MP3 evaluation software

To evaluate the effect of MP3 conversion on an audio file, I would like to find software will produce a WAV file that is the difference between the best match between two sample WAV files.

If File1.WAV is the original, and is converted to File2.MP3 and then reconverted to File3.WAV, the difference between File1.WAV and File3.WAV (= file4.WAV) should reveal the sound lost (or added) in compression, provided that one can match the sync and levels appropriately.

Nelson Pass On The Patents Of Pass

If high-end audio were to carve its own Mt. Rushmore, whose faces would appear there&#151;besides that of <I>Stereophile</I> founder <A HREF="http://www.stereophile.com/interviews/66">J. Gordon Holt</A>, of course? It's likely that no two audiophiles would ever come up with identical lists of subjects, but I wouldn't be surprised if they could agree on at least one name: <A HREF="http://www.stereophile.com/interviews/1191pass">Nelson Pass</A>.

Lost gems people should go seek out.

Last night I pulled out an album from 1977 and was thinking about how every now and again, there comes an album that insinutates itself into your rotation that never makes it to the 'reissue zone' and deserves higher regard than being left behind.

So, what are your lost gems that you would encourage people to seek out and acquire?

I'll limit myself to two:

1) Karla Bonoff's eponymous album from, as I mentioned, 1977. It's got Waddy on it, and Wendy Waldman, Linda Ronstadt, Kenny Edwards, Andrew Gold, JD Souther, and Glenn Frey.
