Omg long post. TLDR from an LLM for anyone interested

Speed your audio up 2–3× with ffmpeg before sending it to OpenAI’s gpt-4o-transcribe: the shorter file uses fewer input-tokens, cuts costs by roughly a third, and processes faster with little quality loss (4× is too fast). A sample yt-dlp → ffmpeg → curl script shows the workflow.

This is the sort of content I want to see in Tweets and LinkedIn posts.

I have been thinking for a while how do you make good use of the short space in those places.

LLM did well here.
