I also use Cool Edit to do this, but it does mean multiple copies of
essentially the same information, Qian Chen's suggestion

would not only save on disk space, but would allow for experimentation
without ever leaving Csound, for an example: If i have a sound file of
10 seconds long, want it to play 1 second of it, but only want the 1
second "that sounds best to me", then i would prefer to be able to do it
within csound, also would it be possible to incorporate some kind of
looping facility into this new parameter (which would allow [me, at
least]to experiment with extracting steady state tones from sound files
of varying sounds. Finally, could this be controlled in realtime?.

	the duration of the note (p3) is the duration of the soundin.

	this is best done with a table-lookup instrument where the index
is created by an oscil/phasor with amplitude=loop length then added to the
skip time... 

	of course if you are using a multi-channel soundfile you are out
of luck - also problems with memory for large files (most so on a Mac).

	i always planned on writing a version of diskin that took
parameters like table, instead of soundin.  maybe i should look into that
now...


	the other option, of course, is to use some sort of score
generating program to create a new note for each loop.  this actually is
the most flexible (and in some ways the easiest) method, and the one i at
least prefer...

	that's a bug in diskin - will get on that - thanks.
