Hi - I know it can be done but can't find the directions. I want to speed up my audio project a little. What's the best way? Thanks.

Working with a copy of the project so you have an unstretched backup:
 
- Select all audio tracks.
- Hit A to bring up the Audiosnap palette.
- Verify the dropdown to the right of Clip Follows Project is set to Autostretch
- Click the Clip Follows Project button.
- All clips will now show a transient icon in the upper right corner, and will follow any changes you make to the project tempo. 
- Don't go too crazy or you'll get bad stretching artifacts, although increasing tempo is usualy less damaging than reducing tempo.
- Once you got the tempo(s) you like, you will want to set appropriate Offline stretching algorithms for each clip individually in the Options section of the Audiosnap palette, and Bounce to Clips to render the stretching permanent
 
 
 

Thank you!!

Wow that worked quite well! I never wd have figured that out...thanks again.

Another option:
 
1. Wait until the project is mixed (e.g., bounce all tracks to a new track).
2. Slip-edit the end of the mixed clip with Ctrl held down (either lengthen or shorten).
3. Bounce with the iZotope Mix algorithm for maximum fidelity.
 
What I like about this approach is that you can work in segments easily. For example, I just did a song where the verses dragged a bit but the chorus felt fine. I split the clip between the verses and chorusing, sped up the verses by 2% but left the choruses intact, then re-assembled the pieces.

OK thanks.
