Okay, I tested it again and I was sure not to get that low, but you're
right. Maybe I used -b 112 before, oggenc -h says this is the lowest
bitrate. Now I used -b 1 which encodes with the lowest possible bitrate
and I've got a 32.5kbps file. And it doesn't sound worse than mp3 (lame
--abr 32), although oggenc is not optimized for low bitrates. It's more
transparent than mp3, but the snare sounds a bit artificial (and
distorted?). Vorbis sounds better at low bitrates than I thought (not
as good as realaudio, but maybe one day. Generally it's hard to say
what codec is better at low bitrates. Some people say the best is WMA,
but I always hear the steadily flowing cymbals. Sometimes it's a matter
of taste).

Thank you Michael, now I could listen to my test stream at home, if I
get my script to pipe a wav header to oggenc (hope I doesn't need sox,
I hate it) :).
