i think CLAM only provides mp3 only as matter of space... anyway a
couple of short examples in wav or links wouldn't hurt

maybe look here? http://freesound.iua.upf.edu/

I can't see your point clearly, you also could tune an algorithm to a
fixed example... I think main problem it's about lossy property of
mp3... (basically you're losing spectra and resolution... and if you
chain encodings would be worst and worst)
