You *do* realize that mp3 is a "lossy" compression. The only way to
convert them is to "uncompress" them back into 44.1Khz stereo samples
(aka a "wav" file) and then to "recompress" them as oggs. The problem is
that most of the "uncompressed" actual data is *synthesized* (i.e. made
up out of random data - although it's not quite random, technically) and
then you are recompressing *that* as if it really were "real" data when
you convert it back down to oggs. You can do so, but you might get
aliasing and other artifacts of the process that result in audible
defects - harmonics, tonality, etc. that are undesirable, and perhaps
You really want to re-rip them from the original if you can.

Don't know. It's not quite Perl as I understand it. Let's just say that
describing those features of apt as "under-documented" is being
generous. Perhaps you'd care to write some? There's a Debian wiki at
