I've read a lot about gain when you have multiple inputs, it's best in a digital setup to keep it well under 0.
I can't find anything about a single input though, which is what I'm recording for some instructional videos.
My mic is only giving me an average of -30dB, much lower than the ideal -18dB. So the volume or gain need increasing.
If I only have a single input, is there any difference between boosting gain when recording, and just increasing the volume in my editing program (DaVinci Resolve)?
Is 1 better, or how are they different?
