Method, device and software for controlling transport of audio data

A device for processing music audio data, comprising:

• an input unit for receiving input audio data representing a first piece of music comprising a mixture of predetermined musical timbres;
• a decomposition unit for decomposing the input audio data received from the input unit to generate at least a first decomposed track representing a first musical timbre selected from the predetermined musical timbres of the first piece of music and a second decomposed track representing a second musical timbre selected from the predetermined musical timbres of the first piece of music;
• a transport control unit adapted to be operated for applying a transport control for controlling transport of the first decomposed track with respect to time;
• and
• a recombination unit for recombining audio data obtained from the first decomposed track with audio data obtained from the second decomposed track to obtain recombined audio data.
