Recent discussion has included books on massageing waveforms.  I am 
interested in the ability to change time without changing  pitch.  This 
then allow one to set a locally made tape of a poetic reading of a 
commercial such as "Eat at Joe's diner, on the corner of nth and etc."
to the prerecorded classical or other musical background.
  In the discussion of a book by F. Richard Moore called ELEMENTS OF
COMPUTER MUSIC I think I heard mention of pitch change without time change.
If anyone knows if time change without pitch change is also contimplated I 
would like to know. Also other source. 
  It seems someone also mentioned that it might take sixty seconds of large
scale number crunching to get one second of sound.  Parallel processing may
improve this and some of the supercomputer centers might need extra work.
 Imagin patching a duet of Michael Gorbechev and Ronald Regan singing 
what a friend we have in jesus or the "international."
