In general, this disclosure concerns media streaming. Among other things, the present disclosure presents a first media item for streaming from a computer server system to a media device. The first media item has an audio format. Furthermore, the first media item comprises a number of media segments, wherein each one of the number of media segments is identifiable by a media segment identifier. Still further, one or several of the number of media segments is/are associated with a respective second media item corresponding to a respective media segment identifier. The second media item(s) typically has/have a media format other than audio.

A system and methods for collaborating on a musical composition over a communication network, the system having processing circuitry that obtains the musical composition stored within a data storage device of the system, the musical composition including a first musical input data associated with a first channel, receives, via the communication network, second musical input data from a client device, the second musical input data being associated with a second channel, generates a data block based on the received second musical input data, the generated data block including synchronization data associated with the second musical input data relative to at least a portion of the musical composition, and transmits the data block to memory, the memory being accessible via the communication network to the client device and other client devices that are collaborating on the musical composition.

The present disclosure provides a method for mixing audio, pertaining to the technical field of multimedia. The method includes: after acquiring an audio material to be mixed, determining a beat feature of a target audio, performing beat adjustment on the audio material based on the beat feature of the target audio; and performing audio mixing on the target audio based on the audio material adjusted by the beat adjustment.

A collaboration system, a collaboration method and a computer-readable medium for realizing online offsite synchronous ensemble are provided, in which before performing a synchronous ensemble of the same song, a controlling device and a controlled device respectively pre-download a music score of the same song from a servo device, so that the controlling device sets a note starting position of the music score when the same song is performed, and then the controlling device and the controlled device synchronize the note starting position of the music score of the same song, such that when the controlling device executes a start playing command of the music score of the same song, the controlling device and the controlled device start to play the music score of the same song note by note synchronously according to the note starting position of the music score of the same song.

Visual effects, including augmented reality-type visual effects, are applied to audiovisual performances with differing visual effects and/or parameterizations thereof applied in correspondence with computationally determined audio features or elements of musical structure coded in temporally-synchronized tracks or computationally determined therefrom. Segmentation techniques applied to one or more audio tracks (e.g., vocal or backing tracks) are used to compute some of the components of the musical structure. In some cases, applied visual effects are based on an audio feature computationally extracted from a captured audiovisual performance or from an audio track temporally-synchronized therewith.

User interface techniques provide user vocalists with mechanisms for forward and backward traversal of audiovisual content, including pitch cues, waveform- or envelope-type performance timelines, lyrics and/or other temporally-synchronized content at record-time, during edits, and/or in playback. Recapture of selected performance portions, coordination of group parts, and overdubbing may all be facilitated. Direct scrolling to arbitrary points in the performance timeline, lyrics, pitch cues and other temporally-synchronized content allows user to conveniently move through a capture or audiovisual edit session. In some cases, a user vocalist may be guided through the performance timeline, lyrics, pitch cues and other temporally-synchronized content in correspondence with group part information such as in a guided short-form capture for a duet. A scrubber allows user vocalists to conveniently move forward and backward through the temporally-synchronized content.

A mechanism that enables the real-time provision of content according to a user's body movement is provided. An information processing apparatus includes a reproduction control unit (43) that controls reproduction of content on the basis of a result of prediction of a timing of a predetermined state in traveling movement of a user, which is predicted on the basis of sensor information regarding the traveling movement.

This video control device includes: a detection unit that detects a beat timing of audio; and a control unit that updates a display mode of a video on the basis of the beat timing and change information indicating a change in a display mode of a video displayed on a display device.

The present disclosure relates to a method and device for audio generation. The method includes: obtaining a target rhythm, a target verse melody and a target chorus melody; configuring the target rhythm as a first audio track, the target verse melody as a second audio track, and the target chorus melody as a third audio track; generating a target audio by aligning start playing time of the first audio track, the second audio track and the third audio track to beat occurrence time of a first beat, a second beat and a third beat in a first metronome data respectively.

A system and method to identify a digital representation of a first musical composition including a set of musical blocks. A set of parameters associated with source content are identified. In accordance with one or more rules, one or more of the set of musical blocks of the first musical composition are modified based on the set of parameters to generate a derivative musical composition. An audio file including the derivative musical composition is generated.
