Apple Logic Pro /LogicExpress Discussion

I'm having a problem working with imported .wav files (in L7).  These files play normally in 
other audio apps such as Quicktime, but when imported to a Logic audio track, the tempo 
of the audio playback doubles (or faster, perhaps), so that recorded audio sounds like a 
tape playing in fast forward or rewind speeds.  Adjusting the tempo of the sequencer has 
no effect on this.

I can't seem to find a way to fix this in Logic.  There is the workaround of converting .wavs 
outside of Logic and importing as aiffs or mp3's. That seems to work, but it's more 
arduous.  Can anyone shed any light on why this may be, and is there any way in Logic to 
adjust the 'tempo' of audio sample playback?

Hi Michael.  Check your sample rate.  If they're playing fast then 
you need to change the sample rate in the Audio menu to match 
whatever the waves are at.  Chances are the wavs are in 48 and your 
project is in 44.1.  Or vice versa, my brain's fried.  There's also 
the option when you import them to convert the waves to the sample 
rate your project is in.

Thanks, all.  Actually I had figured it out before your reply (before 2:00 AM my time! zzzz)
The original wavs were recorded at a 22 mhz rate.  After much searching through the 
reference pdf's, I finally found the sample rate conversion tool (in the audio sample editor, 
the window that shows the waveform - a menu item there).  That did the trick.

Thanks again.
