Example
Quiz from PSY 100 lecture
A sample of what you get from a lecture recording on psychology. Yours is written from your own file.

Removing something unpleasant to increase a behavior is negative reinforcement.
How we read lecture recordings
We transcribe the audio with Whisper, which also pulls the audio track out of video files, then write questions from the transcript so you can study a lecture you only half heard.
Get the best results
- Record in mono at a modest bitrate; speech does not need music quality.
- Pair the recording with the slides for the richest set.
What your quizzes include
- Multiple choice, true or false and short-answer questions written from your material
- An explanation for every answer, plus the passage it came from
- Distractors that are plausible, not obviously wrong
- Correct answers spread across A to D, so you cannot game the pattern
How you study them
Answer one question at a time with instant feedback. Wrong answers come back later in the session, and the ones you keep missing move into your review queue.
Best for: checking you understood a chapter, quick revision before class, finding weak spots early.
Things that trip people up with lecture recordings
- Recordings over 25 MB need splitting or compressing first (a 60 minute lecture in mono MP3 at 48 kbps fits).
- Lecture-hall echo and distance from the speaker reduce accuracy. Sit near the front or use a clip-on mic.
- Apple .mov files are not accepted. Convert to .mp4 or export the audio.
