Is there a way to change the BPM on a wavform to an exact BPM. I went into Edit Tempo and hit Speed Up on the presets but I don't have the exact BPM I want. Also, when I check the BPM on the changed wavform, I don't think the number it gives me is correct. Help!

Hello Dan - well, unless you have transferred a sequenced wave file (ie, from a synth/sequencer as opposed to human-played) than your BPM may not be 'exact'. However, here is a little tip from our FAQ on changing BPM and using the Stretch function...

"How can I match the tempos of two songs?
You can use Edit-Transform-Stretch to stretch the tempo of one file to the same tempo of a second file. For instance, if your first file is 100 BPM and your other file is 120 BPM, you can use the stretch function at 100/120 = 83.3333% to stretch the 120 BPM song to 100 BPM. Make sure that you have Time Stretch (preserves pitch) selected. "

I guess I'm having a brain freeze. I'm not trying to match two songs together, just change the BPM on a song from 110 BPM to 125 BPM.

I can't tell from your last post if you're still confused or not. In case you are, using your numbers it would be a edit-transform-stretch at 110/125 = 88%. Select Time Stretch to keep the same pitch, and you're good to go.

There are other settings here that you can play with to get the best sounding result; they're well explained in the help for that dialog.

Hmmm. I'm not sure what I was thinking, but I'm pretty sure it started with, "duh!". I see - you just want to change the tempo setting, not the speed of the wav file itself. Sorry I don't have an answer you can use...
