发明名称 Polyphonic sound system
摘要 The present invention concerns a polyphonic reproduction of sounds and particularly individual notes produced by musical instruments or the sounds produced by a group of instruments. In the invention the sounds are separated across a notional aural spectrum by using audio signals which vary differentially in amplitude for the varying sound sources. The variation may be caused either electrically or by varying the positions of the transducers picking up the sound sources.
