<p>A sound placement system (100) and process produces from a plurality of input audio signals (118-120, 124-126, 127) at least two different output audio signals (131) which, when reproduced through respective speakers, give to a listener the illusion of distinct sound sources distributed into a three-dimensional space surrounding that listener. A multiplexer controller (103) combines the input audio signals (118-120, 124-126, 127) into at least one combined signal (128), and a demultiplexer controller (601) divides this combined signal (128) into multiple channel audio signals (604, 605, 606). Finally, a sound imaging unit (104) processes the multiple channel audio signals (604, 605, 606) to produce the two different output audio signals (131). A digital storage unit (111) is provided to store either the combined signal (128) or the output audio signals (131), and to supply them back to the multiplexer controller (103) for further combining and processing thereof.</p> |
