Sorry, I dont know the answer to this off the top of my head... Just saying hi and whatnot. I did not know that you posted in this forum ;-)
As for time-stretching... I wonder if Max can exploit the time-stretching features found in Quicktime 7. Open a movie or audio file and then press apple+k (on a Mac, not sure on Windows) and you will get options for pitch shifting audio as well as time-stretching audio/video.
Seeing as Max/Jitter and Quicktime are good buddies (^_^) maybe this functionality is exposed in Max/Jitter - if it's not perhaps we can ask the developers to add it in a future version.
Next time we meet we should have a Max hacking session I really want to come to Berlin in January). It's where I spend most of my time ;-)
