Wav from sound card line in

[McCy Ron]

I'm using FreeBSD 4.10 and would like to make WAV format recordings from 
my sound card's "line in" channel
with some sort of "command line" utility. I've been successful in 
finding other sorts of ports and packages to rip CDs
and play Wavs and MP3s but have yet to find anything in the software 
descriptions that address this need.

Can anyone recommend something?

Thanks
