Does anyone have any experience with this?
Yes. The goal is to announce so your peak sound meters poke up around -6dB or so. This can mean you need to pay attention to the meters and the script at the same time. The meters can be made much larger so they're easier to see. Click and drag. The latest Audacity design has the meters changing color when you get close making them even easier to see.
-6dB is usually low enough so you don't go over (0dB) on expressive phrases and it's still reasonably loud not to have background hiss noise problems. It is a juggling act.
Many people have trouble making it up that high with a USB microphone because they tend to record low volume as a design goal. That's one of the problems with cramming all the microphone bits, parts and services into one small package.
Thank you for the clip. I'll get back to it.
As we go.
