There was a thread a while ago on how to tell people to meet the audiobook specification without becoming a recording engineer. Part of the problem is getting something to tell you what the RMS value of your voice is. No regular Audacity tool will do that.
[Graphic of clock running backwards] I’m remembering this now.
I did a speaking test using a radio show with notoriously wild sound levels and applied Chris’ Compressor with the compression setting (first option) reset from 0.5 to 0.6.

I’m betting that one tool gets you inside the ACX specifications without you knowing what “Attack and Release Times” are. I would apply this tool to one of your performances, listen to it to see what it did, submit it and see what they say. Take super good notes if they reject it.
