when i record a track it plays back at really low volumes. if i run a normalizer on it, the volumes come back. is this something i should do on every track i record or is there something that i am missing in my setup. i have guitar amp sm57 mbox (turn knob up to slightly before clipping. listen in headphones to make sure no clipping is present) load new track record thats pretty much what i'm doing and when i save it as a wav or mp3, and playback, the volume is really low. also, what exactly does a normalizer do?
