Time Stretch

Am I missing something in Vegas? When I apply the Time Stretch plug-in on any track, and the time is compressed or expanded, the waveform in the track does not adjust to reflect where the audio will actually end. So, I have to adjust the time for the file in Sound Forge and then open it back up in Vegas. I hear other applications don't have this problem. Can anyone help?

I usually use Ctrl-Drag at the end of the clip to resize it, then right-mouse-button click to go to properties to choose the time stretch method i want.

Thank you, I tried that, but the result was a very "chorused" effect. I've found that Vegas doesn't handle time stretching very well. The best result I've found came from using the Time Stretch plug-in, then rendering that track and re-inserting it into the mix as another file.

You didn't mention what version of Vegas you are using but V4 has much improved time streching routines.

There is no mechansim for a DX plugin to communicate this information to the host app so there would be no mechanism to adjust for this in the UI/timeline.

What other applications don't have this problem?

Regardless, these types of plugins are very bad to use in realtime, expecially if you are compressing the time. We strongly recommend against using these or any plugins that mess with the time/duration of audio other than destructively.

This is why we have event streching built into Vegas. If the quality of this is not sufficient for your needs, then the best solution is to render the track to New or to apply the time strech as a destructive FX on and event by event basis.
