I hadn't done more than five iterations on the same material, but I followed your steps on Win 7 x64 and did 30 iterations on that tone without getting a failure to progress. I assume it's OK to be slower each time, as it is processing longer audio each time. It appears that after the eighth iteration, the effect doesn't do more than add near-silence at the end (and at the start). It does the same with a piano sample of 10 seconds too, but needs 12 iterations before this happens. Just a limitation of the algorithm in face of "unreasonable" requests? The "silencing" doesn't seem to happen with 30 iterations of -5%, -5% tempo change without the pitch change. I'm still waiting for that one hour audio to time scale on Win 7 32-bit (a -5% tempo reduction). It's working, but been three hours now and another 30 minutes still to go. Gale |
