GADGOOKS! that's no tutorial, that's *torture*. After i finally
got caught up on miised sleep, a few hours ago I read-thru and
listened-to (kttsd) the man lame. Then surfed around; then came
back to the man page and read the several examples. So: the idea
is that lame ["just"] converts WAV files to mp3. There is a
gnome utility, sound-juicer than turns my CD's from wave to
ogg-vorbis. I'm happy with ogg but would prefer flac ... but ogg
is fine. mp4 is a dontknow. What I've got is good enough for
now.

Sounds v promising, thanks.
Given the availability of compression these days, it makes me
wonder why telephone conversations still sound so 'tinny'. But
then, that's another matter.
