FIG. 3 further shows in an alternative embodiment that the controller can define a pattern 17 on each modified sub-signal flow layer. FIG. 2 shows particularly an embodiment wherein a volume pattern 17a1, 17a2, . . . is defined, which is repetitively replicated. In the alternative embodiment a sinusoidal volume pattern is illustrated. Volume pattern 17a1 is provided with a different starting point than volume pattern 17a2, 17a3, etc. It will be apparent that any pattern can be applied to the modified sub-signal flow layers. A pattern can for instance also be a timbre pattern. It is alternatively also possible for a pattern not to be repetitively replicated.
The signal flows can for instance have a Dolby Surround, Dolby Surround-Ex, Dolby Atmos, DTS, DTS-ES, Auro 3D, SDDS format. It is also possible to manipulate any other form of surround audio.
In the illustrated embodiment of FIG. 1 a 6-channel surround sound audio file is illustrated. It will be apparent to the skilled person, as illustrated in FIG. 3, that 7.1, 10.2, 11.1, 22.2 surround sound audio files, or variants thereof, can also be manipulated.
It will be apparent to the skilled person that the sub-signal flows can have any audio coding format. The sub-signal flows can for instance be converted into MP3, WAV, AAC, but are not limited thereto.
