Method for processing and playing audio data using DJ equipment, comprising the steps of: a) receiving first mixed input data, said mixed input data being a sum signal obtained from mixing at least one first source track with at least one second source track, and receiving second mixed input data, said second mixed input data being a sum signal obtained from mixing at least one third source track with at least one fourth source track, b) decomposing the first mixed input data to obtain at least a first decomposed track resembling the at least one first source track, and a second decomposed track resembling the at least one second source track, and decomposing the second mixed input data to obtain a third decomposed track resembling the at least one third source track, and a fourth decomposed track resembling the at least one fourth source track, wherein decomposing the mixed input data includes processing the mixed input data by an artificial intelligence system, c) generating output data, wherein generating output data comprises recombining the first decomposed track at a first volume level, the second decomposed track at a second volume level, the third decomposed track at a third volume level and the fourth decomposed track at a fourth volume level, to generate recombined output data, d) playing the recombined output data through an audio output; wherein the method allows a user to manipulate the volume levels of the first as well as the second decomposed track individually, and wherein the method further comprises a step of reading a control input from a user, said control input representing a desired setting of the first volume level of the first decomposed track, the second volume level of the second decomposed track, the third volume level of the third decomposed track, and the fourth volume level of the fourth decomposed track, such that the user has an opportunity to recombine the decomposed tracks individually at the desired volume levels. a) receiving first mixed input data, said mixed input data being a sum signal obtained from mixing at least one first source track with at least one second source track, and receiving second mixed input data, said second mixed input data being a sum signal obtained from mixing at least one third source track with at least one fourth source track, b) decomposing the first mixed input data to obtain at least a first decomposed track resembling the at least one first source track, and a second decomposed track resembling the at least one second source track, and decomposing the second mixed input data to obtain a third decomposed track resembling the at least one third source track, and a fourth decomposed track resembling the at least one fourth source track, wherein decomposing the mixed input data includes processing the mixed input data by an artificial intelligence system, decomposing the second mixed input data to obtain a third decomposed track resembling the at least one third source track, and a fourth decomposed track resembling the at least one fourth source track, wherein decomposing the mixed input data includes processing the mixed input data by an artificial intelligence system, c) generating output data, wherein generating output data comprises recombining the first decomposed track at a first volume level, the second decomposed track at a second volume level, the third decomposed track at a third volume level and the fourth decomposed track at a fourth volume level, to generate recombined output data, d) playing the recombined output data through an audio output; wherein the method allows a user to manipulate the volume levels of the first as well as the second decomposed track individually, and wherein the method further comprises a step of reading a control input from a user, said control input representing a desired setting of the first volume level of the first decomposed track, the second volume level of the second decomposed track, the third volume level of the third decomposed track, and the fourth volume level of the fourth decomposed track, such that the user has an opportunity to recombine the decomposed tracks individually at the desired volume levels. wherein the method allows a user to manipulate the volume levels of the first as well as the second decomposed track individually, and wherein the method further comprises a step of reading a control input from a user, said control input representing a desired setting of the first volume level of the first decomposed track, the second volume level of the second decomposed track, the third volume level of the third decomposed track, and the fourth volume level of the fourth decomposed track, such that the user has an opportunity to recombine the decomposed tracks individually at the desired volume levels.
