Computer systems and methods are provided for processing audio queries. An electronic device receives an audio clip and performs a matching process on the audio clip. The matching process includes comparing at least a portion of the audio clip to a plurality of reference audio tracks and identifying, based on the comparing, a first portion of a particular reference track that corresponds to the audio sample. Upon identifying the matching portion, the electronic device provides a backing track for playback which corresponds to the particular reference track, and an initial playback position of the backing track.

The teachings described herein are generally directed to a system, method, and apparatus for separating and mixing tracks within music. The system can have a video that is synchronized with the variations in the musical tempo through a variable timing reference track designed and provided for a user of the preselected performance that was prerecorded, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected performance.

A device for processing audio signals, including: first and second input units providing first and second input signals of first and second audio tracks, a decomposition unit to decompose the first input audio signal to obtain a plurality of decomposed signals, a playback unit configured to start playback of a first output signal obtained from recombining at least a first decomposed signal at a first volume level with a second decomposed signal at a second volume level, such that the first output signal substantially equals the first input signal, and a transition unit for performing a transition between playback of the first output signal and playback of a second output signal obtained from the second input signal. The transition unit has a volume control section adapted for reducing the first and second volume levels according to first and second transition functions.

A method for processing audio data, comprising providing song identification data identifying a particular song from among a plurality of songs or identifying a particular position within a particular song, loading intermediate data associated with the song identification data from a storage medium or from a remote device. The method also comprises obtaining input audio data representing audio signals of the song as identified by the song identification data. The audio signals comprise a mixture of different musical timbres, including at least a first musical timbre and a second musical timbre different from said first musical timbre. The method comprises combining the input audio data and the intermediate data with one another to obtain output audio data. The audio data represent audio signals of the first musical timbre separated from the second musical timbre.

A method and system for automatically transcribing an audio source, e.g. a WAV file or live feeds, into a computer-readable code, e.g., enhanced MIDI, are provided, specifically and limited to solving a central problem that has not been solved elsewhere: it takes a large sampling window, say from a fifth of a second to a full second for typical music, to extract many music perceptual parameters of interest, yet that transcription also needs to maintain synchronization with the source music, with the time resolution of that synchronization about a sixteenth of a second.

A chord identification method selects from among a plurality of chord identifiers a chord identifier that corresponds to an attribute of a piece of music represented by an audio signal, where the plurality of chord identifiers corresponds to respective ones of a plurality of attributes relating to pieces of music; and identifies a chord for the audio signal by applying a feature amount of the audio signal to the selected chord identifier.

A music beat point detection method includes: performing a frame processing on a music signal to obtain a frame signal; obtaining a power spectrum of the frame signal; performing sub-band decomposition on the power spectrum, and decomposing the power spectrum into at least two sub-bands; performing a time-frequency domain joint filtering on a signal of each sub-band according to a beat type corresponding to each sub-band; obtaining a to-be-confirmed beat point from the frame signal of the music signal according to a result of the time-frequency domain joint filtering; and obtaining a beat point of the music signal according to a power value of the to-be-confirmed beat point.

An operator of a digital audio workstation (DAW) application is able to assign individual tracks of a DAW session for export to specific players within a musical score of a scorewriter application. The DAW operator associates each track with a player identifier, which is retained in association with an interoperable format file generated by the export process. When the scorewriter imports such a file, it extracts the player identifier and uses it to map the track to a scored instrument. The mapping may also depend on a scorewriter arrangement of players for the instruments. The DAW operator may assign multiple tracks representing a given instrument played with different techniques to a single instrument part in a score. The playing techniques for the instruments are also associated with the tracks and may be parsed by the scorewriter to annotate the score with the corresponding notations.

Provided are a method and device for processing a music file, a terminal and a storage medium. The method comprises: in response to a received sound effect adjustment instruction, acquiring a music file, the adjustment of which is indicated by the sound effect adjustment instruction; carrying out vocals and accompaniment separation on the music file to obtain vocal data and accompaniment data in the music file; carrying out first sound effect processing on the vocal data to obtain target vocal data, and carrying out second sound effect processing on the accompaniment data to obtain target accompaniment data; and synthesizing the target vocal data and the target accompaniment data to obtain a target music file.

Methods and systems are disclosed to facilitate creating the sensation of vibrotactile movement on the body of a user. Vibratory motors are used to generate a haptic language for music or other stimuli that is integrated into wearable technology. The disclosed system in certain embodiments enables the creation of a family of devices that allow people such as those with hearing impairments to experience sounds such as music or other input to the system. For example, a “sound vest” or other wearable array transforms musical input to haptic signals so that users can experience their favorite music in a unique way, and can also recognize auditory or other cues in the user's real or virtual reality environment and convey this information to the user using haptic signals.
