Hi. The live music tracks I've recorded with Garageband on my iMac G4 17" 1.25 sound much better than the tracks I've recorded on my iBook G4 1.2. Same instrument. Same kinda tunes. Same distance from the built-in mic. But the live recording quality coming from the iMac is much better. Does anyone have any idea why? Hard drive speed difference? Difference in built-in mic? It seems to be they should be exactly the same... Here is the kind of stuff I record just for reference in case anyone is interested: http://www.macidol.com/jamroom/bands/405/music.php If anyone has any ideas I'd love to hear 'em. Often I'm not around my iMac so I'd like to record on the iBook... Thanks!
