The present disclosure allows multiple musicians working remotely, and with a respective DAW, to collaborate with each other and share music files. This approach provides serval advantages: (1) the sharing of music data avoids external services like email, Dropbox or iCloud in favor of native musical data by which near-real-time synchronization of contributions to a musical piece is achieved, (2) a producer can arrange different parts—a bass player can contribute a bassline idea, a vocalist can sing and record an audio track that becomes the vocal part of the musical composition, and so forth, and (3) it allows musicians to work with their existing software and hardware, including across multiple different DAWs and operating systems. For example, a bass player may use Pro Tools on Microsoft Windows, while the producer may use Logic Pro, or another, different DAW, on Apple OS or other operating system.

Referring now to the Figures, FIG. 1 is a schematic block diagram of an exemplary system 100 by which the present disclosure can be embodied. System 100 may implement a collaborative environment in which musicians can compose music. The system 100 may comprise a plurality of computer workstations 130a-130n, representatively referred to herein as workstation(s) 130 communicatively coupled to a central server 110. Workstations 130 and server 110 may comprise resources including, but not limited to input-output (IO)/communications components 122a-122d, representatively referred to herein as IO/communications component(s) 122, processor components 125a-125d, representatively referred to herein as processor component(s) 125, and memory components 128a-128d, representatively referred to herein as memory component(s) 128. As illustrated in FIG. 1, resources on workstations 130 may realize digital audio workstations (DAWs) 140a-140n, representatively referred to herein as DAW(s) 140, by which composers may compose music.

In an embodiment, server 110 may accept data representing music segments and may compare received music segments with previously stored music segments to determine if there are any updates include in the received music segments to identify a new version of the music segment and compile or otherwise integrate the music segments into a single piece of music, as further described below.

FIG. 2A and FIG. 2B provide schematic block diagrams of an exemplary musical collaboration system 200 by which the present disclosure can be embodied. Musical collaboration system 200 represents various software components that may be implemented on the hardware of system 100. For example, DAWs 230a-230c may be implemented on workstations 130 (as DAWs 140, for example) and application programing interface (API) 220 and data storage 210 may be implemented on server 110. Further, in another embodiment, API 220 and data storage 210 may be implemented at DAWs 230a-230c. Other configurations are possible, examples of which are described below.

In an embodiment, and as illustrated in FIG. 2A, DAWs 230a-230c may be a music software application that is integrated with plugins 240a-240c to initiate or access a musical collaboration session. In another embodiment, DAWs 230a-230c may be a music software application in which plugins 240a-240n may be instantiated by a drag-and-drop operation to initiate or access a musical collaboration session. The musical collaboration session may be conducted between DAWs 230a-230c by API 220 that is hosted at server 110.

In an embodiment, and as illustrated in FIG. 2B, DAWs 230a-230c may be a music software application that communicates directly with API 220 that is hosted at server 110, thereby obviating plugins 240a-240c.

In the example of FIG. 2A and FIG. 2B, three (3) DAWs 230a-230c are outfitted for musical collaboration. It can be appreciated, however, that any number of DAWs may be used in conjunction with the embodiments disclosed herein. DAWs 230a-230c may employ a set of channels 250a-250c, which can be audio channels representing sound waveforms produced by specific instruments (including vocals) or MIDI channels representing instrument-agnostic musical note data. Those having skill in the art will recognize how audio and/or MIDI channels can be realized in a DAW without explicit details being set forth herein.

In one embodiment, the set of channels 250a-250c of the DAWs 230a-230c may be audio channels, for example, a “bass” channel, a “vocal” channel, a “kick drum” channel, a “guitar” channel, a “piano” channel, a “violin” channel, or “master” channel, although any other type of musical instrumental data may also be included as part of the audio channels.

In this example a “bass” channel is a channel dedicated to bass musical data, similarly a “vocal” channel is a channel dedicated to vocals data, a “kick drum” channel is a channel dedicated to kick drum musical data, a “guitar” channel is a channel dedicated to guitar musical data, a “piano” channel is a channel dedicated to piano musical data, and a “violin” channel is a channel dedicated to violin musical data. Further, a master channel is a channel that includes data from all types of musical parameter channel categories.

In another embodiment, the audio channels including a “bass” channel, a “vocal” channel, a “kick drum” channel, a “guitar” channel, a “piano” channel, a “violin” channel, may be referred to as musical parameter channel categories.

Embodiments may implement several features by which DAWs 230a-230c intercommunicate in a controlled manner with each other and with API 220 and data storage 210 to enable collaboration of multiple composers on a single musical composition. Such features may be additional to those already implemented in DAWs 230a-230c, such as through plugins 240a-240c shown in FIG. 2A. However, the same features may be implemented as functionality of the DAWs 230a-230c itself, as shown in FIG. 2B, thus obviating the need for a plugin. As it relates to FIG. 2A, the set of features may be the same across all plugins 240a-240c, functionality of such features being constrained at those DAWs operated by guest composers. For example, functionality of DAWs 230b-230c may be limited when primary control over the collaboration process is affected at one or more DAWs 230a-230c operated by a host composer (i.e., DAW 230a).

In certain embodiments, the designation of which DAW 230a-230c is the host and which are guests corresponds to the composer that initiates a collaborative session. In the illustrated embodiments of FIG. 2A and FIG. 2B, the host/guest functionality is indicated at host controls/processor 245a and guest controls/processors 245b-245c.

In an embodiment, the DAWs 230a-230c may collaborate together over a session to compose music. For example, and in view of FIG. 2A, when a DAW 230a is associated with a host user, the host user initiates a collaborative session by accessing a DAW 230a-230c that is integrated with plugins 240a-240c to initiate or access a musical collaboration session. Upon accessing the music collaboration application, a user interface is generated that displays a prompt offering one of two options: (1) “Host a session” or (2) “Join an existing session”. When the host user selects the (1) “Host a session” prompt, a new collaborative session is initiated between the DAW 230a and API 220. Upon initiating the new collaborative session as a host, the DAW 230a would now be referred to as a host composer device 230a. This new collaborative session is assigned a unique session ID 260 by the API 220. API 220 provides the session ID to the DAW 230a. Session ID 260 may take the form of a hyperlink or textual data that can be entered into a suitable text entry box to provide access to the new collaborative session. DAW 230a may provide the session ID 260 to other guest users associated with the DAW 230b-230c. Once session ID 260 has been selected by guest users accessing DAWs 230b-230c, host DAW 230a and guest DAWs 230b-230c can collaborate on a common musical composition. Upon accessing the new collaborative session by selecting the session ID 260, the DAWs 230b-230c may be referred to as guest composer devices 230b-230c.

In an embodiment, DAWs 230a-230c may be associated, or otherwise bound, together by a session ID 260 which may be generated by API 220 or other ID generating mechanisms upon instantiation of a collaborative session. For example, when host DAW 230a instantiates a collaborative session and activates host controls/processor 245a, API 220 may generate a session ID 260 which may be provided to other DAWs, such as DAWs 230b-230c, for purposes of entering into the session. Session ID 260 may take the form of a hyperlink or textual data that can be entered into a suitable text entry control of guest controls/processors 245b-245c. Once session ID 260 has been selected by guest DAWs 230b-230c, host DAW 230a and guest DAWs 230b-230c can collaborate on a common musical composition.

During a collaborative session, each user, including the host user associated with the host composer device 230a and the guest composer(s), may identify the channels 250a-250c on which they wish to compose. The contributions produced at host DAW 230a and guest DAWs 230b-230c may be stored in memory circuitry, e.g., data storage 210. In one embodiment, API 220 realizes processor-callable procedures by which such contributions are stored in a cloud storage facility, where, in this case, data storage 210 may implement such storage. As is discussed further below, the stored contribution data, referred to herein as pancake data, may be combined or otherwise assembled into a candidate musical composition that can ultimately become a finalized musical composition. In an embodiment, the finalized musical composition may be determined upon approval of the candidate musical composition by the host composer. The candidate musical composition can be visible to each of the host DAW 230a and guest DAWs 230b-230c in the API 220.

FIG. 3 is a flow diagram of an exemplary collaboration process 300, in view of FIG. 2A, according to an embodiment of the present disclosure. This exemplary collaboration process 300 is implemented by server 110 that is configured to execute functions (software instructions) that perform one or more of the operations of the exemplary collaboration process 300. In an embodiment, server 110 may be a local server or a remote server, as appropriate. Server 110 hosts the API 220 and the API 220 is in communication with DAWs 230a-230c. Each DAW 230a-230c communicates instructions to API 220 via a respective plugin 240a-240c.

As described above, DAWs 230a-230c may be a music software application that is integrated with plugins 240a-240c to initiate or access a musical collaboration session. In an embodiment, DAWs 230a-230c may be a music software application in which plugins 240a-240n may be instantiated by a drag-and-drop operation to initiate or access a musical collaboration session. The musical collaboration session may be conducted between DAWs 230a-230c by API 220 that is hosted at server 110. Though a musical collaboration session is described above with reference to server 110 and API 220, it can be appreciated that, in another embodiment, the musical collaboration session may be realized by a local area network or other local connectivity tool (e.g. Bluetooth), which allows direct connection of devices on a local network without need for server 110 and API 220, which is hosted on server 110.

At step 305 of process 300, server 110 receives an activation request from any one of DAWs 230a-230c to initiate a musical collaboration session. In one embodiment, the DAWs 230a-230c may collaborate together over a session to compose music. For example, a user of DAW 230a corresponding to the computer workstation 130a may initiate a musical collaboration session or may access an ongoing musical collaboration session by accessing the plugin 240a integrated into the DAW 230a. The user interacts with the plugin 240a, either by clicking on the plugin 240a that is integrated into the DAW 230a or by a drag-and-drop operation of the plugin 240a onto the DAW 230a. In response, a user interface is generated on the computer workstation 130a. The user interface displays a prompt offering two options, as described above: (1) “Host a session” or (2) “Join an existing session”. In this embodiment, the user selects “Host a session” and, in response, the selection plugin 240a of DAW 230a transmits an activation request for a new collaborative session to server 110 and the flow diagram proceeds to step 310.

In an embodiment, when the user selects “Join an existing session” on the user interface, plugin 240a of DAW 230a transmits a request to server 110 to join an existing session, and the flow diagram proceeds directly to step 330, which is described in greater detail below.

At step 310 of process 300, server 110, in response to receiving the activation request from plugin 240a, initiates a new collaborative session between the DAW 230a and API 220 hosted at the server 110. Initiating a new collaborative session between the DAW 230a and API 220 is performed by opening a communication channel dedicated between the DAW 230a and API 220 in order to transmit and receive data utilizing a session initiation protocol (SIP protocol). Upon initiating the new collaborative session, server 110 identifies DAW 230a as a host composer device 230a. Further, the communication channel of the new collaborative session is assigned a unique session ID 260 by the API 220. API 220 transmits the session ID to the host composer device 230a, or DAW 230a. Session ID 260 may take the form of a hyperlink or textual data that can be entered into a suitable text entry box by guest users to join the communication channel of the new collaborative session.

At step 315 of process 300, server 110 receives, as a portion of a musical composition stored at the server 110, first musical input data. The first musical input data may be generated by DAW 230a and stored with the musical composition in memory of the server 110. The musical composition, as obtained by the server 110 at step 315 of process 300, can be referred to as a stored musical composition, as in FIG. 4 (explained below). The musical composition may be a piece of a song, a complete song, or a piece of music from a musical instrument, although any piece of music may also be included in a musical composition. In one embodiment, the musical composition may be previously uploaded and stored in the memory of the server 110. The musical composition may also be referred to as a musical piece. In another embodiment, the musical composition may be stored in the memory based on a previous collaboration session performed by DAW 230a. In an embodiment, the musical composition may upload a file of the musical composition on to the server 110 by DAW 230a.

In an embodiment, contributions to the musical composition may be uploaded to the server 110 in real time by DAW 230a. This may be performed by a user of DAW 230a, by playing live music using a musical instrument or by singing using DAW 230a to upload the respective contribution to the musical composition on the server 110 over MIDI channels. In another embodiment, a musician can program MIDI using a keyboard or mouse, and can also use audio samples or synthesis to create sound. When the musical composition is previously stored in the memory of the server 110, then the server 110 may receive a request with an identifier of the musical composition from DAW 230a, during this operation, in order to access that musical composition and add the respective contribution.

At step 320 of process 300, the server 110 receives, from DAW 230a, a selection of musical parameter channel category associated with first musical input data. In one embodiment, the set of channels 250a-250c of the DAWs 230a-230c may be referred to as musical parameter channels. Each of the channels 250a-250c is a communication channel to transmit a musical parameter category of music. By way of example, musical parameter categories associated with channels 250a-250c may include, for example, a “Channel 1”, “Channel 2”, or “Channel 3”, or, in the event the instrument is known, a “bass” channel, a “vocal” channel, a “kick drum” channel, a “guitar” channel, a “piano” channel, a “violin” channel, or a “master” channel. Of course, any other type of musical instrument data may also be included as part of the audio channels. In this example a “bass” channel is a channel dedicated to bass musical data, similarly a “vocal” channel is a channel dedicated to vocals data, a “kick drum” channel is a channel dedicated to kick drum musical data, a “guitar” channel is a channel dedicated to guitar musical data, a “piano” channel is a channel dedicated to piano musical data, and a “violin” channel is a channel dedicated to violin musical data. Further, a “master” channel is a channel that includes data from all types of musical parameter channel categories. The channels 250a-250c corresponding with the individual musical parameter categories, including a “bass” channel, a “vocal” channel, a “kick drum” channel, a “guitar” channel, a “piano” channel, a “violin” channel, are referred to as musical parameter channel categories.

In an embodiment, and in response to receiving the selection of musical parameter channel category, the server 110 may be configured to only sync the data associated with the selected channel(s). In an example, if the server 110 receives the selection of a “guitar” channel, then the server 110 would be monitoring for any changes in the “guitar” channel to sync during the collaborative session and would ignore the other channels. In another example, if the server 110 receives the selection of a “master” channel, then server 110 would be monitoring for any changes in all of the channels to sync during the collaborative session. Monitoring for changes by the server 110 is further explained below.

In certain embodiments, the exact names of channels in guest DAWs 230b-230c can be used, such as “Guitar 1” and “Guitar 2” channels. The host DAW 230a may be provided control over which parts of the composition are included in each iteration of the collaborative effort and which parts are excluded from such iterations. Musical collaboration system 200 may name each part through automatic or manual techniques as selected by the user.

At step 325 of process 300, the server 110 transmits the session ID generated at step 310 of process 300 to DAWs 230b-230c. The server 110 may provide the session ID 260 to DAW 230b-230c based on pre-defined transmission rules. DAWs 230b-230c are considered as potential guest users who may be interested in joining the new collaborative session. Pre-defined transmission rules may include, upon generating the session ID 260, the server 110 may automatically transmit the session ID 260 to DAW 230b-230c. Another transmission rule may include transmitting the session ID 260 at a predefined time to DAW 230b-230c. Other types of transmission rule may also be included. The transmission of the session ID 260 to DAW 230b-230c may be over a communication platform, by way of example, a communication platform may include an email message, chat message, or, text message, although any other types of communication platforms may also be included.

In an embodiment, DAW 230a may directly provide the session ID 260 to other potential guest users associated with the DAW 230b-230c, by sending the session ID in an email message, chat message, or, text message.

At step 330 of process 300, the server 110 receives a request to join the new collaborative session initiated by the host DAW 230a from DAW 230b-230c. Once session ID 260 is accessed, either by clicking a link of the session ID or by entering a textual data that can be entered into a suitable text entry box by guest users of guest composer devices DAWs 230b-230c, guest composer devices DAWs 230b-230c are presented with a user interface that provides options of “Join an existing session”. When “Join an existing session” is selected, DAWs 230b-230c are given access to join the new collaborative session initiated by the host DAW 230a to collaborate together over a joint collaboration session. Upon the DAWs 230b-230c joining the new collaborative session, the server 110 identifies DAWs 230b-230c as guest composer devices 230b-230c.

At step 335 of process 300, the server 110 receives second musical input data from DAWs 230a-230c. Second musical input data may be a segment of an existing channel of the musical composition or may be a unique channel to be added to the musical composition. In this embodiment, the second musical input data may be uploaded to the server 110 in real time by DAWs 230a-230c over, for instance, MIDI channels. The second musical input data may be performed by a user of DAW 230a-230c, by playing live music using a musical instrument or by singing using DAWs 230a-230c, and uploaded 10 the server 110. In another embodiment, a musician can program MIDI using a keyboard or mouse, and can also use audio samples or synthesis to create sound.

In an embodiment, the DAWs 230a-230c may upload a file of contribution channels of the musical composition to memory at the server 110. In another embodiment, the DAWs 230a-230c may upload a file of contribution channels of the musical composition to database storage of the server 110, the database storage being a file system or, put another way, a Content Delivery Network, an Online Locker, an Online File System, and the like.

In an embodiment, and when the musical composition is previously stored in memory at the server 110, the server 110 may receive a request with an identifier of the musical composition from DAWs 230b-230c to access that musical composition.

At step 340 of process 300, the server 110 generates musical pieces by identifying new musical segments of the channels of the musical composition based on syncing performed between channels of the musical composition stored in the memory at the server 110 and the second musical input data received at step 335 of process. The second musical input data may, in an example, be associated with an existing channel of the musical composition.

In one embodiment, the musical composition may be uploaded and stored in the memory of the server 110. The memory of server 110 may be a database storing musical input data from respective channels. In an embodiment, the musical composition may be stored from a previous collaboration session performed by DAWs 230a-230c. In an embodiment, the musical composition may be a file of the musical composition uploaded to the server 110 by DAWs 230a-230c.

Functions of step 340 of process 300 are further explained with reference to FIG. 4. FIG. 4 is a schematic block diagram of an exemplary new musical segments generation process 400, according to an embodiment of the present disclosure. It is to be understood that while new musical segment generation process 400 resembles an electrical circuit, embodiments of the present disclosure realize the processing through software, e.g., processor instructions executed by processors 125b-125d of FIG. 1.

FIG. 4 shows steps performed at server 110 and illustrates an embodiment of the present disclosure that maintains a buffer of “new musical input data” 405 indicated in the figure at new data buffer memory 410 at the server 110. In view of FIG. 3, the new musical input data 405 may be referred to as the second musical input data received, from DAWs 230a-c, during step 335 of process 300.

The new musical input data may be received during the collaborative session from a host composer device, in this example, DAW 230a, over the audio channels selected at step 320 of process 300. In this example, the selected audio channel is a “Guitar” channel. Accordingly, the new audio a piece of music would include music associated with the Guitar channel. The new musical input data may be played by DAW 230a by either playing instruments live (i.e., real time) or by playing a musical piece that was stored on the workstation 130a of DAW 230a. The new musical input data may be received by API 220 of musical collaboration system 200 from DAW 230a. When a collaborative session is initialized, the new audio, which corresponds to the selected audio channel of “Guitar”, is received by the new data buffer 410 and passed on to API 220 of server 110 to perform step 420 of process 400. In an embodiment, the new musical input data may be received during the collaborative session from a host composer device, or DAW 230a, as well as from guest composer devices DAW 230b-c.

At step 420 of process 400, API 220 of the server 110 receives the new musical input data 405 and compares it with audio, of a corresponding channel, that is present in the stored musical composition in musical composition storage 415 at the server 110. As will be described herein, the comparison may be performed for a given channel of the musical composition. It can be appreciated, however, that the comparison may be for more a multitude of corresponding channels of the musical composition, based on the new musical input data 405 provided to the server 110.

In an example of new musical input data 405, or new data 405, named “Song AA”, API 220 of the server 110 compares the audio received from a guitar channel of “Song AA” and the previously stored audio data from the guitar channel of “Song AA”, or the stored musical composition. When API 220 of the server 110 identifies that at least a portion of the new musical input data 405 is different from a corresponding portion of the stored audio of the musical composition in storage 415, the API 220 of server 110 transmits the new audio 405 to the musical composition storage 415 at step 420 of process 400. Further, at step 420 of process 400, the API 220 of the server 110 transmits that portion of the new audio 405 to step 425 of process 400.

However, in an embodiment, when the API 220 of the server 110 identifies, at step 420, that at least a portion of the new audio 405 is not different with a corresponding portion of the stored audio in the musical composition storage 415, API 220 of the server 110 may transmit the new musical input data to components of musical collaboration system 200. Musical collaboration system 200 may act as a pass-through audio entity, receiving audio input and outputting the same signal without that signal being audibly affected. From the user experience standpoint, this implementation is transparent to the host user, which simply activates a control such as a spacebar to start playback at which point musical collaboration system 200 processes audio or MIDI data as a background procedure.

In an embodiment, when API 220 of the server 110 receives, at step 420 of process 400, the new audio 405, compares it with the audio that is stored in the musical composition storage 415 on the server 110, and identifies that there are no similarities between the new audio 405 and the stored musical composition, the API 220 of the server 110 transmits the new audio 405 to the musical composition storage 415. In an example, the new audio 405 may be “Song AA” and the API 220 of the server 110 may determine that the new audio 405 includes musical input data from a new channel of the musical composition, and so the new audio 405 may be transmitted to the musical composition storage 415 along with the identifier of the audio file i.e. “Song AA”.

In an embodiment, and at step 420 of process 400, the API 220 of the server 110 identifies that at least a portion of the new audio 405 is different from a corresponding portion of the stored audio in the musical composition storage 415 and transmits the new audio 405 to the musical composition storage 415. Further, the API 220 performs step 430 of process 400, where an audio encoder processes the different portion of the new audio 405 to generate a pancake data file 435 without input from the API 220 of the server 110.

In another embodiment, and at step 420 of process 400, the API 220 of the server 110 transmits the new audio 405 to the musical composition storage 415 regardless of the presence of corresponding portions of the stored audio in the stored musical composition. Thus, the API 220 performs step 430 of process 400, where the audio encoder processes the portion of the new audio 405 to generate the pancake data file 435 without input from the API 220 of the server 110.

Assuming step 420 of process 400 identifies portions of new audio 405 that are different from stored audio in the musical composition storage 415, step 425 of process 400 includes determining, by the API 220 of the server 110, if the portion of the new audio 405 exceeds a predefined threshold time duration. When the API 220 of the server 110 determines that the portion of the new audio 405 does exceed a predefined threshold time duration, then the API 220 of server 110 transmits that portion of the new audio 405 to the audio encoder 430.

For example, the predefined threshold time duration may be 4 seconds. Assume the new audio contains 60 seconds of music and the identified portion of the new audio 405 that matches with the corresponding portion of the stored audio in musical composition storage 415 has a duration of 55 seconds at the beginning of the 60 second block. In this example, the first 55 seconds of the new audio has not changed in comparison to the corresponding stored audio. Thus, the identified portion of the new audio 405 that is different from the corresponding portion of the stored audio is the last 5 seconds, meaning that the identified portion of the new audio 405 that starts at 55 seconds and runs for 5 seconds until it reaches the 60 second mark exceeds the predefined threshold time duration of 4 seconds. Accordingly, as the threshold monitoring module 425 determines that the portion of the new audio 405 of with a time duration of 5 seconds does exceed a predefined threshold time duration of 4 seconds, then the threshold monitoring module 425 transmits that portion of the new audio 405 to the audio encoder 430. Further, as described above, this portion of the new audio 405 is also referred to as a “pancake data”. In an embodiment, there may be multiple musical pieces also referred to as pancake data that may be identified during a musical collaboration session.

Of course, when the threshold monitoring module 425 determines that the portion of the new audio 405 that is different from the audio stored in the musical composition storage 415 does not exceed a predefined threshold time duration, then the threshold monitoring module 425 determines that no action is to be taken.

For example, the predefined threshold time duration may be 10 seconds. Assume the new audio contains 60 seconds of music and the identified portion of the new audio 405 that matches with the corresponding portion of the stored audio in the musical composition storage 415 has a duration of 5 seconds at the end of the 60 second block. In this example, the first 55 seconds of the new audio has not changed in comparison to the corresponding stored audio. Thus, the identified portion of the new audio 405 that is different from the corresponding portion of the stored audio is the last 5 seconds of the new audio, meaning that the identified portion of the new audio 405 starting at 55 seconds and running for 5 seconds until it reaches the 60 second mark does not exceed the predefined threshold time duration of 10 seconds. Accordingly, as the threshold monitoring module 425 determines that the portion of the new audio 405 of with a time duration of 5 seconds does not exceed a predefined threshold time duration of 10 seconds, then the threshold monitoring module 425 determines that no further operations are to be performed.

Upon encoding of the pancake data, the audio encoder 430 generates the pancake data file 435. In certain applications, data compression is employed on the pancake data for bandwidth efficiency and decreased upload times. For example, the pancake data is compressed to generate pancake data audio files that may be encoded in MP3 or OGG Vorbis formats, which preserve high quality while decreasing file size. In one embodiment, system 200 may use a time format other than seconds for encoding a pancake of a specific length, for example, every 8 beats, every 5 seconds, or using Society of Motion Picture and Television Engineers (SMPTE) time, or any other format appropriate for storing timecode data.

Returning to FIG. 3, step 345 of process 300 stores the generated pancake data file 435. The API 220 may be accessed and information about the pancake data may be uploaded to the data storage 210, where such information may include, as synchronization data, the time range where the pancake data file 435 was created (e.g., from 55 seconds to 60 seconds, with a total of 5 second duration). The new pancake data file 435 may be formatted into a music data file, e.g., an MP3 or OGG file, and provided to the API 220 for the purposes of storing the pancake data file 435 in cloud data storage 210, or memory, on the server 110 so as to be shared with other collaborators in the same session. It is to be understood that the pancake data file 435 may comprise the entire length of the musical composition based on the percentage of new audio that is different from the stored audio within the musical composition storage 415. In other words, the updated section of stored audio need not be limited to the 5 second examples described above.

In an embodiment, system 200 may upload a pancake data file directly to cloud data storage 210 (e.g., server 110), bypassing the need to communicate through API 220. Cloud data storage 210 may be a database that stores all the generated pancake data files. Such an arrangement may reduce bandwidth requirements and may eliminate a “man-in-the-middle” issue, as long as those files arrive at cloud data storage 210 and the guest DAWs 230b-230c, directly.

At step 350 of process 300, the server 110 may, upon storing the pancake data file 435, transmit the pancake data file 435 directly to all composers including host composer devices DAW 230a and guest composer devices 230b-c connected in the same. Such an implementation may require incoming data connections at DAWs 230a-c, such as Bluetooth, a local connection over wireless network, a USB connection, or any other wired or wireless connections over which transmission can be achieved.

At step 355 of process 300, the server 110 merges identified musical input data, also referred to as pancake data files 435, with musical input data of stored musical compositions. The server 110 may utilize the API 220 to monitor which of the pancake data files 435 contain the latest musical information and may transmit only the most recent pancake data files 435. By way of example, upon storing a pancake data file named “A”, the server 110 may determine if there is an older version of the pancake data file A that is previously stored in the musical composition storage 435. If there is an older version of the pancake data file named “Z”, the server 110 determines that pancake data file A is the latest version of musical piece, as it is generated after pancake data file Z was generated. The age of the musical input data can be determined according to associated synchronization data that includes a corresponding time stamp. The time stamp indicates the time pancake data file was generated. Accordingly, server 110 compares a first time stamp, by way of example, 2:30 pm on Jun. 5, 2020 associated with pancake data file A with a second time stamp, by way of example, 4:30 pm on May 5, 2020 associated with pancake data file Z. Based on the comparison, server 110 determines that pancake data file A is the latest version of musical input data as it is generated after pancake data file Z.

In another embodiment, step 355 of process 300 includes merging, by the client software at the DAWs 230a-c, stored musical input data with updated musical input data, also referred to as pancake data files 435, based on monitoring for updates to stored musical input data of a musical composition. For instance, identification of the update may be performed by the server 110 or by the client software, of DAW, and the client software can perform the merging of the musical pieces based on the identification of an update within the musical piece.

The merging stored musical input data is further explained, by way of example, with reference to first pancake data file “pancake 1” stored in the musical composition storage 415. The “pancake 1” is part of a musical composition, or, for example, “Song 1”. “Song 1” has duration of 4 minutes and 30 seconds. Further, by way of example, “pancake 1” contains audio data from 0 seconds to 60 seconds of “Song 1”, which has a duration of 4 minutes and 30 seconds. A newer stored pancake data file, by way of example, “pancake 2”, also associated with “Song 1”, contains audio data from 55 seconds to 60 seconds of “Song 1” that has a duration of 4 minutes and 30 seconds. In this example, the API 220, based on predefined instructions, may enforce that the ultimate musical composition contains a combination of both pancake data files i.e. “pancake 1” and “pancake 2”. By merging older pancake data files with newer ones, people listening to the session will hear a merged result that contains the combined latest audio, even if the audio was not recorded continuously in one take. In the above example, “pancake file 2” will replace the audio portion of 55 seconds to 60 seconds, by replacing corresponding portion of 55 seconds to 60 seconds from “pancake file 1” that contains audio data from 0 seconds to 60 seconds. A smaller pancake data file lying over a larger pancake data file will obscure a small portion of the larger pancake data file. Thus, the pancake metaphor is used. This merging action of multiple audio pancake data files can be performed by the server 110, the host composer device 230a, guest composer devices 230b-c, or the API 220, itself.

In an embodiment, the server 110 stores pancake data file 435 in the musical composition storage 415 with a corresponding unique identifier of the an audio file. In an example, this may be audio file 1 having a time stamp which includes date, time, and day the pancake data file 435 was generated. This unique identifier may be a number, or text that corresponds to the audio file. Accordingly, in the future, the server 110 stores all other pancake data file 435 associated with audio file 1 with the same unique identifier. As a result, upon storing each of the pancake data file 435, the server 110 will identify all the pancake data files associated with the audio file 1 unique identifier and, based on the time stamp of the pancake data file, determine the latest version of the pancake data file to be merged with an older version of a pancake data file, as explained earlier.

In step 360 of process 300, and assuming the server 110 performs the merge at step 355 of process 300, the server 110 transmits the merged version of the musical composition to all composers, including host composer devices DAW 230a and guest composer devices 230b-c connected in the same session. Such an implementation may require incoming data connections at DAWs 230a-230c, such as Bluetooth, a local connection over wireless network, a USB connection, or any other wired or wireless connections over which transmission can be achieved.

In an embodiment, the guest composer devices DAWs 230b-230c download information about the musical collaboration session from the API 220, which was originally provided by the host composer device DAW 230a. This information may contain metadata, or synchronization data, associated with first musical input data, which includes a length of a song, a name of the song, how many channels of audio and MIDI the song contains, a tempo of the song, the key and scale of the song, the time signature associated with the song, and other similar information. In a situation where the guest composer devices DAWs 230b-c are set to a wrong tempo, the DAWs 230b-c software may, based on the synchronization data, warn guest users that the tempo (or other metadata) must be changed to match the tempo of the host composer device DAW 230a. In certain embodiments, pancake data files 435 having the incorrect tempo may be automatically filtered out from consideration. This avoids situations where host composer device DAW 230a and guest composer devices DAWs 230b-c can go off-time from each other. In addition to the song metadata/synchronization data, each pancake data file, or each audio channel may also contain additional communication such as comments, emojis, votes, and conversation threads to enable participants to discuss their work with each other. In certain embodiments, a rating system may dictate which pancake data file is placed atop other pancake data file. In yet another embodiment, the musical collaboration session initiated at step 310 of process 300 may present a user interface 500 as illustrated in FIGS. 8A-8D.

With reference now to FIG. 5, a description of process 500 is provided. Process 500 includes appending a new channel of musical input data to an existing musical composition. Process 500 may be performed by the server 110.

At step 505 of process 500, the server 110 may obtain a musical composition from the musical composition storage 415. The musical composition may include, at least, first musical input data pf a first channel of the musical composition. The first channel may be an audio channel such as a “guitar” channel.

At step 510 of process 500, the server 110 may receive second musical input data associated with a second channel of the musical composition. The second channel may be an audio channel. The second musical input data can be provided by a client device such as any one of the host composer DAW 230a and the guest composer DAWs 230b-c. The second audio channel may not be previously present in the musical composition.

At step 515 of process 500, and appreciating that the second musical input data is associated with a second audio channel that is different from the first audio channel and not present in the musical composition, the server 110 may generate a data block. The data block may include pancake data associated with the second musical input data and synchronization data. In an embodiment, the synchronization data may include timing data associated with the second musical input data, the timing data allowing the pancake data to be located within the timeline of the musical composition and relative to the first musical input data of the first audio channel. The synchronization data may also include metadata associated with the second musical input data, such as tempo and the like, as described above.

At step 520 of process 500, the data block generated at step 515 of process 500 can be transmitted to memory, or another storage device, at the server 110. In an embodiment, the memory or the other storage device may be integral with the musical composition storage 415.

In an embodiment, and following step 520 of process 500, processes similar to step 355 of process 300 may be performed by the server 110 in order to merge the pancake data associated with the second musical input data of the second audio channel and the first musical input data of the first audio channel of the musical composition. In another embodiment, and following step 520 of process 500, the data blocks stored at the memory may be accessible to any of the host composer DAW 230a and the guest composer DAWs 230b-c. As a result, each data block can be merged with the larger musical composition at the one of the host composer DAW 230a and the guest composer DAWs 230b-c. In this way, only the data block need be downloaded to each client device executing the host composer DAW 230a and the guest composer DAWs 230b-c, eliminating the need to download an entire musical composition at each update.

With reference now to FIG. 6A, a description of process 600 is provided. Process 600 includes determining if new musical input data of a given channel includes audio that is unique from corresponding musical input data within the musical composition stored in the musical composition storage 415. Process 600 may be performed by the server 110.

At step 605 of process 600, and in view of FIG. 5, third musical input data associated with the first channel may be received by the server 110. The first channel may be the first audio channel and the third musical input data may correspond to at least a portion of the first musical input data associated with the first audio channel.

At sub process 610 of process 600, the server 110 determines whether a portion of the third musical input data is different from a segment of the corresponding portion of the first musical input data. Sub process 610 of process 600 will now be described with respect to FIG. 6B.

In an embodiment, and at step 611 of sub process 610, the server 110 is configured to calculate a correlation value between the portion of the third musical input data and the segment of the corresponding portion of the first musical input data. A corresponding portion of the first musical input data can be defined as portions of the first musical input data and the third musical input data having similar timings within the musical composition, as defined by synchronization data associated therewith. In an example, the correlation value may be calculated for an entire length of the third musical input data that corresponds to a segment of the first musical input data, for successive segments of the length of the third musical input data that corresponds to segments of the first musical input data, or for another duration of the musical composition wherein there are corresponding time sequences between the third musical input data and the first musical input data. A comparison of the calculated correlation value with a threshold correlation value, the threshold correlation value being selected so as to determine the compared musical input data are sufficiently different, indicates whether the newly received third musical input data is different from the first musical input data. When determined to be different, or relatively uncorrelated, process 600 may process to step 610. When determined to be similar, sub process 610 of process 600 ends.

In an embodiment, and following determining, at step 611 of sub process 610 the portion of the third musical input data is different from the segment of the corresponding portion of the first musical input data, sub process 610 may proceed to step 612, wherein a time length of the different portion of the third musical input data is evaluated relative to a time length threshold. This evaluation may be a comparison of the time length to the time length threshold, the evaluation serving as a second evaluation of the correlation comparison at step 611 of sub process 610. For instance, if the time length threshold is 3 seconds, a 2 second portion of the third musical input data, determined to be different at step 611 of sub process 610 would not be considered different, for long enough, at step 612, and thus sub process 610 would end. Of course, if the portion of the third musical input data that is different from the segment of the corresponding portion of the first musical input data has a time length of 20 seconds, step 612 would determine the difference to be legitimate and would pass the result to step 620 of process 600.

Returning to FIG. 6A, when the portion of the third musical input data is determined to be different at sub process 610 of process 600, a delta data block can be generated at step 620 of process 600. The delta data block can be based on the portion of the third musical input data that is different from the segment of the corresponding portion of the first musical input data and can include pancake data corresponding to the portion of the third musical input data as well as synchronization data identifying timing of the contribution to the musical composition.

The delta data block generated by the server 110 at step 620 of process 600 can be transmitted to memory, or other storage device, of the server 110 at step 625 of process 600. In an embodiment, the memory or the other storage device may be integral with the musical composition storage 415.

In an embodiment, and following step 625 of process 600, processes similar to step 355 of process 300 may be performed by the server 110 in order to merge the pancake data associated with the third musical input data of the first audio channel and the first musical input data of the first audio channel of the musical composition.

In another embodiment, and following step 625 of process 600, the delta data block stored at the memory may be accessible to any of the host composer DAW 230a and the guest composer DAWs 230b-c. As a result, the delta data block can be merged with the larger musical composition at the one of the host composer DAW 230a and the guest composer DAWs 230b-c. In this way, only the delta data block, including the pancake data and the synchronization data, need be downloaded to each client device executing the host composer DAW 230a and the guest composer DAWs 230b-c, eliminating the need to download an entire musical composition at each update.

FIG. 7A describes a flow diagram wherein a host composer DAW 230a provides synchronization data dictating parameters of the musical composition to guest composer DAWs 230b-c. Process 730 can be performed by the server 110.

At step 735 of process 730, the server 110 receives instructions regarding synchronization data dictated by the host composer DAW 230a. The instructions may include a length of a musical composition, a name of the musical composition, how many channels of audio and MIDI the musical composition may contain, a tempo of the musical composition, the key and scale of the musical composition, the time signature associated with the musical composition, and other similar information. The server 110 may generate, at step 740 of process 730, a host data block including the synchronization data. At step 745 of process 730, the generated host data block may be transmitted to the memory, or other storage device, of the server 110 in order to be accessible to the guest composer DAWs 230b-c.

FIG. 7B describes a flow diagram wherein a guest composer DAW 230b-c transmits a request to access the musical composition. Process 750 of FIG. 7B may be performed by the server 110.

At step 755 of process 750, the server 110 may receive a request from a guest composer DAW 230b-c to access the musical collaboration. The host composer DAW 230a may evaluate the request or the server 110 may evaluate the request in view of a host data block (described in FIG. 7A) in order to determine what permissions the guest composer DAW 230b-c is allowed. For instance, as in FIG. 7B, the requesting guest composer DAW 230b-c may only be allowed to view and play-back the musical composition on their device. Accordingly, at step 760 of process 750, the server 110 transmits restricted musical composition data to the guest composer DAW 230b-c. The restricted musical composition data may include a play-back only version of the musical composition. Such a version of the musical composition allows for muting, adjusting volume, and other play-back features of the DAW, but does not reflect any changes made by the guest composer DAW 230b-c to the server 110 to be incorporated into the musical composition presently being collaborated on. This allows users that are not contributing to a channel of the musical composition to be able to view and/or participate in the making of the music.

Of course, even though the guest composer DAW 230b-c may not be able to ‘edit’ the musical composition, any updates made by ‘editing’ members of the collaboration will be realized at the guest composer DAW 230b-c in the same way as described above.

With reference now to FIG. 8A through FIG. 8D, and in view of FIG. 3, user interface 800 illustrates a musical collaboration session hosted by host user 805 and including guest users 810. Corresponding to each of the users the user interface illustrates a second musical input data received. Further, user interface 800 on FIG. 8B illustrates a chat window 820 presented that allows participants of the musical collaboration session, which includes host user associated with DAW 230a and guest users 810 associated with composer devices DAWs 230b-c, to communicate with each other by send messages and emojis.

The plugins associated with host composer device DAW 230a and guest composer devices DAWs 230b-c may be connected, either directly or via the API 220. Further, when a new pancake data file is stored to the cloud at step 345 of process 300, the server 110 generates a signal to send to the host composer device DAW 230a and guest composer devices DAWs 230b-c, notifying that a new pancake data file is available. In another embodiment, when a new pancake data file is stored to the cloud, the server 110 applies the new pancake data file to the existing musical composition within the musical composition storage 415, overlaying any older portions of audio from previous pancake data files (as explained above). As mentioned previously, this merging action of combining multiple pancakes into one “latest” audio output can be performed by the server 110, host composer device DAW 230a, and/or guest composer devices DAWs 230b-c.

In the event that the guest composer devices DAWs 230b-c are not logged into the musical collaboration session at the time a pancake data file 435 is generated by host composer device DAW 230a, then the guest composer devices DAWs 230b-c may be notified by an in-app notification, a text message, email, or another communication technique to indicate to them that the host composer device DAW 230a has created new pancake data file 435 and uploaded it to the cloud storage (e.g., musical composition storage).

In an embodiment, smooth collaboration is enabled by the automatic capture of audio input data on both the host composer device DAW 230a and the guest composer devices DAWs 230b-c sides of the collaboration. As hosts user 805 and guests users 810 scroll through their projects in the user interface 800 and hit “play” 815 to hear the at least a portion of the musical composition, any new changes are automatically captured and encoded to generate new pancake data files 435. The new pancake data files 435 can be uploaded and shared with other participants in the musical collaboration session.

In an embodiment, it is possible for the host composer device DAW 230a and the guest composer devices DAWs 230b-c to mark their respective contributions to the musical composition as private (for the host's eyes only) or as public (for everyone to hear). In marking a musical contribution as public, other participants are able to hear the work directly.

Embodiments of the present disclosure described herein allow the host composer device DAW 230a and the guest composer devices DAWs 230b-c to work together in real-time but independently. Further, embodiment of the present disclosure described herein allow the host composer device DAW 230a and the guest composer devices DAWs 230b-c to make changes to their audio inputs without affecting what guest composer devices DAWs 230b-c see on their user interface 800 and without interfering with the guest composer devices DAWs 230b-c recording their own versions and additions during the musical collaboration session. For example, the host composer device DAW 230a may be working, as shown in FIG. 8C, on chords and melodies on the guitar, a first channel of the musical composition, while the guest composer devices DAWs 230b-c are recording vocals, an at least second channel of the musical composition. Since this approach allows both the host composer device DAW 230a and guest composer devices DAWs 230b-c to co-exist, it replicates the approach to collaboration amongst musicians working face to face. It solves the problem where two musicians cannot use one computer because they cannot attach two keyboards, two mice, or two touch devices. Instead, each musician in this approach has their own computer, and can control the channels of audio independently and create new parts, while having an easy way to sync them together. Moreover, local DAW playback of the collaborative musical piece can be performed using synced audio from the downloaded inputs from guest composer devices DAWS 230b-c as well as local adjustments made via any one of the composer devices involved in the collaboration.

In an embodiment, at step 320 of process 300, along with receiving a selection of a channel from host composer device DAW 230a, the server 110 may also receive a criterion of a time range associated with a second musical input data file that one of a guest composer device DAWs 230a-c may upload. For example, the second musical input data may be provided by respective guest composer devices DAWs 230b-c and may have a duration of less than 60 seconds. In another embodiment, the guest composer devices DAWs 230b-c contribute ideas back to the host composer device DAW 230a. Once the guest composer devices DAWs 230b-c are connected to a musical collaboration session, the guest composer devices DAWs 230b-c can click a respective button called “Upload a Take” on user interface 800. The “Take” may be an audio file containing musical input data that fit into a time range specified by the host composer device DAW 230a. For example, all music from 0 seconds to 60 seconds may be the “Take”. The guest composer devices DAWs 230b-c may label each take with a name, ex: “Great vocals for the song”, or append additional metadata to it, such as their own user name, their contact information, and any notes that may be relevant to the creative process.

In an embodiment, all audio captured from guest composer devices DAWs 230b-c may be auto-uploaded as musical input data to the musical collaboration session without requiring the user to click an “upload” button.

In an embodiment, once a pancake data file associated with guest composer devices DAWs 230b-c is uploaded to the API 220, the host composer device DAW 230a may be notified that a new pancake data file, also referred to as a new audio take, is available. The host composer device DAW 230a can open their own session, and scroll/tab through the list of available audio submissions, or musical input data submissions, from different guest composer devices DAWs 230b-c. Those submissions may be optionally sorted by user name, by date of upload, by comments, or any other metadata column to identify who created the take and when. Further, by selecting and loading a take, the host composer device DAW 230a will be able to hear the audio coming from their own speakers. Selecting a take allows for both playback and the ability to drag the take onto the user interface 800, from where the pancake data file is stored, as an exported audio file. At the host composer device DAW 230a discretion, the same take could become part of the official output that gets encoded into pancakes and sent to any other guest composer devices DAWs 230b-c. This approach allows hierarchical host-guest synchronization, followed by guest composer devices DAWs 230b-c contributing an idea that gets auditioned by the host composer device DAW 230a, and possibly distributed to other guests as part of the host's role in deciding what audio parts are distributed everyone in the session.

Guest-guest collaboration is also possible. In an embodiment, guest composer device DAW 230b can share takes with guest composer device DAW 230c, bypassing the host composer device DAW 230a oversight and allowing direct collaboration inside the same session. In an embodiment, and at the guest's discretion, it may be possible to mark a take as “available to all guests”, or “available to host only”, allowing a permissions-based, limited amount of sharing between guest composer devices DAWs 230b-c and host composer device DAWs 230a.

In addition to distributing audio files, it is common amongst musicians to collaborate using MIDI format, introduced above, which allows musical notes to be passed between musicians instead of merely audio. MIDI is the digital equivalent to sheet music. MIDI allows the producer to change what instrument is playing the sound of the melody captured by the musical notes. For example, the same MIDI file can be played using a digital synth, a digital bass, or a sampled violin. MIDI files are more flexible than audio files because they allow the sound designer to change the sound while keeping the same musical pitch and rhythm of the original composition.

To exchange MIDI files, the following augmentation to the original idea may be implemented. In addition to having regular “audio effect” software that can be put on any channel, embodiments of the technology may create “shell host” software that can be added to a MIDI channel as an instrument. This software has a simple user interface to select which musical instrument should be chosen to perform the audio. This instrument could be another third-party plugin, such as Sylenth. Adding this “shell host” software to the DAW would result in MIDI notes being input into the plugins 240a-c, and audio coming out, both of which can be captured as MIDI pancake data files and encoded by the audio encoder at step 430 of process 400 and uploaded to the cloud.

In an example, a visualization of this process is shown in FIG. 8D and with reference to FIG. 4. A MIDI clip may be received by DAW 230a. The MIDI clip is input into the Shell Software, which may be used to select ‘Kontakt 5’ as the instrument 870. The MIDI input is captured and encoded as MIDI pancake data file by the Shell Software. MIDI pancake data is received by the third-party software hosted inside the shell software to synthesize audio as if it was originally performed using the ‘Kontakt 5’. The third-party software captures the audio output of the third-party software and encodes it as an audio pancake data file. In this way, the MIDI and the audio are being captured. The audio pancake data file is passed back to the DAW 230a resulting in a simple workflow for musicians who already use instruments in their DAW 230a.

In an embodiment, the shell software is added at the start of the sound design chain, more plugins 240a-c, such as reverb and echo, may be added in the middle of the chain, and finally, one more regular session software instance may be added at the end to capture the final audio signal with all the modifications. This would result in three pancake data files being generated automatically: (1) the MIDI pancake, (2) the audio pancake immediately following the synthesis of the sound inside the shell plugin by the third-party plugin, and (3) the sound design at the end of the entire chain after all other effect plugins have been applied. All three segments may be shared with guest users.

In an embodiment, a “read receipt” style monitoring may be performed on all takes to make sure that the target audience (guest composer devices DAWs 230b-c and host composer device DAWs 230a) has heard it. For example, if the guest composer devices DAWs 230b-c uploaded a take to the host composer device DAWs 230a, the API 220 can be aware of whether the host composer device DAWs 230a has heard that take. If not, the host composer device DAWs 230a may be notified that a new take is waiting.

In an embodiment, a pancake data file 435 can be emailed or otherwise sent to the guest composer devices DAWs 230b-c and host composer device DAWs 230a to hear the resulting audio file as an attachment. All the pancake data files can be merged together and the final output can be mixed for an easy listening on the go, for example, in an email attachment or inside a mobile app.

The present disclosure allows multiple software instances to exist inside the same session. The host composer device DAWs 230a can add a “kick” software instance on the kick stem, a “snare” software instance on the snare stem, etc. The guest composer devices DAWs 230b-c can choose which of those stems to enable/disable when listening to the session inside the guest composer devices DAWs 230b-c. This selective mute/solo/volume editing approach allows the guest composer devices DAWs 230b-c to replace an element already created for the host composer device DAW 230a, for example, the guest composer devices DAWs 230b-c may suggest a better snare pattern on the “snare” channel and may upload that result back to the host composer device DAW 230a for consideration.

It is to be noted that the present disclosure describes operations of the server 110 that can be performed at the server 110, within DAWs 230a-c, or as a combination thereof. Moreover, the functionality described in plugins 240a-c for hosts and guests can be added to the DAWs 230a-c, themselves, giving users an easy way to toggle sharing on each channel.

In an embodiment, host composer device DAW 230a may transmit, to the server 110, a session termination request to terminate the session initiated during step 310 of process 300. The session termination request may be transmitted anytime between step 315 and step 360 of process 300 of FIG. 3. Upon the server 110 receiving the session termination request, the communication channel between the host composer device DAW 230a and the server 110 may be terminated by utilizing SIP protocols.

In an embodiment, any guest composer devices DAW 230b-c may transmit, to the server 110, a session termination request to terminate the session initiated during step 330 of process 300. Upon the server 110 receiving the session termination request, the communication channel between the guest composer devices DAW 230b-c that sent the termination request and the server 110 may be terminated by utilizing SIP protocols.

In an embodiment, host composer device DAW 230a may transmit, to the server 110, a session termination request to terminate the session of any of the guest composer devices DAW 230b-c initiated during step 330 of process 300. Upon the server 110 receiving the session termination request, the communication channel between the guest composer devices DAW 230b-c that the host composer device 230a has identified in the termination request and the server 110 may be terminated by utilizing SIP protocols.

A computer program, which may also be referred to or described as a program, software, a software application, a module, a software module, a script, or code, can be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data, e.g., one or more scripts stored in a markup language document, in a single file dedicated to the program in question, or in multiple coordinated files, e.g., files that store one or more modules, sub-programs, or portions of code. A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this specification can be performed by one or more programmable computers executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit).

Computers suitable for the execution of a computer program include, by way of example, general or special purpose microprocessors or both, or any other kind of central processing unit. Generally, a central processing unit will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a central processing unit for performing or executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device, e.g., a universal serial bus (USB) flash drive, to name just a few. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.

To provide for interaction with a user, embodiments of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's device in response to requests received from the web browser.

Embodiments of the subject matter described in this specification can be implemented in a computing system that includes a back-end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front-end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (LAN) and a wide area network (WAN), e.g., the Internet.

The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some embodiments, a server transmits data, e.g., an HTML page, to a user device, e.g., for purposes of displaying data to and receiving user input from a user interacting with the user device, which acts as a client. Data generated at the user device, e.g., a result of the user interaction, can be received from the user device at the server.
