Is there a way to export the .srt file for the audio clip?

Or provide the timestamp for each section of the transcripts?

Check "4 - Subtitles" example scene which creates and playback subtitles for audioclip. It doesn't serialize them to .srt, but this should be easy to add.

Alternatively, you can use original whisper.cpp main.exe with "-osrt" flag to transcribe audio file to .srt.
