Can it be done without flutter?

Yes, but it's not a point and click proposition and cannot be taken too far..any time compression expansion will cause artifacts..but picthing is something you might want to consider doing in sound forge for best quality

I usually open a copy of my file in SF and manipulate it and save it back to Vegas. I just am not well enough aquaited with the pitch bend software to get a file without flutter. Any suggestions would be appreciated.

Give me some specifics of how far you're looking to stretch it (give me rough timing differences) and how much quality you're reasonably hoping to preserve

Assuming you're wanting to raise the pitch of an audio clip, select it in the timeline and press either the + or - keys. + shifts it up, and - shifts it down.

Are you asking how to do this at all in Vegas or are you not satisfied w/ the results you're getting?

To stretch an audio clip where pitch is adjusted (and not just time) you can change the global setting ( Options/Preferences/Editing/ Uncheck "Preserve pitch when stretching audio events").

To stretch a clip put hover the mouse over the left or right edge of the audio clip, then press/hold the Ctrl key (should see a squiggly line appear on the mouse cursor), drag the clip and you can then stretch it (or shrink it). Once stretched if you right click it, pick properties, and look at the bottom of the "Audio Event" tab you'll see specifics related to the stretching. If you tick (or untick) "lock to stretch" next to pitch change that'll switch Vegas from stretching with or without pitch change or not. The method should be elastique'. In the past there may have been other options (I sorta remember a "Pro" vs. Basic or something) but elastique' I believe is the best at least in 14 which I'm using.

If you knew all but you're just not happy w/ the quality of the pitch change sorry but maybe this explanation will help someone else.
