Abstract
A method of managing multiple channels of audio data in an audio system having multiple speakers. A first channel signal is selectively passed through a software high-pass filter to selectively drive a first one of the speakers. A plurality of channel signals are selectively summed in software to generate a composite signal and the composite signal passed through a software low-pass filter to selectively drive a second one of the speakers.
