How the FLAC do I tell MP3s from lossless audio?

Canadian double-blind test

(Mailed to me:):

In your article on lossy vs. lossless audio you said, "Everything between sample points is lost." Please read up on the Nyquist–Shannon sampling theorem at Wikipedia, which states in part, "no actual 'information' is lost during the sampling process," given certain sampling conditions. This is scientific truth.

Please read the very long and detailed web page at for more information on lossy audio reproduction.

If you've heard of the placebo effect you will understand why people believe lossless audio reproduction MUST be better than lossy reproduction, and hear it as such. But the Canadian Research Council have conducted extensive double-blind (very important) listening tests. At sampling rates 256 Kbps and above, with a good encoding, only golden-ears individuals (that's not you or me or most people) can hear ANY difference at all.
