Claim:
1. A multi-channel audio system that can provide a variable sub-sample delay between two audio channels, comprising: a first digital to analog converter (DAC) to convert a first digital audio channel into analog form using a first clock signal, wherein the first digital audio channel comprises a sequence of symbols driven at a sample rate, and wherein each symbol is to be latched in the first DAC by the first clock signal at the sample rate; a second DAC to convert a second digital audio channel into analog form using a second clock signal, wherein the second digital audio channel comprises a sequence of symbols driven at the sample rate and wherein each symbol is to be latched in the second DAC by the second clock signal at the sample rate; and a variable timing clock generator to generate the first and second clock signals having different phase, wherein the clock generator is to vary the phase difference between the first and second clock signals in accordance with a sub-sample delay setting input.
