Abstract
A system for mixing five channel sound which surrounds an audio plane. The position of a sound source is displayed on a VDU (16) relative to the position of a notional listener (31). The sound source is moved within the audio plane by operation of a stylus (23) upon a touch tablet (24). Thus, an operator is only required to specify positions of a sound source over time, whereafter a processing unit (17) calculates actual gain values for the five channels at sample rate. Gain values are calculated for the sound track for each of the loudspeaker channels and for each of these specified points. Gain values are then produced at sample rate by interpolating calculated gain values for each channel at sample rate.
