Hi Howard... The gist of the article is "sort of" OK, but the whole point of the psychoacoustic algorithms in lossy codecs is to try and throw away stuff we either can't hear or don't care about (at least that's the theory). So, using non-musical signals is by definition going to throw up all sorts of "issues" because the algorithms aren't designed for those signals... As for the footnote... The (biased) way I read it was "I appear to be somewhat grudgingly conceding that lossless codecs really are lossless, but I'm going to toss in this little nugget about vulnerability to 'transmission errors' because that will leave a little fear and doubt hanging in the air..." Clearly the author doesn't understand that flac actually does have CRC checksums... and that WAV doesn't have any extra magic "redundancy" built into it that makes it more robust! I think he is getting confused with the reed solomon coding for bursty error handling on CD's... I wonder why? -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
