Does anyone else have problems with GarageBand squealing for about 1/20th of a second at the end of a song exported to iTunes? I can listen to the song in GB and it is fine, but the exported version (which now sits on my iPod) has a grotesque little squeal at the end. I could try to re-export it since this has happened before, but doesn't always happen. Oh, I also used iTunes to convert it to AAC 128bps if that matters . . .
