First, I'm on Sonar Platinum, Dorcester update.
The other day at rehearsal, I played an old track in Traktor, slowed down. It sounded awesome.
 
Now in Sonar, I'm trying to take a sample of this old track I did at 95 bpm and simply slow it down to 75 bpm. Simple enough, one would think. But when I stretch it, it wants to keep the pitch and stretch it nicely. I want it to slow down, pitch down (about 20%) and sound ugly and bad. I can't get it to do that. Every alg I look at preserves pitch and transients. 
 
I used to be able to grab the edge, stretch it to fit, and bounce it to clip. This would "preserve neither"... but now I can't get it to do that. Is this gone from the new Sonar(s)???  

This tells how to do time-stretching without preserving pitch. Although it's about fine-tuning, you can use the same principle for larger tuning stretches. For more detail on "varispeed" techniques, check out this column in Sound on Sound magazine.
 
If you're looking for the old, super-funky pitch stretch algorithm I don't think it's been in SONAR for a while...maybe it's one of those 32-bit orphans, or maybe you could re-install from an older distribution disc.

Side note: In my opinion, Traktor has the best time / pitch adjustment I've yet encountered; I'd say even better than Ableton. noting that Sonar doesn't do it as well as Traktor is fair enough, but unremarkable. Nothing does it as well as Traktor. They've been nailing that for well over a decade IMO.

Thanks for the replies, Gents...
Nothing was working right. The old Direct-X Cakewalk pitch/time was close, but the transposition math (-8.666667%)got too hard.
Finally the solution was to export it from Traktor, which equals the sample as it sounds in Traktor. Of course this took another hour to google.
BUT I got my sample.... of myself.

If you are willing to go outside of Sonar, Waveagent, a free download, is a Swiss Army knife for wave file manipulation which can do the job you describe by modifying the wave file itself, and rather quickly.

Intense effort has been put into the time change/pitch stable and pitch change/time stable functions over the last couple of decades, since these are almost always what audio editors want. They require pretty complex algorithms to avoid the distortion in pitch you are seeking and the altered formants in vocals especially. The peak demand for chipmunk voices has passed.

Today's good news!

That sounds like a nice little program, I'll have to check it out myself for speed-factor.
I love good free programs that are also BS-free.
Thanks
