Looking for Information About Streaming Audio Formats

	Has anyone run across any information that describes how
the protocols used by common streaming audio services work?

	I think one might be able to figure out some of what happens
by placing a Linux system running snort in full capture mode on an
Ethernet switch port with a Windows box as it makes a connection to a
radio station's web site or something similar.

	Has anyone run across any discussion of the nuts and bolts of
how these streams are decoded?

	There are actually two issues that must be resolved; One is
how the data communications are set up with the remote server to start
the stream and, of course, how to turn that stream in to audio after
it is being received.  The snort capture would probably tell you
enough about the communications protocol to figure out how it works,
but the data decoding part of the puzzle is probably the hardest.

	Any ideas are appreciated.
