I got very spoiled using Logic Pro X on a Mac Pro. Just click on the end of a region, hold option, drag, done. It sounds pretty good too, much cleaner than I would expect. But now that I’m using my old Macs more, I find that the time stretching algorithms available are way too dirty and are filled with artifacts. SVP for example.
What’s the best in your opinion?
Lots of variables here…
Are you comparing OS9 and OSX time scaling using identical sample and bit rates? How far you "pull" the the time counts too.
Scaling in "the old days' is less "grab and stretch" than in later apps. Also, SVP and the Acadia audio engine for example, was not designed so much with that kind of manipulation in mind as was PT and DAE, which were "born" more for use in the film industry.
* Note there is also interaction between the "new" audio created with different interpolated sample values and the ADA you happen to have. Resampling digitally encoded audio to be longer in time without changing pitch is a messy business at best. The amount of change, the original sample bit rate, the characteristics of the converter and the
nature of the audio itself (big difference between say, a sustained violin note and a sawtooth-based synth and a male vocal etc.) and your personal tastes. What I'm trying to say is that your
perceived result depends an a lot of things and getting an unsatisfactory result on project "A" does not guarantee the same result on project "B".
All else being (reasonably) equal, for maximum sonic "purity", I vote for Sonicworx.
