The corresponding sub-signal flows are merged as according to the desired ratio in order to obtain a modified series of sub-signal flows. This is possible because the processing unit is working with Y sub-signal flow layers which can be processed by the hardware and software. In this way it is possible to influence the series of sub-signal flows. Application of the method according to the invention enables live manipulation in combination with a multi-dimensional aspect so as to thus be able to provide additional entertainment value to the audience during the live performance.

The signal flows are preferably audio flows and the signal flow layers are preferably audio channels which are provided to be transmitted to different loudspeakers in a space in order to obtain surround audio. The invention serves the particular purpose of playing so-called true surround. This is advantageous because it improves the perception of sound spatialization by making use of sound localization: a listener's ability to identify the location or origin of a detected sound in direction and/or distance. The method thus allows different audio files to be played from different loudspeakers.
