Method, device and software for applying an audio effect

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 audio track representing a first musical timbre selected from the predetermined musical timbres and a second audio track representing a second musical timbre selected from the predetermined musical timbres;
• an effect unit for applying a predetermined first audio effect to the first audio track, but not to the second audio track;
• a recombination unit for obtaining recombined audio data by recombining the first audio track with the second audio track;
• an effect control unit for allowing a user to (A) control operation of the effect unit, in particular an application of at least the first audio effect to the first audio track, or (B) actively switch on/off or change at least the first audio effect,
• wherein the effect unit controls a plurality of audio effects, and wherein the effect control unit comprises an effect control element, wherein the effect control element allows a user to select at least one audio effect from the plurality of audio effects as the first audio effect to be applied to the first audio track.

A non-transitory computer-readable storage medium comprising computer readable program instructions stored therein that when executed by a computer cause the computer to perform operations comprising:

• providing input audio data representing a first piece of music, the input audio data comprising a mixture of predetermined musical timbres;
• decomposing the input audio data to generate at least a first audio track representing a first musical timbre selected from the predetermined musical timbres for an entire time of the input audio data, and a second audio track representing a second musical timbre selected from the predetermined musical timbres for the entire time of the input audio data;
• applying, to the first audio track, a predetermined first audio effect;
• applying, to the second audio track, (A) no audio effect or (B) a predetermined second audio effect, wherein the predetermined second audio effect is different from the predetermined first audio effect;
• and
• obtaining recombined audio data by at least recombining the first audio track having the applied predetermined first audio effect with the second audio track having (A) no audio effect applied or (B) the applied predetermined second audio effect.
