I’m using Windows 10. I am narrating a title for ACX.com. The sample recorded as usual and seemed all right when I was watching the levels during playback and editing, but they subsequently informed me the test upload was too low a level. I can’t pull it now but somewhere, I think around 24 bB. They want it is 1.2dB. I have no idea where to adjust this in Audacity.

Meters are not as reliable or as convenient as “scanning” the whole file at once with ACX check (or similar). And, Audacity doesn’t have an RMS meter built-in.
RMS is a kind-of average that roughly corresponds to loudness. The peak levels don’t correlate well with loudness and the limits are to prevent [u]clipping[/u] (distortion). (The ACX peak dB requirements are “over cautious” but they are requirements.)
RMS Normalize is a linear volume adjustment. The RMS, peak, and noise levels all change up or down by the same amount (usually up). The limiter “pushes down” any peaks above the threshold with almost no effect on the RMS level or perceived loudness.
just FYI - dB is a “level” or “amplitude”, not a “rate”.
Normalize adjusts the tips of the blue waves. RMS Normalize adjusts the loudness. There are not that many tools that work in loudness and special ones had to be designed so we could help people with audiobooks. Same thing with ACX Check. There are ways to measure your voice file success without that, but they’re pretty scary.
The more you tell us about how you’re reading, the faster we can get you rolling. Which microphone do you have and how do you have it connected? What’s your recording room like? Are you following somebody’s YouTube posting or other instructions?
Are you a voice performer with or without the microphone? Real Life Actor? Are you the author?
It can make a world of difference if we can hear you perform.
So you could stop right there. No other tools. However, you don’t pass noise by all that much and I would add very gentle noise reduction of the beast, 6, 6, 6.
The voice is very hard and crisp. That would give me a headache if I had to listen to a book in those tones. Does it sound aggressive to you? I suspect strongly if I brought down the crispness a little, enough of the background hiss noise would go with it and you wouldn’t need the noise reduction.
I’m going to mess with it a bit. The published Audiobook Mastering is usually the simplest way to get to a working submission. These are the wiki supporting documents.
The other mic switch isn’t compression, its a rumble-filter which cuts back the bass.
You should turn-off all Windows real-time effects, as they change the sound before it gets to Audacity
see … https://youtu.be/sxnUjiGgBaI
(disable all “enhancements” on both the recording & playback tabs on Windows sound control panel)
I don’t know of any Windows effects that can give a harsh tonal boost like that. Treble turned up and Essing. You could cut wood with that sound.
You may run into an odd production problem. You can’t change microphones in the middle of a book. So whatever you decide to go with, you’ll be going with it for weeks or however long it takes you to read.
