steph YaBB Newbies Offline Posts: 20 spain	ess: changing pitch, non-destructive Nov 7th, 2005, 1:09pm   I was wondering if there's a way with the Ess library, to control the pitch/speed playback without modifying the sample; like with setRate() in the Sonia library.

It might be possible to add it in to the playback engine so it is done on-the-fly, but I don't have a lot of confidence that noise wouldn't be introduced. Timing in JavaSound is a nightmare.
