# Turn a study recording into a quiz you can verify

> A recording is hard to review when the explanation you need is buried inside a long timeline. Upload a permitted lecture, tutorial, or spoken study summary to BrainDen, check the transcript and structured note, then use its connected quiz to test the ideas without replaying every minute.

## What this workflow gives you

### Make spoken material searchable

Use the transcript and structured note to locate definitions, explanations, and examples that would otherwise require repeated movement through the audio timeline.

### Test the explanation, not the sound

Answer questions about concepts, contrasts, sequences, and applications while the original recording remains available whenever tone or fuller context matters.

### Repair mistakes at the source

Return from a missed answer to the checked transcript, note, or relevant timestamp and connect any missing visual information from slides or handwritten notes.

## Move from a focused audio file to diagnostic questions

1. **Upload one coherent recording:** Choose an audio file with a clear topic, confirm permission, and avoid combining unrelated sessions that would make questions difficult to interpret.
2. **Correct the transcript and note:** Verify names, specialist vocabulary, numbers, formulas, and examples against the recording. Add visual context when the speaker refers to a slide, diagram, or equation.
3. **Take the quiz without replaying first:** Commit to each answer from memory, use the feedback to classify the gap, and revisit only the relevant source section before trying related practice later.

## Example: testing a recorded macroeconomics tutorial

**Input:** A 44-minute tutorial comparing demand-side and supply-side shocks, with verbal explanations of two graphs and examples of policy trade-offs.

**Possible output:**

- A scenario question asking which curve shifts and in which direction
- A comparison question about the short-run effects of two different shocks
- Feedback that points back to the checked note and flags where the graph must be verified separately

## How to get a better result

### Add the visuals the microphone missed

Spoken phrases such as “this line” or “the value here” are incomplete without the slide or board. Add that context before treating the note as quiz-ready.

### Separate hearing from remembering

Do not replay the relevant section immediately before answering. Attempt the question first, then use the audio and transcript to correct the explanation.

### Organize by course topic

File the recording note with its module and link it to the matching slides or reading so later revision follows the concept rather than a list of audio filenames.

## Frequently asked questions

### Can BrainDen turn an audio file into quiz questions?

Yes. Upload a supported audio file, review the transcript and structured note, and open the connected quiz view after correcting important details.

### Do I need permission to use a recording?

Yes. Recording and reuse rules vary by location and institution. Make sure you are allowed to record, upload, and study the material.

### What should I verify before taking the quiz?

Check names, terminology, numbers, formulas, and references to visual material against the recording and any accompanying course source.

### Can I keep the quiz with related course notes?

Yes. Store the audio-based note in nested folders and link it to the relevant lecture slides, readings, examples, or revision notes.
