 210. In addition to producing analog signals for playback by the playback device 200, the audio processing components 208 may be configured to process audio content to be sent to one or more other playback devices for playback.

Audio content to be processed and/or played back by the playback device 200 may be received from an external source, such as via an audio line-in input connection (e.g., an auto-detecting 3.5 mm audio line-in connection) or the network interface 214.

The network interface 214 may be configured to facilitate a data flow between the playback device 200 and one or more other devices on a data network. As such, the playback device 200 may be configured to receive audio content over the data network from one or more other playback devices in communication with the playback device 200, network devices within a local area network, or audio content sources over a wide area network such as the Internet. In one example, the audio content and other signals transmitted and received by the playback device 200 may be transmitted in the form of digital packet data containing an Internet Protocol (IP)-based source address and IP-based destination addresses. In such a case, the network interface 214 may be configured to parse the digital packet data such that the data destined for the playback device 200 is properly received and processed by the playback device 200.

As shown, the network interface 214 may include wireless interface(s) 216 and wired interface(s) 218. The wireless interface(s) 216 may provide network interface functions for the playback device 200 to wirelessly communicate with other devices (e.g., other playback device(s), speaker(s), receiver(s), network device(s), control device(s) within a data network the playback device 200 is associated with) in accordance with a communication protocol (e.g., any wireless standard including IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4G mobile communication standard, and so on). The wired interface(s) 218 may provide network interface functions for the playback device 200 to communicate over a wired connection with other devices in accordance with a communication protocol (e.g., IEEE 802.3). While the network interface 214 shown in FIG. 2 includes both wireless interface(s) 216 and wired interface(s) 218, the network interface 214 may in some embodiments include only wireless interface(s) or only wired interface(s).

The microphone 220 may be arranged to detect sound in the environment of the playback device 200. For instance, the microphone may be mounted on an exterior wall of a housing of the playback device. The microphone may be any type of microphone now known or later developed such as a condenser microphone, electret condenser microphone, or a dynamic microphone. The microphone may be sensitive to a portion of the frequency range of the speaker(s) 220. One or more of the speaker(s) 220 may operate in reverse as the microphone 220.

In one example, the playback device 200 and one other playback device may be paired to play two separate audio components of audio content. For instance, playback device 200 may be configured to play a left channel audio component, while the other playback device may be configured to play a right channel audio component, thereby producing or enhancing a stereo effect of the audio content. The paired playback devices (also referred to as “bonded playback devices”) may further play audio content in synchrony with other playback devices.

In another example, the playback device 200 may be sonically consolidated with one or more other playback devices to form a single, consolidated playback device. A consolidated playback device may be configured to process and reproduce sound differently than an unconsolidated playback device or playback devices that are paired, because a consolidated playback device may have additional speaker drivers through which audio content may be rendered. For instance, if the playback device 200 is a playback device designed to render low frequency range audio content (i.e. a subwoofer), the playback device 200 may be consolidated with a playback device designed to render full frequency range audio content. In such a case, the full frequency range playback device, when consolidated with the low frequency playback device 200, may be configured to render only the mid and high frequency components of audio content, while the low frequency range playback device 200 renders the low frequency component of the audio content. The consolidated playback device may further be paired with a single playback device or yet another consolidated playback device.

By way of illustration, SONOS, Inc. presently offers (or has offered) for sale certain playback devices including a “PLAY:1,” “PLAY:3,” “PLAY:5,” “PLAYBAR,” “CONNECT:AMP,” “CONNECT,” and “SUB.” Any other past, present, and/or future playback devices may additionally or alternatively be used to implement the playback devices of example embodiments disclosed herein. Additionally, it is understood that a playback device is not limited to the example illustrated in FIG. 2 or to the SONOS product offerings. For example, a playback device may include a wired or wireless headphone. In another example, a playback device may include or interact with a docking station for personal mobile media playback devices. In yet another example, a playback device may be integral to another device or component such as a television, a lighting fixture, or some other device for indoor or outdoor use.

b. Example Playback Zone Configurations

Referring back to the media playback system 100 of FIG. 1, the environment may have one or more playback zones, each with one or more playback devices. The media playback system 100 may be established with one or more playback zones, after which one or more zones may be added, or removed to arrive at the example configuration shown in FIG. 1. Each zone may be given a name according to a different room or space such as an office, bathroom, master bedroom, bedroom, kitchen, dining room, living room, and/or balcony. In one case, a single playback zone may include multiple rooms or spaces. In another case, a single room or space may include multiple playback zones.

As shown in FIG. 1, the balcony, dining room, kitchen, bathroom, office, and bedroom zones each have one playback device, while the living room and master bedroom zones each have multiple playback devices. In the living room zone, playback devices 104, 106, 108, and 110 may be configured to play audio content in synchrony as individual playback devices, as one or more bonded playback devices, as one or more consolidated playback devices, or any combination thereof. Similarly, in the case of the master bedroom, playback devices 122 and 124 may be configured to play audio content in synchrony as individual playback devices, as a bonded playback device, or as a consolidated playback device.

In one example, one or more playback zones in the environment of FIG. 1 may each be playing different audio content. For instance, the user may be grilling in the balcony zone and listening to hip hop music being played by the playback device 102 while another user may be preparing food in the kitchen zone and listening to classical music being played by the playback device 114. In another example, a playback zone may play the same audio content in synchrony with another playback zone. For instance, the user may be in the office zone where the playback device 118 is playing the same rock music that is being playing by playback device 102 in the balcony zone. In such a case, playback devices 102 and 118 may be playing the rock music in synchrony such that the user may seamlessly (or at least substantially seamlessly) enjoy the audio content that is being played out-loud while moving between different playback zones. Synchronization among playback zones may be achieved in a manner similar to that of synchronization among playback devices, as described in previously referenced U.S. Pat. No. 8,234,395.

As suggested above, the zone configurations of the media playback system 100 may be dynamically modified, and in some embodiments, the media playback system 100 supports numerous configurations. For instance, if a user physically moves one or more playback devices to or from a zone, the media playback system 100 may be reconfigured to accommodate the change(s). For instance, if the user physically moves the playback device 102 from the balcony zone to the office zone, the office zone may now include both the playback device 118 and the playback device 102. The playback device 102 may be paired or grouped with the office zone and/or renamed if so desired via a control device such as the control devices 126 and 128. On the other hand, if the one or more playback devices are moved to a particular area in the home environment that is not already a playback zone, a new playback zone may be created for the particular area.

Further, different playback zones of the media playback system 100 may be dynamically combined into zone groups or split up into individual playback zones. For instance, the dining room zone and the kitchen zone 114 may be combined into a zone group for a dinner party such that playback devices 112 and 114 may render audio content in synchrony. On the other hand, the living room zone may be split into a television zone including playback device 104, and a listening zone including playback devices 106, 108, and 110, if the user wishes to listen to music in the living room space while another user wishes to watch television.

c. Example Control Devices

FIG. 3 shows a functional block diagram of an example control device 300 that may be configured to be one or both of the control devices 126 and 128 of the media playback system 100. As shown, the control device 300 may include a processor 302, memory 304, a network interface 306, and a user interface 308. In one example, the control device 300 may be a dedicated controller for the media playback system 100. In another example, the control device 300 may be a network device on which media playback system controller application software may be installed, such as for example, an iPhone™, iPad™ or any other smart phone, tablet or network device (e.g., a networked computer such as a PC or Mac™).

The processor 302 may be configured to perform functions relevant to facilitating user access, control, and configuration of the media playback system 100. The memory 304 may be configured to store instructions executable by the processor 302 to perform those functions. The memory 304 may also be configured to store the media playback system controller application software and other data associated with the media playback system 100 and the user.

In one example, the network interface 306 may be based on an industry standard (e.g., infrared, radio, wired standards including IEEE 802.3, wireless standards including IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4G mobile communication standard, and so on). The network interface 306 may provide a means for the control device 300 to communicate with other devices in the media playback system 100. In one example, data and information (e.g., such as a state variable) may be communicated between control device 300 and other devices via the network interface 306. For instance, playback zone and zone group configurations in the media playback system 100 may be received by the control device 300 from a playback device or another network device, or transmitted by the control device 300 to another playback device or network device via the network interface 306. In some cases, the other network device may be another control device.

Playback device control commands such as volume control and audio playback control may also be communicated from the control device 300 to a playback device via the network interface 306. As suggested above, changes to configurations of the media playback system 100 may also be performed by a user using the control device 300. The configuration changes may include adding/removing one or more playback devices to/from a zone, adding/removing one or more zones to/from a zone group, forming a bonded or consolidated player, separating one or more playback devices from a bonded or consolidated player, among others. Accordingly, the control device 300 may sometimes be referred to as a controller, whether the control device 300 is a dedicated controller or a network device on which media playback system controller application software is installed.

The user interface 308 of the control device 300 may be configured to facilitate user access and control of the media playback system 100, by providing a controller interface such as the controller interface 400 shown in FIG. 4. The controller interface 400 includes a playback control region 410, a playback zone region 420, a playback status region 430, a playback queue region 440, and an audio content sources region 450. The user interface 400 as shown is just one example of a user interface that may be provided on a network device such as the control device 300 of FIG. 3 (and/or the control devices 126 and 128 of FIG. 1) and accessed by users to control a media playback system such as the media playback system 100. Other user interfaces of varying formats, styles, and interactive sequences may alternatively be implemented on one or more network devices to provide comparable control access to a media playback system.

The playback control region 410 may include selectable (e.g., by way of touch or by using a cursor) icons to cause playback devices in a selected playback zone or zone group to play or pause, fast forward, rewind, skip to next, skip to previous, enter/exit shuffle mode, enter/exit repeat mode, enter/exit cross fade mode. The playback control region 410 may also include selectable icons to modify equalization settings, and playback volume, among other possibilities.

The playback zone region 420 may include representations of playback zones within the media playback system 100. In some embodiments, the graphical representations of playback zones may be selectable to bring up additional selectable icons to manage or configure the playback zones in the media playback system, such as a creation of bonded zones, creation of zone groups, separation of zone groups, and renaming of zone groups, among other possibilities.

For example, as shown, a “group” icon may be provided within each of the graphical representations of playback zones. The “group” icon provided within a graphical representation of a particular zone may be selectable to bring up options to select one or more other zones in the media playback system to be grouped with the particular zone. Once grouped, playback devices in the zones that have been grouped with the particular zone will be configured to play audio content in synchrony with the playback device(s) in the particular zone. Analogously, a “group” icon may be provided within a graphical representation of a zone group. In this case, the “group” icon may be selectable to bring up options to deselect one or more zones in the zone group to be removed from the zone group. Other interactions and implementations for grouping and ungrouping zones via a user interface such as the user interface 400 are also possible. The representations of playback zones in the playback zone region 420 may be dynamically updated as playback zone or zone group configurations are modified.

The playback status region 430 may include graphical representations of audio content that is presently being played, previously played, or scheduled to play next in the selected playback zone or zone group. The selected playback zone or zone group may be visually distinguished on the user interface, such as within the playback zone region 420 and/or the playback status region 430. The graphical representations may include track title, artist name, album name, album year, track length, and other relevant information that may be useful for the user to know when controlling the media playback system via the user interface 400.

The playback queue region 440 may include graphical representations of audio content in a playback queue associated with the selected playback zone or zone group. In some embodiments, each playback zone or zone group may be associated with a playback queue containing information corresponding to zero or more audio items for playback by the playback zone or zone group. For instance, each audio item in the playback queue may comprise a uniform resource identifier (URI), a uniform resource locator (URL) or some other identifier that may be used by a playback device in the playback zone or zone group to find and/or retrieve the audio item from a local audio content source or a networked audio content source, possibly for playback by the playback device.

In one example, a playlist may be added to a playback queue, in which case information corresponding to each audio item in the playlist may be added to the playback queue. In another example, audio items in a playback queue may be saved as a playlist. In a further example, a playback queue may be empty, or populated but “not in use” when the playback zone or zone group is playing continuously streaming audio content, such as Internet radio that may continue to play until otherwise stopped, rather than discrete audio items that have playback durations. In an alternative embodiment, a playback queue can include Internet radio and/or other streaming audio content items and be “in use” when the playback zone or zone group is playing those items. Other examples are also possible.

When playback zones or zone groups are “grouped” or “ungrouped,” playback queues associated with the affected playback zones or zone groups may be cleared or re-associated. For example, if a first playback zone including a first playback queue is grouped with a second playback zone including a second playback queue, the established zone group may have an associated playback queue that is initially empty, that contains audio items from the first playback queue (such as if the second playback zone was added to the first playback zone), that contains audio items from the second playback queue (such as if the first playback zone was added to the second playback zone), or a combination of audio items from both the first and second playback queues. Subsequently, if the established zone group is ungrouped, the resulting first playback zone may be re-associated with the previous first playback queue, or be associated with a new playback queue that is empty or contains audio items from the playback queue associated with the established zone group before the established zone group was ungrouped. Similarly, the resulting second playback zone may be re-associated with the previous second playback queue, or be associated with a new playback queue that is empty, or contains audio items from the playback queue associated with the established zone group before the established zone group was ungrouped. Other examples are also possible.

Referring back to the user interface 400 of FIG. 4, the graphical representations of audio content in the playback queue region 440 may include track titles, artist names, track lengths, and other relevant information associated with the audio content in the playback queue. In one example, graphical representations of audio content may be selectable to bring up additional selectable icons to manage and/or manipulate the playback queue and/or audio content represented in the playback queue. For instance, a represented audio content may be removed from the playback queue, moved to a different position within the playback queue, or selected to be played immediately, or after any currently playing audio content, among other possibilities. A playback queue associated with a playback zone or zone group may be stored in a memory on one or more playback devices in the playback zone or zone group, on a playback device that is not in the playback zone or zone group, and/or some other designated device.

The audio content sources region 450 may include graphical representations of selectable audio content sources from which audio content may be retrieved and played by the selected playback zone or zone group. Discussions pertaining to audio content sources may be found in the following section.

As indicated previously, one or more playback devices in a zone or zone group may be configured to retrieve for playback audio content (e.g. according to a corresponding URI or URL for the audio content) from a variety of available audio content sources. In one example, audio content may be retrieved by a playback device directly from a corresponding audio content source (e.g., a line-in connection). In another example, audio content may be provided to a playback device over a network via one or more other playback devices or network devices.

Example audio content sources may include a memory of one or more playback devices in a media playback system such as the media playback system 100 of FIG. 1, local music libraries on one or more network devices (such as a control device, a network-enabled personal computer, or a networked-attached storage (NAS), for example), streaming audio services providing audio content via the Internet (e.g., the cloud), or audio sources connected to the media playback system via a line-in input connection on a playback device or network devise, among other possibilities.

In some embodiments, audio content sources may be regularly added or removed from a media playback system such as the media playback system 100 of FIG. 1. In one example, an indexing of audio items may be performed whenever one or more audio content sources are added, removed or updated. Indexing of audio items may involve scanning for identifiable audio items in all folders/directory shared over a network accessible by playback devices in the media playback system, and generating or updating an audio content database containing metadata (e.g., title, artist, album, track length, among others) and other associated information, such as a URI or URL for each identifiable audio item found. Other examples for managing and maintaining audio content sources may also be possible.

The above discussions relating to playback devices, controller devices, playback zone configurations, and media content sources provide only some examples of operating environments within which functions and methods described below may be implemented. Other operating environments and configurations of media playback systems, playback devices, and network devices not explicitly described herein may also be applicable and suitable for implementation of the functions and methods.

III. Example Method for Adjusting Equalization Based on Environment

As discussed above, embodiments described herein may involve dynamically adjusting the equalization of a playback device based on the environment in which the playback device is operating.

Method 500 shown in FIG. 5 presents an embodiment of a method that can be implemented within an operating environment involving, for example, the media playback system 100 of FIG. 1, one or more of the playback device 200 of FIG. 2, and one or more of the control device 300 of FIG. 3. Method 500 may include one or more operations, functions, or actions as illustrated by one or more of blocks 502-510. Although the blocks are illustrated in sequential order, these blocks may also be performed in parallel, and/or in a different order than those described herein. Also, the various blocks may be combined into fewer blocks, divided into additional blocks, and/or removed based upon the desired implementation.

In addition, for the method 500 and other processes and methods disclosed herein, the flowchart shows functionality and operation of one possible implementation of present embodiments. In this regard, each block may represent a module, a segment, or a portion of program code, which includes one or more instructions executable by a processor for implementing specific logical functions or steps in the process. The program code may be stored on any type of computer readable medium, for example, such as a storage device including a disk or hard drive. The computer readable medium may include non-transitory computer readable medium, for example, such as computer-readable media that stores data for short periods of time like register memory, processor cache and Random Access Memory (RAM). The computer readable medium may also include non-transitory media, such as secondary or persistent long term storage, like read only memory (ROM), optical or magnetic disks, compact-disc read only memory (CD-ROM), for example. The computer readable media may also be any other volatile or non-volatile storage systems. The computer readable medium may be considered a computer readable storage medium, for example, or a tangible storage device. In addition, for the method 500 and other processes and methods disclosed herein, each block in FIG. 5 may represent circuitry that is wired to perform the specific logical functions in the process.

a. Emitting a First Audio Signal from a Playback Device.

At block 502, the playback device emits a first audio signal from the playback device. For instance, playback device 200 of FIG. 2 may output the first audio signal from speaker(s) 212.

The first audio signal may take a variety of different forms. For instance, the first audio signal may include a pulse. Such a pulse may be a recording of a brief audio pulse that approximates an audio impulse signal. Some examples include recordings of an electric spark, a starter pistol shot, or the bursting of a balloon. In some examples, the first audio signal may include a signal that varies over frequency, such as a logarithmic chirp, a sine sweep, a pink noise signal, or a maximum length sequence. Such signals may be chosen for relatively broader-range coverage of the frequency spectrum or for other reasons. The first audio signal may involve other types of audio signals as well.

The first audio signal may have a particular waveform. For instance, the waveform may correspond to any of these example audio signals described above, such as, an electric spark, a starter pistol shot, or the bursting of a balloon. Such a waveform may be represented digitally, such as in an array of data points (i.e. samples) representing the changes in sound pressure over time. The waveform of the first audio signal may be referred to as the first waveform.

The playback device may store the first audio signal as a recording. Then, when emitting the first audio signal, the playback device may playback the recording. The recording may take a variety of audio file formats, such as a waveform audio file format (WAV) or an MPEG-2 audio layer III (MP3), among other examples.

Alternatively, the playback device may dynamically generate the first audio signal. For instance, the playback device may generate a signal that varies over frequency according to a mathematical equation. Other examples are possible as well.

The playback device may emit the first audio signal at a particular sound pressure level (i.e. magnitude). The particular sound pressure level may reflect the peak magnitude of the first audio signal. For instance, the playback device may emit a pulse signal having a peak magnitude of 60 dB (with reference to 20 μPa). The sound pressure level may be configurable. For instance, user input to playback device 200 (or a controller thereof, such as network device 300) may configure the sound pressure of the first audio signal at a particular sound pressure level. Alternatively, the sound pressure level may be pre-determined.

The playback device may emit the first audio signal in response to a trigger. Further, the trigger may cause the playback device to carry out additional functions of the present method. For instance, user input to playback device 200 (or a controller thereof, such as network device 300) may trigger playback device 200 to carry out the present method to adjust the equalization of the playback device. As another example, movement of the playback device (i.e. a change of positioning or in location) may trigger the playback device 200 to carry out the present method. The playback device may detect such a movement via an accelerometer. Other types of triggers are possible as well.

As described above, the playback device may be arranged as part of a media playback system that may include a plurality of playback devices. Each playback device of the media playback system may emit a respective first audio signal. Further, each playback device may perform one or more of the functions described below. For instance, each playback device may emit a respective first audio signal, detect a respective second audio signal, determine one or more respective reflection characteristics, adjust an equalization setting, and cause an audio track to play.

In one instance, a media playback system may include a first playback device and a second playback device. The first playback device may emit the first audio signal and then detect the second audio signal (as discussed below). In addition, the second playback device may emit a third audio signal. The third audio signal may take a variety of forms, including, for instance, any of the example audio signals described above in relation to the first audio signal. In some embodiments, the second playback device may emit the third audio signal in response to receiving an instruction, from the first playback device, to emit the third audio signal. Alternatively, the second playback device may receive the instruction from a controller. Other examples are possible as well.

b. Detecting, by the Playback Device, a Second Audio Signal.

At block 504, the playback device detects, by a microphone, a second audio signal. A portion of the second audio signal may be a reflection of the first audio signal. For instance, playback device 200 may emit the first audio signal, the first audio signal may reflect off of one or more objects (collectively these reflections may be referred to as reverberation), and microphone 220 may detect these reflections as the second audio signal. Another portion of the second audio signal may be a direct propagation of the first audio signal.

The microphone may be communicatively coupled to the processor. For instance, microphone 220 may be coupled to an analog input of processor 202 of playback device 200. Alternatively, microphone 220 may be coupled to an analog-to-digital converter that is coupled, in turn, to processor 202. Other arrangements are possible as well.

Detecting the second audio signal may involve recording the second audio signal. For instance, processor 202 may record the second audio signal and then store the second audio signal in memory 206. Processor 202 may begin recording when the speaker emits the first audio signal. Alternatively, processor 202 may begin recording before or after the speaker emits the first audio signal such that reflections of the first audio signal may be detected by the microphone. The recording may be represented digitally, such as in an array of data points (i.e. samples) representing the changes in sound pressure over time. Further, the second audio signal may have a waveform that may be referred to as the second waveform.

In some circumstances, the second audio signal may include environmental noise. In some circumstances, significant environmental noise within the second audio signal may interfere with or otherwise affect determining the one or more reflection characteristics. For instance, environmental noise may mask or degrade the first audio signal, which may cause the playback device to determine one or more reflection characteristics that may not accurately reflect the environment because of the degradation caused by the environmental noise. Further, in some circumstances, an aspect of the environmental noise may be incorrectly detected as the first audio signal. While the second audio signal may include, as one portion, some background noise, the intention is that at least a portion of the second audio signal is the reflection of the first audio signal.

Accordingly, to reduce the possible effects of environmental noise, detecting the second audio signal may involve determining that the portion of the second audio signal is the reflection of the first audio signal based on the first waveform and the second waveform. For instance, the processor 202 may determine a difference between the first waveform and the second waveform by comparing the two waveforms. The playback device may then determine that the difference is less than a threshold which may indicate that the portion of the second audio signal is the reflection of the first audio signal. The threshold may be set such that a particular degree of similarity between the first waveform and the second waveform indicates that the portion of the second audio signal is a reflection of the first audio signal. Alternatively, several characteristics of the first waveform, such as the magnitude and duration, may be predetermined. The playback device may determine the same characteristics of the second waveform and compare the characteristics to determine that the portion of the second audio signal is the reflection of the first audio signal. As another example, the playback device may perform a deconvolution determination using the first audio signal and the second audio signal. Some embodiments may involve repeating the process described herein to reduce any effect caused by noise in a particular iteration.

The processor may determine the sound pressure level (i.e. magnitude) of the second audio signal. The sound pressure level of the second audio signal may be determined at each point along the waveform of the second audio signal or the sound pressure level may be determined at a subset of points, such as at the point having peak magnitude. For instance, the processor may determine that the second audio signal ha peak magnitude of 50 dB.

In some embodiments, the speaker and microphone may be physically coupled. For instance, a housing may contain both the speaker and the microphone. Further, the housing may additionally contain one or more other components of the playback device, such as a processor, a memory, a network interface, an audio amplifier(s), and/or various audio processing components. Therefore, in one embodiment, playback device 200 may include, within the same housing, processor 202, software components 204, memory 206, audio processing components 208, audio amplifier(s) 210, speaker(s) 212, a network interface 214 including wireless interface(s) 216 and wired interface(s) 218 and a microphone 220. The housing may be a speaker cabinet. Other arrangements are possible as well.

As noted above, in some embodiments, the playback device may be arranged as part of a media playback system that includes two or more playback devices. In such embodiments, the playback device may detect audio signals emitted by other playback devices (as an alternative to or in addition to detecting the second audio signal). Referring to the example media playback system above that includes the first playback device and the second playback device, after the second playback device emits a third audio signal, the first playback device may detect the third audio signal and/or reflections thereof as a fourth audio signal. In some embodiments, the first playback device may then determine that at least a portion of the fourth audio signal is the third audio signal (or a reflection thereof) using, for example, any of the techniques described above.

Detecting audio signals emitted by other playback devices may include functions similar to those of detecting the second audio signal. Further, devices within the media playback system may exchange messages to coordinate the functions described herein. For instance, as noted above, a first playback device may trigger a second playback device to emit a third audio signal. As another example, the second playback device may send an indication of the third audio signal to the first playback device. The indication may assist the first playback device in determining that a portion of the fourth audio signal is the third audio signal (or a reflection thereof), for example. Alternatively, receiving the indication may trigger the first playback device to start listening for an audio signal from the second playback device.

In some embodiments, the first media playback may detect a plurality of audio signals. For instance, the plurality of audio signals may include a reflection of a signal emitted by the first playback device. The plurality of audio signals may also include signals (or reflections thereof) emitted by other playback devices within the media playback system. Other examples are possible as well.

c. Determining One or More Reflection Characteristics.

At block 506, the playback device determines one or more reflection characteristics. Each of the one or more reflection characteristics may indicate an aspect of the environment surrounding the playback device. For instance, one reflection characteristic may indicate that the playback device is inside, or that the playback device is outside. The reflection characteristic may also indicate a relative size of the room that the playback device is currently located within. Another reflection characteristic may indicate the amount of sound absorbing material in the environment. A third reflection characteristic may indicate one or more resonant frequencies of the environment. Many examples are possible.

In some embodiments, each of the one or more reflection characteristics may be based on at least the second audio signal. For instance, the processor 202 may determine one or more reflection characteristics based on the recording of the second audio signal. The one or more reflection characteristics may be further based on the first audio signal such as in a comparison of the second audio signal to the first audio signal.

One of the one or more reflection characteristics may be an amount of time elapsed from emitting the first audio signal to detecting the second audio signal. For instance, the processor 202 may assign to the first audio signal a first timestamp at the time of emitting the first audio signal and may further assign to the second audio signal a second time stamp at the time of detecting the second audio signal. The processor 202 may then determine a difference between the second time stamp and the first time stamp. Since each of the first audio signal and the second audio signal may be emitted and detected, respectively, over a duration of time, the time stamp may be assigned to a particular point in each of the first audio signal and the second audio signal. For instance, the time stamp may be assigned to the respective peaks of the first and second audio signals.

The reflection characteristic may be a qualitative characteristic. For instance, the qualitative characteristic may describe different types of operating environments, such as a “small room,” a “large room,” or “outdoors.” The qualitative characteristic may be based upon a quantitative value, such as an amount of time elapsed from emitting the first signal to detecting the second audio signal. For example, the playback device may determine the qualitative characteristic (e.g. “small room,” “large room,” or “outdoors”) based on a range of values for the amount of time elapsed from emitting the first signal. For example, an amount of time elapsed from emitting the first signal to detecting the second audio signal of 15-20 milliseconds (ms) may indicate a “small room,” 20-30 ms may indicate a “large room,” and an amount of time greater than 30 ms may indicate “outdoors.”

The qualitative characteristics may describe additional features of the room. For instance, the qualitative characteristic may describe a number of objects within the room. Alternatively, the qualitative characteristic may further describe the shape of the room. For example, a qualitative characteristic may indicate “high ceilings” in a “small room” or that the room is relatively much longer than it is wide (i.e. the room is long and narrow).

One or more of the reflection characteristics may relate to a frequency response of a system that includes the playback device and the environment surrounding the playback device. Such a frequency response may be determined based on the emitted first audio signal and detected second audio signal. In particular, the first audio signal (i.e. the stimulus) may excite the system. The detected second audio signal then represents the response of the system in the time domain. The playback device may then determine the frequency response by transforming the time domain response to the frequency domain, such as by determining a Laplace transform on the second audio signal, or the portion thereof that is a reflection of the first audio signal. In some embodiments, determining the Laplace transform may involve determining, by the processor 202, a fast Fourier transform (FFT), such as when the second audio signal is represented as discrete data points. While the FFT is provided by way of example, alternative transformations, such as a Hilbert transform, may be determined as well.

The determined frequency response of the system may indicate aspects of the environment. For instance, the processor 202 may determine that the bass frequencies within the frequency response are attenuated relative to the mid and/or treble frequencies, which may indicate that the playback device is outdoors. As another example, the processor 202 may determine that the frequency response has one or more resonant frequencies (which may be caused by the room or objects therein), which may be indicated by one or more peaks and/or one or more valleys. In addition, the number of peaks and valleys may indicate a degree of irregularity of the environment (i.e. a number of objects within the environment and/or an irregularity of the arrangement of the walls).

Within examples, one of the one or more reflection characteristics may relate to a variance between the frequency response of the system and an “ideal” frequency response of the playback device. For instance, the reflection characteristic may be a difference between the “ideal” frequency response and the frequency response of the system. In some embodiments, the reflection characteristic may be a difference between the ideal frequency response and the current frequency response at a particular frequency range, such as bass, mid, or treble frequencies.

Determining the difference between the “ideal” frequency response and the current frequency response may involve, for each frequency response, integrating the respective frequency response over frequency for a portion of the frequency range. For instance, the processor 202 may integrate each frequency response over bass frequencies (e.g. 16 to 512 Hz). The processor 202 may then determine a difference between the integrated frequencies.

The “ideal” frequency response may be a frequency response of the playback device in a particular configuration. Further, the ideal frequency response may not be truly ideal, but rather an approximation of a playback device that is operating as designed. For instance, the “ideal” frequency response may be a frequency response of the playback device as determined in open space. Alternatively, the “ideal” frequency response may be a frequency response determined in an anechoic chamber. Further, the “ideal” frequency response of the playback device may be an approximation of a factory configured frequency response. For instance, the “ideal” frequency response may be a typical or average frequency response of playback devices of a particular type produced by a manufacturer.

In another embodiment, the playback device may determine the “ideal” frequency response as an aspect of a set-up procedure. For example, during the set-up procedure, a user of the playback device may be instructed to place the playback device in a particular arrangement so that the playback device may determine a frequency response. The particular arrangement may be, for instance, in the center of a room, among other examples.

FIG. 7 shows an illustrative plot of a frequency response of a playback device in a small room. Frequency response 702 shows the frequency response without an adjusted equalization setting. In a small room, the frequency response tends to have more peaks and valleys at bass frequencies, as shown, because bass frequencies may resonate more in a smaller room. Frequency response 704 shows the frequency response after an equalization setting for the small room has been applied. Compared to frequency response 702, the peaks and valleys are attenuated in frequency response 704, as shown.

One or more of the reflection characteristics may relate to an impulse response. For instance, an impulse response may indicate one or more reflections of the first audio signal. The impulse response may also indicate characteristics of the reflections, such as an amount of time elapsed between two reflections.

FIGS. 8A-8C show example impulse responses of a playback device. FIG. 8A shows an example impulse response of a playback device in (relatively) open space. After the initial excitation, the impulse response does not show a reflection, which may indicate that the playback device is outdoors, for example. FIG. 8B shows another example impulse response of a playback device that is near a wall. As shown in FIG. 8B, this impulse response includes a reflection of the impulse (near 8.6 ms), which may indicate the presence of a wall. FIG. 8C shows yet another example impulse response of a playback device. As shown in FIG. 8C, the impulse response includes two similar reflections of the impulse (near 8.6 ms and 12 ms). Such similarity may indicate that the two similar reflections are each off of the same wall.

As noted above, in some examples, the first media playback may detect a plurality of audio signals including audio signals emitted by the first media playback and/or audio signals emitted by other playback devices within the media playback system. In some embodiments, the playback device may determine one or more reflection characteristics for each of the detected audio signals (or a portion thereof). Alternatively, a reflection characteristic may be based on two or more audio signals in the plurality of detected audio signals. Other examples are possible as well.

Referring back to the example media playback system that include the first playback device and the second playback device, after detecting the fourth audio signal, the first playback device may then determine one or more reflection characteristics based on the fourth audio signal. Determining the one or more reflection characteristics based on the fourth audio signal may involve, for instance, any of the techniques described above for determining one or more reflection characteristics based on the second audio signal as discussed above.

While characteristics of detected audio signals have been referred to herein as reflection characteristics, in some embodiments, the audio signals may be detected before a reflection occurs. For instance, as noted above, an audio signal may propagate directly, such as from a first playback device to a second playback device.

d. Adjusting an Equalization Setting of the Playback Device Based on the One or More Reflection Characteristics.

At block 508, the playback device adjusts an equalization setting of the playback device based on the one or more reflection characteristics. For instance, one or more of the audio processing components 208 may be configured to alter the frequency response of the playback device. Specifically, the one or more audio components 208 may include one or more filters. When audio content passes through the one or more filters, the amplitude of certain frequencies (or frequency ranges) may be increased. The amplitude of other frequencies (or frequency ranges) may be decreased. Alternatively, the processor 202 may be configured to alter the frequency response of the playback device. The processor 202 may, for example, apply digital signal processing, such as a digital filter, to audio content.

As noted above, one of the one or more reflections characteristics may indicate a frequency or frequency range. The playback device may adjust an equalization setting based on the frequency or frequency range. For instance, if the reflection characteristic indicates bass frequencies are attenuated, the equalization setting may boost bass frequencies (as noted above, 16-512 Hz). Alternatively, if a particular frequency, such as (2 kHz) is a peak or a valley, the equalization may responsively attenuate or boost that frequency.

Adjusting the equalization setting may involve disabling a speaker of the playback device. For instance, the processor 202 may disable the a speaker 212 when the one or more reflection characteristics indicate that the listening experience may be improved by disabling the speaker. For example, an object in close proximity to the front of the speaker may cause distortion, such as muffling, of audio outputted by the speaker. Due to the distortion, the listening experience may be improved by disabling the speaker. In such a circumstance, one or more particular reflection characteristics may indicate that the first audio signal reflected off a close object, such as an object within 10 centimeters of the playback device. Alternatively, the one or more particular reflection characteristics may indicate that the frequency response of the playback device is distorted by the object.

Within examples, adjusting the equalization setting may involve selecting a particular equalization preset from a plurality of equalization presets based on at least one of the one or more reflection characteristics. Some of the equalization presets may be pre-determined. For example, each of the plurality of equalization presets may be a respective bass gain setting. For instance, a “small room” equalization preset may be pre-determined to attenuate bass frequencies. As another example, an “outdoors” equalization preset may be pre-determined to boost bass frequencies. The playback device may then adjust the equalization setting according to the selected particular equalization preset.

e. Causing an Audio Track to Play According to the Adjusted Equalization Setting.

In some embodiments, the playback device may perform block 510. At block 510, the playback device may cause an audio track to play according to the adjusted equalization setting. For instance, the playback device may provide the audio track to the audio processing components 208, which may be adjusted based on the equalization setting. The audio processing components 208 may alter frequency components of the audio track according to the equalization setting. The audio amplifier 210 may then amplify the signal which may cause the speaker(s) 212 to emit the audio track.

f. Sending to a Second Media Playback Device an Indication of the Reflection Characteristic

In some embodiments, the playback device may perform block 512. At block 512, the playback device may send to a second media playback device an indication of the reflection characteristic.

Playback devices of the media playback system may share their one or more respective reflection characteristics with the other playback devices in the media playback system. In some configurations, a particular playback device may share its one or more reflection characteristics with all of the playback devices in the media playback system. In other configurations, the particular playback device may share with a subset of playback devices. For example, the particular playback device may be grouped into a zone with three other playback devices, and the particular playback device may share its one or more reflection characteristics with the three other playback devices in its zone.

For instance, referring to FIG. 1, playback device 104 may send a particular reflection characteristic to playback devices 106, 108, and 110 that are grouped with playback device 104 into a zone. In turn, each of playback devices 106, 108, and 110 may receive the particular reflection characteristic. Playback devices 106, 108, and 110 may then send a respective particular reflection characteristic to playback device 104 and to each of the other playback devices in the zone. Each of the playback devices may send and/or receive reflection characteristics via a respective network interface, such as network interface 214 in FIG. 2.

In some circumstances, the playback device may adjust the equalization setting based on determined reflection characteristics from other playback devices within the media playback system. For instance, a particular playback device may adjust its equalization setting based on reflection characteristics from other playback devices grouped with the particular playback device in a zone. Basing the equalization setting on reflection characteristics from other playback devices may result in an equalization setting that is more appropriate for the environment.

For example, FIG. 6 shows an example configuration of a media playback system 100 that includes playback devices 602 and 604 that are grouped into a zone. Playback devices 602 and 604 may each emit a respective first audio signal, detect a respective second audio signal, and then determine a respective reflection characteristic that indicates the size of the room. Further, playback devices 602 and 604 may exchange respective reflection characteristics by sending and receiving the reflection characteristics over respective network interfaces.

The reflection characteristic determined by playback device 602 may indicate a smaller room than the reflection characteristic determined by playback device 604 because of the relative difference in how far the each emitted first audio signal travels before coming into contact with a respective wall that reflects the first audio signal, as shown. If playback devices 602 and 604 each base their respective equalization setting on their own respective reflection characteristic, then playback device 602 may adjust the equalization to a setting that is appropriate for a small room, while playback device 604 may adjust the equalization to a setting that is appropriate for a large room. In some circumstances, this difference in relative configurations may result in a mismatch in the frequency responses between playback device 602 and 604, which may worsen the listening experience for some users (yet, in other circumstances, this difference may be minor and may not have a significant impact on the listening experiences of users). However, as noted above, playback devices 602 and 604 may adjust the equalization setting based on determined reflection characteristics from one another. For instance, playback devices 602 and 604 may each average their determined reflection characteristic with the determined reflection characteristic of the other playback device. In this manner, the resulting adjusted equalization setting for each of playback devices 602 and 604 may be somewhere between that of a large room and a small room.

Within examples, each playback device of a media playback system may share its adjusted equalization setting with the other playback devices in the media playback system, such as by sending the adjusted equalization setting to other playback devices in the media playback system. In turn, one or more of the other playback devices may adjust their equalization setting based on the received equalization settings.

For instance, a first playback device and a second playback device that are grouped into a zone may each send to one another their respective adjusted equalization setting. Then, each of the first and second playback devices may adjust their respective equalization setting based on the received equalization setting. For example, the first playback device may determine that a particular one of the two adjusted equalization settings from either the first playback device or the second playback device is preferable for the environment. The first playback device may then (i) adjust its equalization setting based on the particular one of the two adjusted equalization settings and/or (ii) instruct the second playback device to adjust its equalization setting based on the particular one of the two adjusted equalization settings.
