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 virtual instrument can manage separate static and dynamic samples for various notes that can be played by the virtual instrument. In some cases, the static samples correspond to resonance sounds recorded for an instrument and are the same for every note. However, the dynamic samples may correspond to isolated sounds that are recorded for each variation of a note that can be played. In response to a user's selection of a note on a user interface of the virtual instrument, the virtual instrument may determine a rule for layering the various static and dynamic samples for playback.

A sample counter in each channel performs counting operation at a given rate. Independently for each channel, the rate and an initial value for the counter are set, and start and stop of the counting operation of the counter are controlled, so that a partial portion of an original waveform corresponding to a count range from the set initial value to a count stop point is reproduced in the channel. A control section sets the initial values in individual ones of a set of channels, selected from among the channels, such that sample values at different sample positions of the original waveform are simultaneously retrieved in individual ones of the set of channels, and controls an overlap adder to add up the retrieved sample values, so that sample values of an audio waveform signal with a plurality of partial portions of the original waveform, partially overlapping each other are output.

A sound synthesis system is provided with a loudspeaker to project sound indicative of synthesized motor sound in response to receiving a synthesized sound (SS) signal, and a processor. The processor is programmed to: estimate motor sound based on a sensor signal indicative of sound present within a passenger compartment; identify a dominant motor harmonic of the motor sound with an amplitude and a frequency; determine an enrichment value of the motor sound; determine if the motor sound is unenriched based on a comparison of the enrichment value to an enrichment threshold value; generate at least one additional motor harmonic with a first frequency that is different than the frequency of the dominant motor harmonic in response to the motor sound being unenriched; and provide the SS signal to the loudspeaker, wherein the SS signal is indicative of the at least one additional motor harmonic.

An environmental sound generating apparatus generates an environmental sound signal representing an environmental sound that forms sound environment by being emitted. The environmental sound has at least one chain of phonemes constituted of individual phonemes which sound-emission start timings as one of attributes thereof are sequentially shifted. A plurality of subgroups are prepared each formed by combining individual plural pitches from pitches constituting a primary pitch group that is a group of phonemes musically treated as consonances if sounded simultaneously. One of the plurality of subgroups selected at random is set to each of the sections of the chain of phonemes, and each of the individual phonemes of each section of the chain of phonemes is set to a pitch selected at random from the plural pitches constituting the selected subgroup to attain hypersonic effects.

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.

This disclosure provides a transducer apparatus for an edge-blown aerophone, the edge-blown aerophone having an aerophone embouchure hole. An aerophone speaker delivers sound to a resonant chamber of the aerophone via the aerophone embouchure hole. An aerophone microphone receives, via the aerophone embouchure hole, sound in the resonant chamber. A housing provides a lip plate with a housing embouchure hole independent and separate from the aerophone embouchure hole. Breath sensors sense breath applied across the housing embouchure hole. An electronic processor, connected to the speaker, receives signals from the microphone and the breath sensors. The breath sensors provide signals indicative of breath strength. The electronic processor generates an excitation signal which is delivered as an acoustic excitation signal to the resonant chamber by the aerophone speaker. The electronic processor uses the signals it receives to determine a desired musical note which a player of the aerophone wishes to play.
