ABSTRACT:
A circuit for generating a multi-channel audio output from a single channel input. In the circuit, the single channel input may include gain control. The circuit divides the single channel input into at least two signals, each of which may have applied to it gain control, time delay, tone control and/or phase inversion. The gain controlled, time delayed, phase inverted and/or tone controlled signals are each input to an amplifier to create the multi-channel audio output.
