Subject:Changing the tempo of a individual sound?

How do you change the tempo of a single sound to match with the rest of a project. I'm trying to match a loop of a voice to match with my project. i need to speed just that one loop up to be in sync with the rest. thanks

There are a number of ways to do this. One would be to cut the vocal up into little segments and rearrange the timing that way. Another would be time compression. BTW, is the vocal loop acidized? That does change things sometimes.

i think it is acidized.

If it's ACIDized properly, it should match the project's tempo.

If the sample is not ACIDized, then ACID will try its best to fit the sample within the correct tempo (based on its length). However, ACID sometimes doesn't do it correctly. A sample you intended for 8 beats might be identified as 4 beats by ACID (which would double the tempo you intended).

If you need to ACIDize the sample correctly, what you could do is something like DKeenum mentioned but instead change the track properties of the sample to "One-shot" and then set the Loop Region over the sample and render to a new track.

What this will do is ACIDize the sample with the project's tempo and key information.

Alternatively, you can also use Sound Forge's ACID loop creation tools but it's a bit more involved as you must know the correlation between length of the sample and tempo if you expect results. (For example, a 4 beat sample that's exactly 2 seconds long will fit within a tempo of exactly 120 BPM.)
