I can't import some audio files from my computer to Logic, They play in iTunes but when I import them to logic , the regions become black almost and have no sound. Other wav's files play normally. What's the problem?


Logic Pro, Mac OS X (10.7.1)

What you could try is Copy/Convert (using the Local Menu in the audio Bin) those WAVs to AIFF, and see if the problem persists. Also, I heard of a similar problem which went away when Logic was set to 64 bit mode. You could try that too.

WAV and AIFF are both PCM formats, meaning their audio is "binarized" almost identically, the main differences are in the few hundred bytes of info that form the file header. WAV is the "native" audioformat for DOS/Windows based machines, AIFF is Apples' "native" audioformat. Sometimes WAVs' made in Windows have small incompatibilities in their file header, which disappears/gets rectified when converted to AIFF.

    What type of audio files? What bitdepth and samplefrequency?

    .WAV / 24 bits 48khz. Logic do suport this kind of flie. I do import some files, later the same files was becoming gray and not playing when I drag them to arrange windown. This not happen to all my wavs but with somes my friend gave me, he recorded at other studio.
