Answers.Text: @beemtee: this is a very interesting project. It seems that it mostly calls out to https://github.com/cournape/talkbox for actual functionality. One can probably build what I'm looking for out of talkbot.
  
  In the meantime, I have been focusing on a hardware solution for embedding actual timecode (LTC) in the fiels during production. Here's my first pass at a decoder for that: https://github.com/arikrupnik/ltcsync

Answers.Text: Timothy Lukas H: @beemtee has it right. In the hypothetical terminal capture in my question, "0m 3.876s" represents the output of the hypothetical clappersyncoffsets program.
