In the context of the description dimension is further defined in accordance with the number of layers of a signal flow. Each signal flow has a determined number of layers. For audio it is known to transmit different layers to different locations in a space. It will be apparent to the skilled person that mono sound has one dimension, also written as 1D, that stereo, which has two layers, has two dimensions 2D and that 5.1 surround audio has 6 dimensions 6D.

In the context of the description a controller is further defined as a device which transmits a signal on the basis of a physical input. It will be apparent to the skilled person that a controller can be any one of a computer mouse, touchpad, keyboard, Musical Instrument Digital Interface MIDI device, etc. It will be apparent to the skilled person here that the controller is not limited to the above described examples.

FIG. 1 shows a general flow of the method for live manipulation of signal flows 1a, 1b, . . . via a controller 15. Signal flows 1a, 1b, . . . are typically fed into a processing unit 9. The signal flows 1a, 1b, . . . in FIG. 1 are surround audio flows, more specifically a 5.1 surround form. Signal flows 1a, 1b, . . . each have 6 signal flow layers 2a, 2b, In the case of 5.1 surround audio these channels are typically used for left, right, center, rear left, rear right and LFE signals. It will be apparent to the skilled person that the method also provides for live manipulation of more than two signal flows 1a, 1b, 1c, 1d, etc.
