Hi, this is my first post on this forum, and I was wondering if you guys could help me with a problem. Every time I record, I get a weird crackling noise on my recordings. I am running a dynamic mic through a mixer (with great preamps) to a guitar rig session i/o usb interface. it is then running into my computer (windows vista home premium 32 bit) and into my DAW (sony acid 7.0 pro). I am recording in stereo, and everything works fine, except for a weird crackling noise on my recordings. I am using a headphone output from my mixer to monitor WHILE i'm recording, and it sounds perfectly clear. but when i listen to the recording after i'm done with it through my monitors, it has the weird forementioned crackling sound. any suggestions or solutions?
