I’m disputing the “is too low” comments. It’s supposed to be like it is now, because of audio physics. The recording is at least -18dBFS. One might find that low, but it’s not wrong.
The fact that everyone thinks 0 is 0 on any meter or recording, is a misconception. That’s what I’m trying to explain here in simple form. If anyone want details, check Reti’s comments.
Again, I’m certainly not against a level control if someone wants it. I’d probably use it too.
FWIW. See below for a simple metering overview. VU is a mixer. dBFS is a recording:
