That's not logical

In Logic 8, when I try to import an audio (aif) file exported from Ableton Live, Logic slows down the audio file significantly.

The track from Ableton Live was at 160bpm, and even when I set Logic's project tempo to 160bpm, the audio file plays back at less than half that tempo. I feel like I'm overlooking something really obvious, but I'm having trouble finding the solution anywhere. How do I import the audio file without Logic messing things up?

Are you doing File>Render To Disk? That should output a raw audio file taht sounds like it does in Live.

Or are you just dragging in an audio file that you've tempo-warped in Live? Live's doing the warping on the fly, so if you want the tempo to have changed, you need to render it on export.

By the way, that's from the point of view of Live 5 and Logic 8. You could also try rewiring Live into Logic.

Response by poster: I think I exported it from Live correctly, when I play the aif file in Quicktime or another audio player, it sounds fine. Only when it is in Logic does it get all messed up.

Check the sampling rate. If you're rendering in Live at 41000 and importing it in to a Logic track thats locked at 48000 you'll run in to that. It's not going to be that dramatic with this scenario. But if you're doing a 44.1 to 22 it'd be slowed down by half tempo and half pitch.

If it's sounding like it's playing at half speed, it's possible that your audio file is stereo, but Logic is treating it as mono -- thus you're hearing the samples of the two channels, interleaved. Recheck how you imported it into Logic.

Seconding mnology on the sampling rate.
