Hello!
Honestly, I did not consider this particular experiment very successful after all, and I moved on to other things. I was still learning about Nyquist and playing with toys. And I was doing things that were frustratingly expensive in computation.
But something very good did result from all my playing, though perhaps not what you need. It’s here: https://forum.audacityteam.org/t/updated-de-clicker-and-new-de-esser-for-speech/34283/1
I wrote something that automatically detects and filters out the wet clicky sounds that happen when one speaks closely into a microphone, and I have heard from many audio book narrators who are grateful for this. Also something that eliminates harsh whistling sounds that sometimes occur in sibilant consonants.
Both of these tools also have options just to generate labels rather than modifying the sounds in any way.
If you have the time and inclination, perhaps you could study the sources and adapt them toward another use. I’d like to know if it works.
