Thanks for the links.
Actually I know a fair amount about audio from a programming project a
few years ago. One way to think about it is that all digital audio is
pcm and everything else is compression.
That is, the digital sound goes to the device and, if it's not already
pcm, is converted to pcm and then converted to analog for the speakers.
There are a ton of different compression formats. What I am interested
in right now is the proper configuration of different applications in
BLFS to get the appropriate input (CD/DVD, network, file, microphone) to
the proper sound device for delivery to speakers (headsets are speakers

Yes, I am reasonably familiar with the internals of mp3 and ADPCM.
These types in compression are not my focus right now as that's
generally handled pretty well by available libraries.

That's a nice list. Thanks for the feedback.
