One thing I forgot to mention which I'm sure was pointed out already is
that you don't need to be root to record. If you're getting permission
errors opening your sound device and it isn't in use by another process,
make sure your user is added to the audio group. I found that adding
the user I store most of my files under to the audio group solved a lot
of problems. This is definitely true with sox and MPlayer as I use both
as a normal user regularly.

I have some questions for you. First, is the audio that you want to
record primarily online streams or do you want to record with an
external source? If you want to use a microphone or similar, I don't
know what to suggest. However, if it's mostly streams you want, just
use MPlayer and have it output to a PCM wave file. You can then use
sox, lame or oggtools to encode to mp3 or ogg. Also, if it's an mp3
stream such as shoutcast, icecast or similar, wget should work
nicely. If it's Windows Media, try mmsclient. In the case of
MPlayer, this is what I use:
mplayer -quiet -vo null -ao pcm file.rm
It also supports .asf and obviously online streams and playlists. If
it's an online mp3 stream, do something like this:
wget -b -i file.m3u -O file.mp3
You can also pass a URL instead of a .m3u playlist. I have recorded
streams for years this way. Be warned that the wget method does not
write proper mp3 headers. I've never had a problem with the files
playing, but technically they aren't valid.

By chance, are their better programs in non-graphical to record audio
from my sound-card? Hopefully without always switching to root.
I seem to have an mp3blaster, but in alsamixer, it is missing any
options for increasing treble, so I handle that in mplayer.
