AI-based DJ system and method for decomposing, mixing and playing of audio data

A method for processing and playing audio data, comprising:

• receiving first mixed input data, the first mixed input data being a first sum signal obtained from mixing a first source track with a second source track;
• receiving second mixed input data, the second mixed input data being a second sum signal obtained from mixing a third source track with a fourth source track;
• decomposing the first mixed input data to obtain a first decomposed track resembling the first source track and a second decomposed track resembling second source track;
• decomposing the second mixed input data to obtain a third decomposed track resembling the third source track and a fourth decomposed track resembling the fourth source track;
• reading a control input from a user, the control input representing a desired setting of a first volume level of the first decomposed track, and a second volume level of the second decomposed track, a third volume level of the third decomposed track, and a fourth volume level of the fourth decomposed track;
• reading a swap control input from the user, the swap control input representing a desired increase in the first volume level of the first decomposed track and a corresponding decrease in the third volume level of the third decomposed track;
• recombining the first decomposed track at the increased first volume level with the second decomposed track at the second volume level, the third decomposed track at the decreased third volume level, and the fourth decomposed track at the fourth volume level to generate recombined output data;
• and
• playing the recombined output data through an audio output.

A device for processing and playing audio data, comprising:

• an audio input unit for receiving first mixed input data, the first mixed input data being a sum signal obtained from mixing a first source track with a second source track and for further receiving second mixed input data, the second mixed input data being a second sum signal obtained from mixing a third source track with a fourth source track;
• a decomposing unit connected to the audio input unit for decomposing the first mixed input data to obtain at least a first decomposed track resembling the first source track and a second decomposed track resembling the second source track, and for further decomposing the second mixed input data to obtain a third decomposed track resembling the third source track and a fourth decomposed track resembling the fourth source track;
• a swap control element for reading a swap control input from a user, the swap control input representing a desired increase in a first volume level of the first decomposed track and a corresponding decrease in a third volume level of the third decomposed track;
• a recombination unit for recombining the first decomposed track at the increased first volume level with the second decomposed track at a second volume level, the third decomposed track at the decreased third volume level, and the fourth decomposed track at a fourth volume level to generate recombined output data;
• a recompose controlling section comprising a first on-off switch operable by the user to individually mute or unmute the first decomposed track, and a second on-off switch operable by the user to individually mute or unmute the second decomposed track;
• a playing unit for playing the recombined output data;
• and
• input means for receiving an input of the user for performing scratching effects during live performance or skipping to different time positions in a song during playback of the recombined output data.
