That’s one in a series of tools and processes we wrote for Audiobook Production.

There is an error since the release of Audacity 2.2.0. You can’t select the whole track by clicking above MUTE. That graphic doesn’t exist any more. You click on the little blank spot in the lower right of the track INFO panel.
If you have reasonable recording hygiene, it should be possible to record a chapter, run it through those tools (in order) and out the door. The most likely thing to fail by far is noise. That’s why it has its own document.
Just for grins, record a test track and submit it to the forum. We will run it through the tools and see what’s what.
