So I've been recording tracks in garageband but for a while i've had this problem. I record the vocals in garageband normally, as i do for all my tracks, but now when I record the vocals are softer and on the sound bar they appear red, rather than green. They also loose clarity and start crackling when i emphasise on certain words. As the vocals are recording softer I have to increase the volume of them but then this pushes them too high and they loose the quality that i previously had.
I'm pretty sure this is a garageband problem because i've tried recording vocals on audacity and sony sound forge and neither of these have the same issue. My microphone is a usb condenser, c10u samson.
