A device 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 decomposed signals, a playback unit to start playback of a first output signal obtained from recombining at least first and second decomposed signals at first and second volume levels, respectively, 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 is adapted for reducing the first/second volume levels according to first/second transition functions. The device includes an analyzing unit to analyze an audio signal to determine a song part junction between two song parts. The transition time interval of at least one of the transition functions is set such as to include the song part junction.

An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

Systems and methods for providing audio-file loop-playback functionality are provided. The system includes a processor that performs a method including setting a playback loop start-point based on a first selection of a button; setting a loop end-point, associating a loop with an audio file, and entering into the loop based on a second selection of the button; and exiting the loop based on a third selection of the button. Associating the loop with the audio file includes adding metadata to the audio file. The metadata associates the loop with a button. The method includes reentering the loop based on a fourth selection of the button and exiting the loop based on a fifth selection of the button.

A driving sound library provides driving sounds classified in various themes to a user by analyzing frequency characteristics and temporal characteristics of sound sources classified into categories and determining a chord corresponding to each sound source based on the frequency characteristics and the time characteristics. Modulated sound sources in which each sound source is modulated are generated by applying a chord corresponding to each sound source. The driving sound sources are generated using the sound sources and the modulated sound sources as input data. Pitches of the driving sound sources are then changed based on the driving sound sources and engine sound orders corresponding to an engine RPM of a preset range. Scores for each theme for the driving sounds are generated.

A system and method for operating and performing a remotely networked virtual musical instrument. A client transmits musical control data to a remote server over the network, encompassing a digital music engine and digitally sampled virtual musical instruments. In return, the client consumes, synchronizes, and mixes the combined server playback stream from the network of the fully expressive and interactive musical performance with zero audible latency.

An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display, a memory storing audio files for playback when the playback is triggered by a signal received from a pad, and one or more processors coupled to the electronic display and the memory. The processors are configured to play a portion of the audio files when the playback is triggered by the signal received from the one or more electronic-drum pads. The processors are also configured to display, on the display, a user interface for an application, which includes a waveform associated with recorded audio. The processors are also configured to display, on the display, tempo gridlines with a tempo-gridline spacing over the waveform. The module includes a control for adjusting the tempo-gridline spacing. The control is a wheel and is actuated by a rotation of the wheel.

A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.

A method for processing music audio data, including providing input audio data representing a first piece of music comprising a mixture of musical timbres. The method also includes decomposing the input audio data to generate at least first-timbre decomposed data representing a first timbre selected from the musical timbres of the first piece of music, and second-timbre decomposed data representing a second timbre selected from the musical timbres of the first piece of music. The method also includes applying a transport control to obtain transport controlled first-timbre decomposed data. The method also includes recombining audio data obtained from the transport controlled first-timbre decomposed data with audio data obtained from the second-timbre decomposed data to obtain recombined audio data.

A device is provided for capturing vibrations produced by an object such as a musical instrument such as a drum head of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

An acoustic device includes an audio recording playback unit, an analysis unit, and an acoustic effect imparting unit. The audio recording playback unit records and plays back string independent acoustic signals for each string independent acoustic signal. The string independent acoustic signals respectively correspond to different strings of a stringed instrument and being independent from each other. The analysis unit analyzes at least one string independent acoustic signal from among the recorded string independent acoustic signals. The acoustic effect imparting unit imparts an acoustic effect to the at least one string independent acoustic signal for each string independent acoustic signal, based on a result of the analysis by the analysis unit.
