Referring now to the drawings, wherein the showings are for purposes of illustrating one or more exemplary embodiments and not for purposes of limiting the same, FIG. 1 is a schematic view of an exemplary operating environment of a system 100 for providing a dynamic audio environment within a vehicle 102 according to an exemplary embodiment of the present disclosure. The components of the system 100, as well as the components of other systems, hardware architectures and software architectures discussed herein, may be combined, omitted or organized into different architecture for various embodiments. However, the exemplary embodiments discussed herein focus on the system 100 as illustrated in FIG. 1, with corresponding system components, and related methods.

As shown in the illustrated embodiment of FIG. 1, the vehicle 102 may include an electronic control unit (ECU) 104 that may be include a memory (not shown) that is configured to store instructions when executed by the ECU 104 that cause the ECU 104 to execute a dynamic audio environment application (dynamic audio application) 106. As discussed below, the dynamic audio application 106 may be configured to receive data associated with one or more audio streams that are played back through an audio system 110 of the vehicle 102 through one or more audio sources 112 of the vehicle 102. The one or more audio sources 112 may include various types of speakers that may be located at various portions of an interior cabin of the vehicle 102 (illustrated in an example of FIG. 2).

The one or more audio streams may include one or more types of audio that may be provided through various formats including, but not limited to, music (e.g., one or more genres of music), speech (e.g., radio talk show), live events (e.g., sporting events), and the like. The one or more audio streams may be based on various digital audio file system configurations that may include, but may not be limited to, waveform audio, uncompressed audio, compressed audio, and the like. Additionally, the one or more audio streams may be provided based on the execution of one or more digital audio files, the playback of a physical audio medium (e.g., compact-disc), the reception of radio waves and/or satellite based signals (e.g., AM radio, FM radio, satellite radio), and the like.

In an exemplary embodiment, the dynamic audio application 106 maybe configured to determine a vehicle mode of the vehicle 102 based on data that may be communicated by a vehicle mode control system 108 of the vehicle 102. The vehicle mode control system 108 may be configured to select a particular vehicle mode of a plurality of vehicle modes based on user selection and/or automatic selection of the particular vehicle mode. In one embodiment, each of the plurality of vehicle modes may impact the mechanical, electrical, and/or dynamic operation of the vehicle 102 during one or more driving conditions. For example, one or more of the vehicle modes may pertain a respective tightness or looseness of a steering of the vehicle 102, a respective suspension setting of the vehicle 102, a respective engine operation of the vehicle 102, and the like.

In an exemplary embodiment, the plurality of vehicle modes of the vehicle 102 may include but may not be limited to, an economy mode (eco-mode), a comfort mode, a sport mode, a snow mode, an autonomous mode, a quiet mode, and the like. As discussed below, upon determining the particular vehicle mode that is selected by the vehicle mode control system 108, the dynamic audio application 106 may select one or more particular audio effects that may alter (e.g., modify) a particular audio stream being played through the audio system 110 based on the manually selected vehicle mode of the vehicle 102 that may occur based on a driver's selection of one or more of vehicle modes.

The dynamic audio application 106 may also select one or more audio effects that alter a particular audio stream being played through the audio system 110 based on an automatically selected vehicle mode of the vehicle 102 that may be automated selected by the vehicle mode control system 108 based on a driver's driving style, road conditions, and/or environmental conditions at a particular point in time. The driver's driving style may be based on a speed of the vehicle 102, a braking rate of the vehicle 102, an acceleration rate of the vehicle 102, a braking force of the vehicle 102, a steering angle of the vehicle 102, and the like at one or more points in time. In some embodiments, one or more particular vehicle modes of the vehicle 102 may also be automatically selected based on road conditions. Additionally, one or more particular vehicle modes of the vehicle 102 may be automatically selected based on environmental conditions such as weather conditions, traffic conditions, and additional extrinsic conditions (e.g., slickness of the roadway on which the vehicle 102 is traveling, wind speed) that may persist within a surrounding environment of the vehicle 102.

As discussed below, the dynamic audio application 106 may be configured to operably control one or more of the audio sources 112 to provide the one or more audio streams being played through the audio system 110 in one or more manners. In particular, the one or more audio streams may be altered with one or more audio effects to provide an immersive audio experience within the vehicle 102 based on the manually or automatically selected vehicle mode of the vehicle 102. The altering of the audio streams with one or more types of audio effects may provide a listener with the sensation of being located within one or more environments that may compliment and/or correspond with the selected vehicle mode of the vehicle 102.

In particular, the altering of one or more audio streams with one or more types of audio effects may also provide a listener with a sensation of being located in one or more types and sizes of environments and/or one or more specific venues (e.g., a particular opera house), and/or environments that may include one or more particular sound effects. The audio effects may provide the listener with an acoustic experience that may replicate one or more environments that are larger than a physical size of an interior cabin of the vehicle 102, one or more environments that are equivalent to the physical size of the interior cabin of the vehicle 102, one or more environments that are smaller than the physical size of the interior cabin of the vehicle 102, one or more environments that replicate acoustics heard at one or more specific venues, and/or one or more environments that may include one or more particular sound effects that are based on the selected vehicle mode of the vehicle 102.

With reference to the components of the vehicle 102, the ECU 104 may operably control a plurality of components of the vehicle 102. In an exemplary embodiment, the ECU 104 of the vehicle 102 may include a processor (not shown), a memory, a disk (not shown), and an input/output (I/O) interface (not shown), which are each operably connected for computer communication via a bus (not shown). The I/O interface provides software and hardware to facilitate data input and output between the components of the ECU 104 and other components, networks, and data sources, of the system 100. In one embodiment, the ECU 104 may execute one or more operating systems, applications, and/or interfaces that are associated with the vehicle 102.

The one or more user interfaces may also allow the listener to manually select one or more audio sources 112 to be controlled to provide the one or more audio effects that may be manually selected by the listener or automatically selected based on the vehicle mode of the vehicle 102.

In another configuration, the one or more user interfaces may allow the listener to selectively enable one or more audio effects that replicate a particular pre-stored environment that may be consistent with one or more real-world venue audio environments. For example, the one or more user interfaces may allow the listener to selectively enable one or more audio effects that are associated with venue names that may be individually selected to replicate acoustics heard at a respective venue (e.g., a particular opera house). Upon the selection of the one or more audio effects, the application 106 may be configured to select one or more audio effects which replicate the acoustics that may be typically heard within the particular venue through one or more particular audio sources 112 of the vehicle 102.

In some embodiments, the one or more user interfaces may enable or disable the functionality of the dynamic audio application 106 with respect to the selection of one or more audio effects based on the selection of one or more vehicle modes of the vehicle 102. In circumstances that this functionality of the dynamic audio application 106 is disabled, the dynamic audio application 106 may select one or more default audio effects that may pertain to a respective format of the audio stream being played through the audio system 110 (discussed in more detail below).

In some embodiments, the one or more user interfaces may allow the listener to enable or disable additional vehicle effects that may be provided by the dynamic audio application 106 during selection of one or more audio effects and/or control of one or more particular audio sources 112 to provide the one or more audio effects. Such additional vehicle effects may include, but may not be limited to, digital effects that may be presented through one or more display screens, lighting effects that may be provided by one or more lighting sources within the interior cabin of the vehicle 102 and/or disposed at one or more external portions of the vehicle 102, seat adjustment effects that may pertain to one or more seats of the vehicle 102, climate control effects that may pertain to a climate control system (not shown) of the vehicle 102, and the like. For example, the one or more user interfaces may allow the listener to enable or disable various color temperatures of LED mood lighting effects of one or more lighting sources to promote sensations that may match one or more audio effects that are provided through one or more of the audio sources 112.

In an exemplary embodiment, the vehicle 102 may additionally include a storage unit 116. The storage unit 116 may store one or more operating systems, applications, associated operating system data, application data, vehicle system and subsystem user interface data, and the like that are executed by the ECU 104, the head unit 114, and one or more applications executed by the ECU 104 and/or the head unit 114 including the dynamic audio application 106.

In one or more embodiments, the storage unit 116 may be configured to store an audio stream data repository 118.

In one or more embodiments, the one or more audio profiles may also be configured to store data associated with particular audio effects that may be selected by the application 106. Such data may include particular audio effects that may be associated with particular vehicle modes of the vehicle 102. As discussed below, the dynamic audio application 106 may be configured to analyze a current audio stream that is being played through the audio system 110 to determine the format of the current audio stream. Upon determining the format of the current audio stream, the dynamic audio application 106 may be configured to access the audio stream data repository 118 to determine one or more default audio effects that may be associated with the format of the respective audio stream. The one or more default audio effects may pertain to audio effects that may be pre-stored as being suited for playing the respective format of the respective audio stream in a particular manner. For example, the one or more default audio effects may provide a predetermined level of mechanical audio effects, echoing audio effects, full range audio effects, midrange audio effects, high-bass audio effects, high-treble audio effects, high midrange audio effects, mid-bass audio effects, nose-canceling audio effects that may be based on the format of the audio stream being played through the audio system 110. As discussed below, the one or more default audio effects may be modified to one or more audio effects that are based on the selected vehicle mode of the vehicle 102 to alter the one or more audio streams and provide a dynamic audio environment to one or more listeners within the vehicle 102.

In one configuration, the audio stream data repository 118 may also be configured to store one or more audio profiles that may be associated with one or more particular listeners. The one or more listeners may utilize the one or more user interfaces of the dynamic audio application 106 to set one or more audio profiles that may include desired audio settings that may pertain to the selection of particular audio effects and/or the control particular audio sources 112 to provide various types of dynamic audio environments based on preferences of one or more particular listeners. In some circumstances, this functionality may allow one or more listeners to manually enable various simulated environments within the vehicle 102. For example, a listener may utilize a user interface of the dynamic audio application 106 to select a simulated environment of a particular venue to enable the application 106 to select one or more of particular audio effects and/or to control particular audio sources 112 to provide a simulated acoustic experience of being located at particular venue within the vehicle 102.

In an exemplary embodiment, the ECU 104 may be operably connected to the vehicle mode control system 108.

Some non-limiting illustrative examples of one or more audio effects that may be may pertain to one or more particular vehicle modes of the vehicle 102 that are selected by the dynamic audio application 106 will now be discussed. However, it is to be appreciated that numerous types of audio effects and/or combination of audio effects that may alter one or more audio streams may be provided during the selection of any of the vehicle modes. With particular reference to the one or more audio effects, the one or more audio effects may be provided in a manner that may allow a listener to feel as if the interior cabin of the vehicle 102 is more expansive based on the use of expansive echoing audio effects that may be provided through one or more particular audio sources 112. For example, if the vehicle 102 is determined to be in an eco-mode vehicle mode, the dynamic audio application 106 may be configured to select expansive echoing audio effects that may be provided through one or more particular audio sources 112 to give the listener a sensation of an expansive environment that may replicate a large opera house. This may provide the listener with an immersive experience that allows the listener to have a sensation of being in a simulated large environment (e.g., similar to a stadium, arena, opera house, auditorium) within the interior cabin of the vehicle 102. Accordingly, one or more audio streams may be provided in a manner through one or more selected audio sources 112 that may also provide a sensation of relaxation to the listener.

The one or more audio effects may also be selected by the application 106 in a manner that allow a transition effect of a sensation of being located within larger expansive environment to being located in an environment that is consistent with the size of an interior cabin environment of the vehicle 102. In other words, the one or more audio effects may be selected in a manner that are consistent with echoing and sound waves that are customarily heard within the interior cabin of the vehicle 102. Such audio effects may be provided by decreasing or removing the echoing audio effects and controlling one or more particular audio sources 112 that may enable the listener to hear one or more audio effects that provide the listener with a sensation of being located within an environment that is the size of the interior cabin environment of the vehicle 102. For example, if the vehicle mode of the vehicle 102 is determined to transition from the eco-mode to a comfort mode, one or more audio effects may be adjusted, ceased, and/or selected to transition from providing echoing audio effects that may replicate a larger expansive environment (e.g., concert hall) to an environment that is the consistent with the size of the interior cabin environment of the vehicle 102 (e.g., a uniquely in-vehicle audio experience).

The one or more audio effects may additionally be provided in a manner that allows a transition effect of the sensation of being located within an environment that is the size of the interior cabin environment of the vehicle 102 to the size and feel of a smaller more intimate environment. Such an environment may be provided by modifying particular audio effects and controlling one or more particular audio sources 112 to allow the listener to feel as if they are in a smaller, tighter, and/or more intimate environment. For example, if the vehicle mode of the vehicle 102 is determined to transition from the eco-mode or comfort mode to the sport mode, one or more audio effects may be adjusted and selected to transition from replicating a larger expansive environment or the vehicle interior cabin environment to a tighter more intimate smaller environment that may enable the listener to focus on the road and feel as if they have full control of the vehicle 102 (e.g., as the suspension and steering may be stiff in the sport mode vehicle mode).

The one or more audio effects may be provided in various manners that may be associated with the various vehicle modes that are selected by the vehicle mode control system 108 to replicate an environment in which different sound effects may be created and provided using different types of audio sources 112. In some embodiments, different sound effects may be provided through one or more audio effects to replicate external environments. For example, one or more audio effects may be provided by one or more selected audio sources 112 when it is determined that the vehicle 102 is in the snow mode to enable the listener to feel as if snow is absorbing sound waves and the sound is being dampened. It is appreciated that the dynamic audio application 106 may select numerous types and modifications of audio effects by controlling one or more types of audio sources 112 to provide various listening environments to the listener based on the selected vehicle mode of the vehicle 102 and/or based on manual selection of one or more audio effects by the listener.

FIG. 3 is a schematic overview of a plurality of modules 302-306 of the dynamic audio application 106 that are configured to execute computer-implemented instructions to provide the dynamic audio environment within the vehicle 102 according to an exemplary embodiment of the present disclosure.

It is to be appreciated that the dynamic audio application 106 may include one or more additional modules and/or sub-modules that are included in additional to or in lieu of the modules 302-306.

In one embodiment, the audio stream determinant module 302 may be configured to communicate with the audio system 110 of the vehicle 102 to determine a format of audio stream that may be currently played through the audio system 110 to be provided through the audio sources 112. As discussed, the one or more audio streams may include one or more formats of audio that may be provided in various formats including, but not limited to, music, speech, and/or live events.

In an exemplary embodiment, each audio stream format may be associated with the enablement of one or more default audio effects that may be associated with each of the respective formats. Accordingly, the audio stream determinant module 302 may analyze one or more sound clips of a predetermined length (e.g., 3 second sound clips at one or more portions of the audio stream) associated with a current audio stream to determine the format of the current audio stream. In some configurations, the audio stream determinant module 302 may analyze a digitally encrypted audio description that may be provided through radio waves, satellite based signals, and/or through a digital audio file to determine the format of the current audio stream. Upon determining the format of the current audio stream, the audio stream determinant module 302 may be configured to access the audio stream data repository 118 stored upon the storage unit 116 to determine one or more default audio effects that may be associated with the format of the respective audio stream.

As discussed, the one or more default audio effects may pertain to audio effects that may be pre-stored as being suited for playing back the respective format of the respective audio stream. In particular, the one or more default audio effects that may be associated with the format of the respective audio stream may be selected to provide the audio stream at one or more audio frequencies, with one or more echoing audio effects, at one or more treble levels, at one or more bass levels, and the like, through one or more audio sources 112 located at one or more particular portions 202, 204, 206 of the vehicle 102 and/or at or near one or more of the seats 208a-208d of the vehicle 102.

In some embodiments, the one or more default audio effects may be configured to replicate particular environments based on the format of the audio stream being played through the audio system 110. For example, if a current audio stream is determined to be a live event format that includes a live sporting event, the application 106 may select one or more default audio effects that may replicate a particular stadium environment in which the live sporting event is taking place. Upon determining the one or more default audio effects that may be associated with the format of the current audio stream, the audio stream determinant module 302 may be configured to communicate the one or more default audio effects to the audio effect execution module 306.

In an exemplary embodiment, the vehicle mode determinant module 304 may be configured to determine a current vehicle mode of the vehicle 102 as selected by the vehicle mode control system 108. As discussed above, the vehicle mode control system 108 may be configured to select a particular vehicle mode of the vehicle 102 based on a manual selection of the vehicle mode by the driver of the vehicle 102. Additionally, the vehicle mode control system 108 may be configured to select a particular vehicle mode of a plurality of vehicle modes of the vehicle 102 based on an automatic selection of the vehicle mode by the vehicle mode control system 108. Upon determining the current vehicle mode of the vehicle 102, the vehicle mode determinant module 304 may be configured to communicate the current vehicle mode of the vehicle 102 to the audio effect execution module 306 of the dynamic audio application 106.

In an exemplary embodiment, the audio effect execution module 306 of the dynamic audio application 106 may be configured to analyze the current vehicle mode of the vehicle 102 as communicated by the vehicle mode determinant module 304. The audio effect execution module 306 may additionally be configured to analyze the one or more default audio effects that may be associated with the format of the respective audio stream as communicated by the audio stream determinant module 302. Upon analyzing the current vehicle mode of the vehicle 102 and the one or more default audio effects, the audio effect execution module 306 may be configured to alter the audio stream by modifying the one or more default audio effects to select one or more audio effects that pertain to the vehicle mode of the vehicle 102.

In one or more embodiments, the audio effect execution module 306 may be configured to operably control the audio system 110 to select the one or more audio effects to be provided within the vehicle 102. In particular, upon modifying the one or more default audio effects to one or more audio effects that pertain to the selected vehicle mode of the vehicle 102, the audio effect execution module 306 may be configured to communicate with the audio system 110 to provide the one or more audio effects by one or more select audio sources 112 of the vehicle 102 to give the listener a particular sensation of being located in one or more types and sizes of environments and/or one or more specific venues that may be associated with the vehicle mode of the vehicle 102. Accordingly, the dynamic audio application 106 may alter the audio stream being played within the vehicle 102 to correspond with the vehicle mode of the vehicle 102 to provide an immersive dynamic audio environment within the vehicle 102.

FIG. 4 is a process flow diagram of a method 400 for selecting one or more audio effects and controlling one or more audio sources 112 to provide the one or more audio effects according to an exemplary embodiment of the present disclosure. FIG. 4 will be described with reference to the components of FIG. 1, FIG. 2, and FIG. 3 though it is to be appreciated that the method of FIG. 4 may be used with other systems and/or components. In the method of FIG. 4, a specific order of determining vehicle modes of the vehicle 102 are shown (i.e., eco-mode, comfort mode, sport mode, snow mode), however, it is understood that the method 400 and systems described herein may determine the vehicle modes of the vehicle 102 in any order and/or may determine additional or alternate vehicle modes of the vehicle 102. Additionally, it is to be appreciated that numerous types of audio effects and/or combination of audio effects to alter one or more audio streams that may not be specifically discussed below may be provided during the selection of any of the vehicle modes discussed in the process steps below and/or additional/alternate vehicle modes that are not discussed in the process steps below.

The method 400 may begin at block 402, wherein the method 400 may include analyzing a current audio stream to determine one or more default audio effects. In an exemplary embodiment, the audio stream determinant module 302 of the dynamic audio application 106 may be configured to communicate with the audio system 110 of the vehicle 102 to receive data associated with one or more audio streams being played back through one or more audio sources 112 of the vehicle 102. The audio stream determinant module 302 may be configured to communicate with the audio system 110 of the vehicle 102 to determine a format of an audio stream that may be currently played through the audio system 110 to be played through the audio sources 112. In one configuration, the audio stream determinant module 302 may analyze the received data associated with the current audio stream.

In one embodiment, the audio stream determinant module 302 may analyze one or more sound clips of a predetermined length (e.g., 3 second sound clips at one or more portions of the audio stream) associated with a current audio stream to determine the format of the current audio stream. In another embodiment, the audio stream determinant module 302 may communicate with the audio system 110 to determine a digitally encrypted audio description that may be provided to the audio system 110 through radio waves, satellite based signals, and/or through a digital audio file to determine the format of the current audio stream.

Upon determining the format of the current audio stream, the audio stream determinant module 302 may be configured to access the audio stream data repository 118 stored upon the storage unit 116 to determine one or more default audio effects that may be associated with the format of the respective audio stream. Upon determining the one or more default audio effects that may be associated with the format of the current audio stream, the audio stream determinant module 302 may be configured to communicate the one or more default audio effects to the audio effect execution module 306.

The method 400 may proceed to block 404, wherein the method 400 may include determining if the vehicle mode is the eco-mode. In an exemplary embodiment, the vehicle mode determinant module 304 of the dynamic audio application 106 may be configured to communicate with the vehicle mode control system 108 to determine a current vehicle mode of the vehicle 102. As discussed, the vehicle mode control system 108 may select a particular vehicle mode based on manual selection of the vehicle mode by a driver of the vehicle 102. Alternatively, the vehicle mode control system 108 may automatically select the vehicle mode based on data provided by the vehicle sensors 120 of the vehicle 102 that may be analyzed to determine driver's driving style, road conditions, and/or environmental conditions at a particular point in time. In one embodiment, the vehicle mode control system 108 may communicate the currently selected vehicle mode to the vehicle mode determinant module 304. If the vehicle mode is communicated by the vehicle mode control system 108 as the eco-mode, the vehicle mode control system 108 may determine that the vehicle mode is the eco-mode.

If it is determined that the vehicle mode is the eco-mode (at block 404), the method 400 may proceed to block 406, wherein the method 400 may include selecting one or more audio effects and controlling one or more audio sources 112 to replicate an expansive environment. In an exemplary embodiment, the audio effect execution module 306 may be configured to communicate with the audio stream determinant module 302 to receive one or more default audio effects that may be determined by the module 302 as being associated with the format of the current audio stream.

Accordingly, the vehicle mode determinant module 304 may communicate that the currently selected vehicle mode is the eco mode. In an exemplary embodiment, upon determining that the vehicle mode is the eco-mode, the audio effect execution module 306 may be configured to alter the audio stream by modifying the one or more default audio effects to one or more audio effects that pertain to the eco-mode vehicle mode. In particular, the audio effect execution module 306 may be configured to communicate with the audio system 110 to modify the one or more default audio effects to select one or more audio effects as echoing audio effects that may be provided by one or more select audio sources 112 of the vehicle 102 to give the listener the feeling of an expansive environment that may replicate a large opera house.

In one configuration, during the transition from the one or more default audio effects to the echoing audio effects, the audio effect execution module 306 may communicate with the audio system 110 to provide a transition effect that may selectively utilize mechanical audio effects, echoing audio effects, full range audio effects, midrange audio effects, high-bass audio effects, high-treble audio effects, high midrange audio effects, mid-bass audio effects, nose-canceling audio effects, and the like to provide a sensation of an area of expansion with respect to the cabin of the vehicle 102. Such a sensation may be associated with acoustics that provide a feeling of increasing from an environment that is the size of the interior cabin environment of the vehicle 102 to a larger expansive environment. Upon providing the transitioning effect through one or more audio sources 112, the audio effect execution module 306 may operably control the audio system 110 to provide the audio stream through one or more of the audio sources 112 in a manner that gives the listener the feeling of an expansive environment that may replicate a large opera house as the vehicle 102 is being driven in the eco-mode vehicle mode.

If it is determining that the vehicle mode is not the eco-mode (at block 404), the method 400 may proceed to block 408, wherein the method 400 may include determining if the vehicle mode is the comfort mode. As discussed above, the vehicle mode determinant module 304 may be configured to communicate with the vehicle mode control system 108 to determine a currently selected vehicle mode of the vehicle 102. In one embodiment, the vehicle mode control system 108 may communicate the currently selected vehicle mode to the vehicle mode determinant module 304. If the currently selected vehicle mode is communicated by the vehicle mode control system 108 as the comfort mode, the vehicle mode control system 108 may determine that the vehicle mode is the comfort mode.

If it is determined that the vehicle mode is the comfort mode (at block 408), the method 400 may proceed to block 410, wherein the method 400 may include selecting one or more audio effects and controlling one or more audio sources 112 to provide audio consistent with an environment that is the size of the vehicle interior environment. As discussed, the audio effect execution module 306 may be configured to communicate with the audio stream determinant module 302 to receive one or more default audio effects that may be determined by the module 302 as being associated with the format of the current audio stream.

In other words, the one or more audio effects may be selected in a manner that are consistent with echoing and sound waves that are heard normally within an interior cabin 200 of the vehicle 102.

In one configuration, during the transition to one or more audio effects that may be provided by one or more select audio sources 112 of the vehicle 102 to give the listener a sensation that is consistent with an environment that is the size of the interior cabin 200, the audio effect execution module 306 may communicate with the audio system 110 to provide a transition effect that may selectively utilize mechanical audio effects, echoing audio effects, full range audio effects, midrange audio effects, high-bass audio effects, high-treble audio effects, high midrange audio effects, mid-bass audio effects, nose-canceling audio effects, and the like to provide a sensation of an area of the cabin of the vehicle 102 changing to an environment that is the size of the vehicle interior environment. Such a sensation may be associated with acoustics that provide a feeling of being relocated from an environment that is the size of a larger expansive environment to an environment that is the size of the interior cabin of the vehicle 102. Alternatively, such a sensation may be associated with acoustics that provide a feeling of being relocated from an environment that is the size of a smaller environment to an environment that is the size of the interior cabin of the vehicle 102

As an illustrative example, if the vehicle 102 is determined to transition from the eco-mode to the comfort mode, one or more audio effects may be provided as a transition effect to provide a transition from providing echoing audio effects that may replicate a larger expansive environment such as a concert hall to an environment that is the consistent with the size of the interior cabin environment of the vehicle 102 (e.g., that may provide a uniquely in-vehicle audio experience). The audio effect execution module 306 may thereby operably control the audio system 110 to provide the audio stream through one or more of the audio sources 112 in a manner that gives the listener the feeling of being located within the vehicle interior cabin.

With continued reference to FIG. 4, if it is determined that the vehicle mode is not the comfort mode (at block 408), the method 400 may proceed to block 412, wherein the method 400 may include determining if the vehicle mode is the sport mode. In one embodiment, the vehicle mode control system 108 may communicate the currently selected vehicle mode to the vehicle mode determinant module 304. If the currently selected vehicle mode is communicated by the vehicle mode control system 108 as the sport mode, the vehicle mode control system 108 may determine that the vehicle mode is the sport mode.

If it is determined that the vehicle mode is the sport mode (at block 412), the method 400 may proceed to block 414, wherein the method 400 may include selecting one or more audio effects and controlling one or more audio sources 112 to replicate a small environment. As discussed, the audio effect execution module 306 may be configured to communicate with the audio stream determinant module 302 to receive one or more default audio effects that may be determined by the module 302 as being associated with the format of the current audio stream. The audio effect execution module 306 may additionally be configured to analyze the one or more default audio effects that may be associated with the format of the respective audio stream.

The audio effect execution module 306 may also be configured to communicate with the vehicle mode determinant module 304 to determine the currently selected vehicle mode of the vehicle 102.

In one configuration, during the transition to one or more audio effects that may be provided by one or more select audio sources 112 of the vehicle 102 to give the listener a sensation that is consistent with being located within the smaller more intimate and tight environment, the audio effect execution module 306 may communicate with the audio system 110 to provide a transition effect that may selectively utilize mechanical audio effects, echoing audio effects, full range audio effects, midrange audio effects, high-bass audio effects, high-treble audio effects, high midrange audio effects, mid-bass audio effects, nose-canceling audio effects, and the like to provide a sensation of an area of the cabin of the vehicle 102 changing to an environment that is the size of a larger environment to the smaller more intimate and tight environment. Such a sensation may be associated with acoustics that provide a feeling of being relocated from an environment that is the size of larger environment to an environment that is the size of a smaller more intimate and tight environment.

As an illustrative example, if the vehicle 102 is determined to transition from the eco-mode to a sport mode, one or more audio effects may be provided as a transition effect to provide a transition from providing echoing audio effects that may replicate a larger expansive environment such as a concert hall to an environment that is the smaller more intimate and tight environment. Alternatively, if the vehicle 102 is determined to transition from the comfort mode to the sport mode, one or more audio effects may be provided as a transition effect to provide a transition from providing echoing audio effects that may give the listener the feeling of being located within the vehicle interior cabin to an environment that is the smaller more intimate and tight environment. The audio effect execution module 306 may thereby operably control the audio system 110 to provide the audio stream through one or more of the audio sources 112 in a manner that gives the listener the feeling of being located within the smaller more intimate and tight environment.

With continued reference to FIG. 4, if it is determined that the vehicle mode is not the sport mode (at block 412), the method 400 may proceed to block 416, wherein the method 400 may include determining if the vehicle mode is the snow mode. In one embodiment, the vehicle mode control system 108 may communicate the currently selected vehicle mode to the vehicle mode determinant module 304. If the currently selected vehicle mode is communicated by the vehicle mode control system 108 as the snow mode, the vehicle mode control system 108 may determine that the vehicle mode is the snow mode.

If it is determined that the vehicle mode is the snow mode (at block 416), the method 400 may proceed to block 418, wherein the method 400 may include selecting one or more audio effects and controlling one or more audio sources 112 to replicate snow absorption of sound waves. In one embodiment, the audio effect execution module 306 may be configured to communicate with the audio stream determinant module 302 to receive one or more default audio effects that may be determined by the module 302 as being associated with the format of the current audio stream.
