I have an interest in the above topic and would like some possible
bibliographical references from Journal Periodicals or other current
cutting edge sources.  Specifically, I would like to find out what
obstacles are involved with taking nine tracks of digital audio 
information multiplexing it into one stream of data and then compressing
that stream for storage so that later it could be uncompressed and
converted back into nine tracks without any audio degradation of
sound.  What algorythm would be best suited for the compression and
what would be the ultimate ratio of compression?  Also, would there
need to be other considerations in transferring the compressed data file
over ISDN?

Thanks.
