Cryptic claims made elsewhere (so-called, audible differences between FLAC & WAVE)

I'd just like to see some commentary on the claim in this thread about someone who is claiming they can hear the difference between WAV and FLAC: http://iaudiophile.net/forums/showthread.php?p=84975 (skip to page 3).

This individual seems to mistakenly think that FLAC utilizes some algorithm that interferes with the high frequencies (making them "better" to his ears). blink.gif I obviously think he's imagining these differences or being deceived by a decoder as referenced in the thread (he ignores that suggestion, though).

Perhaps the FLAC developer can set him straight because he seems to think he's rather knowledgeable on the topic. rolleyes.gif

EDIT: Doh, I exceeded the limit of chars for a topic (no warning ;( )

You know, not to defend the retard there, if you actually listen to FLAC against WAV on a PC, you might hear different... if you use AMD's Cool&Quiet technology. As WAVs are just dumped into Windows Mixer, it should (theoretically) use less CPU power and thus makes the fan go slower. FLACs need to be decoded and thus use more CPU power and makes the fan go faster, thus noisier.

But I don't have Cool&Quiet, so this is a hypothesis. Anyways, FLACs and WAVs will produce exact bit-by-bit match, and if you can totally isolate the effect of varying fan speed, there's no difference.

...and what a wonderfully unrealistic one wink.gif. CPU usage will probably be 1% when playing FLAC in realtime, and the CPU will certainly not "power up" to a higher clock rate for such an easy task, thus the fan speed will stay the same.

Exactly. wink.gif I use Cool 'n' Quiet on an AMD64 3000+ and the multiplier values I'm seeing are 5x, 9x and 10x. The only audio-related job that can push the multiplier above 5x and make the fan rev faster and be audible is, of course, encoding.
