I write not because I have a great proffesional knowledge about the 
subject but rather because I have a great belief that widespread knowledge
of the topic will help humanity. Over the last four or five years 
discussions on the Internet in groups like comp.music, comp.ibm.pc.soundcard,
comp.dsp topics like "time change without pitch change, csound,
phase vocoder, pvoc, ELEMENTS OF COMPUTER MUSIC by F. Richard Moores have
appeared.

More recently discussions in comp.speech, the FAQ, and software for
recognition and synthesis seem to algorhythms in c code. I have a
pc clone 486, 50 mHertz, 1 gigabyte HD and Sound Blaster Audio cards.
I hope we will eventually see posting of the results of your most
interesting topic.

My envisioned need is most involved with audio tape collections of
classic literature in multiple languages, most notably The Bible, in
large part and the Psalms in small part. I want to play two selections
simulteneously and have them adjusted to keep the tracks in somewhat
close time sync. Eventually I think this process will apply to 
multilingual broadcast of international news from satellite to home.
