audio tempo envelope editing???
 

Hi
does anyone know of software that uses tempo envelopes for audio, i know it is common for video, like vegas, but for audio, or audio and video toogether? I tested vst plugin waves soundshifter G, but is very unstable and almost impossible to sync it with video envelope, of course i tried audition, vegas, AAE, nothing can do it, or maybe i'm just ignorant

thanks for any knowlege
