I'm working on Garageband 3 and trying to input 3 snowball usb mics for a podcast. Two of the mics are old (about 2 years) the third was purchased today. For some reason, when recording into the tracks, the new mic picks-up audio faster, causing the sound of a delay on the other 2 mics and making any podcast recording impossible. The older 2 mics are synched-up normally. The delay is less than a second, but a clear audio problem. Has anyone had this issue? Any ideas on how to fix it?
