Claim:
A process for enhancing ambience in audio source signals comprising the steps of: generating a first audio signal; generating a second audio signal; delaying and attenuating said second audio signal to form a third audio signal; summing said third audio signal with said first audio signal to form a fourth audio signal; delaying and attenuating said first audio signal to form a fifth audio signal; subtracting said fifth audio signal from said fourth audio signal to form a sixth audio signal; delaying and attenuating said second audio signal to form a seventh audio signal; subtracting said seventh audio signal from said sixth audio signal to form an eighth audio signal; delaying and attenuating said first audio signal to form a ninth audio signal; and summing said eighth audio signal with said ninth audio signal to form an output signal for one channel of a multiple channel audio system for driving a speaker; whereby the ambience of one channel of an audio system is enhanced.
