Dear Enrico,
No, I don't have it sorry, but surely there may be tools to extract the text from it.
Anyhow, it is very easy to
generate these podcasts, more or less specialized on different aspects of Harbour/xHarbour:
1. go to
https://notebooklm.google.com/ (free)
2. create a new notebook and add sources to it. You can directly provide GitHub URLs to the Harbour/xHarbour modules.
3. Select the language to use: In example for spanish use "El podcast está orientado al público hispanoparlante. !IMPORTANTE hablad en español!"
4.
Generate it.
Its great to analize single modules, or a bunch of them!
