Jitter, Bits, & Sound Quality
Jitter is not what digital sound quality induces in the listener; rather it is the instability in the clock signal that controls exactly <I>when</I> the analog waveform is sampled in the original A/D conversion, or when the digital word input into a DAC results in an analog voltage being produced at the chip's output. "So what?" is the response of digital advocates, "As long as a digital one is recognized as a one and a digital zero as a zero, then how can there be any difference in sound?" goes their argument, normally culminating in a fervently expressed "Bits is bits!"
