Hmmm...I can't change audio length and pitch at the same time?

I've never had reason to change both at the same time until now. If I go into properties and select "Change length and pitch," both the length and pitch change boxes are enabled. However, if I change one then the other changes, and vice-versa. I don't see any way to define a new time AND a new pitch.

I will instead change just the length and render it, and then change the pitch on that rendered segment. But did I overlook something when trying to do both at the same time?

Right click on the audio track, select the last option, (change length and pitch) then change the time for example from 7 minutes to 6 minutes, then add a value for semitones and/or cents. You got to manually enter both.

Darn... I forget, is it 12 or 24 semitones to an octative? Now, I'm not even sure that's right. LOL! Someone will know.

I think it's 12 notes to an octave. Anyway, changing both time and pitch at the same time is what I've tried, but when I change the second value, the first value adjusts to reflect the second value. In other words, say I change the duration from 7 minutes to 6, as in your example. If I then adjust the pitch 50 cents, the duration jumps to 6:50 (or whatever; you get the idea). In fact, you can watch the new duration change as you move the pitch slider.

Oops, I didn't notice. So, when you change the pitch it shifts the duration back up?

What if you use CTRL-Drag to change the length?

I did this a while back, I think in two separate operations - 1) Change length and pitch (to set new length with least artifacts), and 2) Change pitch, preserve length. Doing it this way kept the best quality, as I remember.

Try some different combinations and let us know how it works for you.

There's an option in Options / Preferences / Editing:
"Preserve pitch when stretching audio events".

If this is checked, you could try unchecking.

I've CTRL-Dragged the audio to the proper length, and then selected the tracks properties where I could choose to affect the pitch or not.

My experience shows that the quality of my audio (which was music) was better if I didn't try to maintain the pitch. I was only changing the legnth by .001% though (to fix a sync problem) so the pitch change was undetectable.

I wound up doing two separate operations, first changing pitch, and then length. I have not tried the opposite procedure to see how the artifacts compare.

The selection is of a high school choir touring Austria last summer. They are remarkably good as a choir, but this one song has them gradually getting flatter as the song progresses (it's a song sung at a very quiet level, and I guess it's hard to keep on-key in that context). I wound up cutting the song into about 4 sections, and pulling up the pitch separately. Now they sound like the Mormon Tabernacle Choir.

This "change length and pitch" problem sounds (!) like a bug to me.
