What exactly do you want to do?

I guess I don't need to mention audacity for recording? But there's
also Alsa's command line recorder arecord.

There's a lot of audio analysis/visualization software out there, here's a few:

sonic-visualiser - probably one of the most feature rich but not
always easy to install.
jaaa - Jack/Alsa Audio Analyser
japa - Jack/Alsa Perceptual Analyser
SND - loosely modelled after Emacs apparently - extensible - steep
learning curve.


But like I say, streaming I'm not familiar with. Doesn't VLC do streaming?
