Time Stretching sound quality

Previously, my favorite software was Mixvibes Cross DJ 3.4.3, with Serato a close second (only due to a lack of a dedicated track preview feature). IMHO, the new Cross DJ 4 is not good, so I searched for a something that could be configured "most like" the old 3.4.3, but obviously with improvements.

Native Instruments have gotten a lot of bad press recently - none the less, I've been doing some serious playing around with Traktor Pro 3. I can now say with some confidence that TP3 version 3.2.0, with the new "Elastique 3.3.0 Time Stretching" algorithm really sounds good, even at Tempo changes greater than 4% - and it's not a cpu hog.

Most of you know that I frequently DJ for a large group of elderly Latinos here in south Florida. They are dancing fools, but since they are older, I often slow the music down (mainly Salsa Dura and Merengue), usually without telling them. I am also highly critical of sound quality.

Using my Sony MDR-7506 headphones, I can say with some confidence that Serato DJ Pro (with the optional Pitch'n Time plugin), and this new version 3.2.0 of Traktor, are the finest I have personally heard, and are capable of Tempo changes close to 10% without hearing an artificial vibrato being added to voices.

Have you ever used Audition 3.0?
No. I have used Audacity to create my own custom edits with altered Tempos greater than 4%, but (probably should have made it a little clearer) I was referring to doing it real time, while actually DJ'ing.

I agree with Cap.
I use Adobe Audition at work (creating radio commercials)
and it has a VERY good time-stretching feature.

But I assume the limits are the same for any time-altering program.
The only quality problem I have seen (heard)
is trying to trim 2 or 3 seconds off of a 30-second commercial.
Time stretching a 3-minute or longer song should not have an issue.
