    Task I want but have been too lazy - I have a favorite podcast, that I often fall asleep to. Certain parts with music etc. wake me up. I'd like to chop those parts out as automatically as possible. Can I do that here by e.g. giving some example edits to a few files, and asking to remove similar stuff from other files?

      Actually there are models for classifying sections in audio files as speech or music, for example Silero VAD or YAMNet. I am rather confident that any decent LLM can one-shot a script that downloads the model, feeds it all the podcast episodes to generate timestamps where music is playing, and uses ffmpeg to cut out those parts. For a nice touch maybe replace each music section with a few seconds of silence, add a few second fade-out to the part preceding the silence and a few second fade-in after.
