AM quality, speaking in mp3 terms is about 40kbps, which is do able with
the new v.92s.  So, it would be good if I could stream that data, instead
of using a speaker phone, which at best is like 18kbps, or less. 

And, I know I'm going to sound like a heretic, but....

WMA, at about 48kbps is "FM Quality", which also happens to be the
upstream max for v.92s. So, if I could do that, then I could get a 
not-so-bad quailty stream across the direct connection.  Then, I will rule
to world.

Some one on another list suggested doing something like this:

sox -r8000 -b -U -t raw /dev/audio -s -w -t wav - | lame -b 24 - - 2> stderr  

(except, of course, redirecting stdout to /dev/modem)

Which is fine, if I want to use mp3. 


alternatively, I was thinking about using some asf/wma streaming software
over PPP connection.
