I am recording audio from my iPhone to my computer using the line in on my computer and the headphone jack on the phone. I use audacity to capture the sound. My question is would it be better to go through my receiver first and then to the computer using the receivers line out? I always get distortion in my recordings even though I don't let the record meter get higher than about -6db. Is it better to have the iPhone volume all the way up and the recording levels down or recording levels high and the phone volume low? Does it matter either way?
