Hi Ted,"In any case if you can hear a problem with differing CPU loads then there is a problem with your setup and the specifics of the amount of load don't matter that much. Unfortunately experience tells us that CPU load is often audible."
Yes, and when it happens it manifests itself as clearly audible dropouts and "stuttering". However, it should be mentioned that this can happen whether you're playing back compressed audio, uncompressed audio, or video for that matter. Therefore it appears to me that we're talking about two separate topics.
a) The audibility of lossless audio file compression.
b) The merits of using a computer as a digital audio transport.
Ultimately I do agree with you regarding the issue of CPU load on audio playback performance, but I think that this speaks more towards topic "b" than topic "a". For this reason, I do not see any fallacy in Greg's post. It's obvious that a computer can be a perfectly capable audio transport as long as you don't overburden it with concurrent tasks. Once this simple rule is heeded, issue "b" shouldn't be a worry. However, the validity of issue "b" does not presuppose the existence of issue "a".
"There are reports here of people that indeed did A/B tests with lossless compressed vs. uncompressed with all other variables the same. As always the people who don't believe there is a difference don't accept that the experiments are controlled enough and the ones that do believe there is a difference don't care about anyone else's experiments"
Your last point hits home. We could continue debating the point of whether lossless compression has audible artifacts, but I'm really not inclined to do that. In the end, I've said my part and I respect the rights of others to state their opposing opinions. It's only when matters are presented as fact that I think we should ask for a higher burden of proof to be presented.
