	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.
