I've NEVER had that experience with Varispeed it always sounds glitchy to me. What I haven't had good results from is Varispeed, although David says that guys out there are doing great work with it, speeding up whole mixes and it still sounds good. I've changed whole performances on a phrase by phrase basis, again with excellent results using flex and the tempo track. Sometimes we've even been able to keep the vocal in it's speeded up state.

No problem, I flex all the audio tracks and then speed the song up by choosing a new tempo. Client comes back after initial tracking and decides that the song is too slow. Yes, it's possible to tweak the settings in Radius but it's a bit hit and miss sometimes and Radius can take a long time to process a single track if it's say a minute or more long.įor the kind of thing you're trying to do, I've used Flex lots of times with great success. Now I use both Flex and Radius and frankly, sometime Flex does a better job. I got it years ago (long before flex was available) and instantly all my time stretch and pitch change work in the sample ed went up a big notch.
