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.

Examples of wearable devices that can present to a user of the display device an audible or visual representation of an audio file comprising a plurality of stem tracks that represent different audio content of the audio file are described. Systems and methods are described that determine the pose of the user; generate, based on the pose of the user, an audio mix of at least one of the plurality of stem tracks of the audio file; generate, based on the pose of the user and the audio mix, a visualization of the audio mix; communicate an audio signal representative of the audio mix to the speaker; and communicate a visual signal representative of the visualization of the audio mix to the display.

A method and system for processing an audio stem/loop, including dividing a stem into a plurality of stem slices, classifying each of the plurality of stem slices into at least a first group or a second group and applying a stem effect, that includes replacing at least one stem slice with an all-zero stem slice, replacing at least one stem slice belonging to the first group or the second group with a stem slice belonging to the first group or the second group.

A music analysis method realized by a computer includes calculating an evaluation index of each of a plurality of structure candidates formed of N analysis points selected in different combinations from K analysis points in an audio signal of a musical piece, and selecting one of the plurality of structure candidates as a boundary of a structure section of the musical piece in accordance with the evaluation index of each of the plurality of structure candidates. N is a natural number greater than or equal to 2 and less than K, and K is a natural number greater than or equal to 2.

Examples of wearable devices that can present to a user of the display device an audible or visual representation of an audio file comprising a plurality of stem tracks that represent different audio content of the audio file are described. Systems and methods are described that determine the pose of the user; generate, based on the pose of the user, an audio mix of at least one of the plurality of stem tracks of the audio file; generate, based on the pose of the user and the audio mix, a visualization of the audio mix; communicate an audio signal representative of the audio mix to the speaker; and communicate a visual signal representative of the visualization of the audio mix to the display.

The present disclosure relates to a method of automatically preparing a MIDI file based on a target MIDI file comprising respective note information about each of a plurality of target notes and a source MIDI file comprising respective note information about each of a plurality of source notes. Each note information comprises pitch information defining a pitch of the note. The method comprises ranking the plurality of target notes based on the pitch of each target note. The method also comprises, for each of the ranked target notes, removing the pitch information from the note information of the target note. The method also comprises, for each of the ranked target notes, replacing the removed pitch information with pitch information of a corresponding source note, whereby the target note has the same pitch as the corresponding source note, forming a plurality of new notes of a new MIDI file.

Disclosed is a system and method for mutating an audio file, and more particularly, for user-trained mutation tracking and tuning of an audio file, comprising the steps of: receiving a user input, wherein the user input is at least one of an audio file; entering at least a pattern into a grid sequencer by selecting any number of squares in the grid, wherein each square represents a particular count occupancy probability at a particular count in a musical composition bar that the user prefers to render as a final output; uploading at least one ‘good’ and ‘bad’ audio file sample by the user to affect the particular count occupancy probability based on the user input and pattern; and rendering the final output comprising the mutated audio file based on the user input, pattern, and upload.

In examples, a method for generating a remixed audio sample is provided. The method may include receiving an audio portion, obtaining metadata from the received audio portion, and analyzing the metadata and generating a symbolic music representation based on the analyzed metadata. In some examples, a selection of a style asset is received and applied to the symbolic music representation. Accordingly, a remixed audio portion may be rendered based on the stylized symbolic representation. That is, metadata associated with a song or song portion may be analyzed to identify a tempo, key, structure, chord, and/or progressions, etc., such that a remixed version of the song can be provided with customized instrumental arrangements and styles.

Examples of wearable devices that can present to a user of the display device an audible or visual representation of an audio file comprising a plurality of stem tracks that represent different audio content of the audio file are described. Systems and methods are described that determine the pose of the user; generate, based on the pose of the user, an audio mix of at least one of the plurality of stem tracks of the audio file; generate, based on the pose of the user and the audio mix, a visualization of the audio mix; communicate an audio signal representative of the audio mix to the speaker; and communicate a visual signal representative of the visualization of the audio mix to the display.
