Turn a long lecture or podcast recording into structured, checkable study notes

Listen to the audio I've uploaded above. This is a 55-minute university lecture on macroeconomic inflation targeting, roughly 55 minutes.

WHO'S SPEAKING
one primary lecturer, plus occasional student questions from the floor — if a speaker's identity isn't stated explicitly, use a consistent label like Speaker 1 rather than guessing a name from tone or accent.

STRUCTURE
organize by the concepts the lecturer actually covers, in the order covered, not a generic textbook-chapter outline

INSTRUCTIONS
1. Organize notes by concept, in the order the recording actually covers them — don't impose a generic outline template that doesn't match how this specific recording is structured.
2. Note vocal emphasis where it's a real signal, not decoration: if the speaker raises their voice, repeats a point, or says something like "this matters" or "remember this," flag that line in the notes as emphasized — that's exactly the kind of moment a flat transcript throws away.
3. Attribute every claim and every question to the correct speaker. In a lecture with audience questions, do not let a tentative student question get folded into the notes as if it were an authoritative statement from the lecturer — keep questions and answers clearly separated and attributed.
4. Include a timestamp on every major note so I can jump back to the original audio to verify anything that matters.
5. Where the audio is mumbled, overlapping, or a term is unfamiliar enough that you're genuinely guessing at the word, mark it [unclear ~mm:ss] rather than transcribing a confident-sounding guess. A wrong term stated with total confidence is worse for someone studying from these notes than an honest gap.
6. enough detail that someone who missed the lecture could answer a quiz on it afterward
7. Where the recording references something visual that isn't itself in the audio — "as shown on this slide," "look at the diagram I'm pointing to" — note that a visual reference was made at that timestamp, so I know a slide deck or handout exists that these notes alone can't fully capture, rather than silently dropping the reference because there's no way to describe an image you can't see.
8. If the same concept is explained twice using two different explanations or analogies (common when a lecturer notices confusion and re-explains), keep both versions in the notes rather than merging them into one — the second explanation is often there specifically because the first one didn't land for part of the audience, and losing that alternate framing removes exactly the version that might work better for someone reviewing the notes later.

OUTPUT FORMAT
Notes grouped by concept/topic with timestamps, a separate short list of anything flagged as emphasized by the speaker, a list of every timestamp where a visual reference was made without accompanying audio description, and a final section naming every [unclear] span so I know exactly what to go back and re-listen to myself.
