RE: Jitter and music software

"Everyone again... jitter is only causes when a audio signal is wrapped around a synchronous clock."

I'm not sure if this is your view or the article's view (I could not find the statement you quoted on the site, by the way), but there is no such thing as a clock or data stream that is totally jitter free..... So a lot of things, and most-likely a combination of things, can cause jitter. (A synchronous clock, if anything, is a lesser offender here.) And I'm sure some jitter spectral measurements would bear this out.

In my opinion, the effects of software (and storage formats) on jitter has been a grossly under-investigated subject in audio design world. But at least it's an issue being raised on a computer audio site.

I have speculations on what might cause jitter in computer playback (varying playback latency, variations in CPU load, variations in seek times, etc.), but until we have studies on its behavior and effects, most of what has been stated is speculation. The only thing I will say is that I think it's an issue that's real and should be addressed.
