just getting my audio settings adjusted./
Was wondering: about how much, percentage wise, should I expect to time stretch something before it "starts to sound stretched",. Generally speaking.
A broad topic, eh?

Very broad. :)

I'd say anywhere from 15% to 30% of the original is when you'll start to hear artifacts. Different material also produces different results. Be sure to experiment.

If you have ACID Pro, be sure to play around with the stretch markers under the track properties (via the Stretch tab); they can certainly help you out in a lot of cases. (You'll want to place markers on subdivisions of a beat you feel need to be stressed.)

You're welcome! :)

I forgot to mention to play around with the "stretching method" option under the same tab too. Some material works better with a certain setting than others. (e.g., the "pitch shift segments" setting can help with extreme tempo changes.)

You're likely to get a subjective answer with that question, but stretching digital audio too far will eventually produce artifacts, which is the nature of the digital beast. Sound Forge has tools that will lessen the impact of these artifacts, but your best bet is not to stray too far from the original tempo.

For me it’s Prosoniq Time Factory, it will give you results in a whole other stratosphere than Sound Forge.

Can be transparent even over large tempo variations.

Have used it on numerous major label releases with everyone involved being extremely happy with the results. Can’t recommend it highly enough!

Thank you. Does it support ASIO drivers too?

Sony doesn't offer any hope for their loyal users. I am hesitant on giving them anymore of my business.

Err...no...You asked what was the best program for time stretching.

Time Factory is a stand alone application that does extremely high quality time stretching and pitch shifting and nothing else.

...In what way aren’t Sony offering any hope for their loyal users?
