Realtime sound generation in LC

a few years ago I got into trying to export audio files imbedded inside
Livecode to wave and aif and I got it to work, but just dealing with the
pointers and grokking how Livecode stored audio was a challenge.  I didn't
try any processing.

The late Mark Smith was way ahead of me and even had a waveform display and
a traveling cursor line on playback.... it was brilliant. I think his
stacks are still online somewhere. We were going to collaborate before he
died. this way back about 2007 when I was still working for Mike Markkula
and Jerry Jensen.  I have my stacks around somewhere but it stopped working
at some version I can't remember. My notes aren't human readable.

I started that because I had uncompressed audio files trapped inside rev
stacks but there was no way to export audio built in. I always thought that
was odd.
