# Audio Recording & Transcription

Capture voice memos and lectures, and automatically transcribe them to text offline inside your browser.

## Recording Audio

1. Open any note in the editor.
2. Click the **Record Audio** microphone icon in the editing toolbar.
3. Grant the browser permission to access your microphone.
4. Speak into your microphone. You will see a live waveform visualization showing the recording level.
5. Click **Stop** to finish recording.

## Client-Side Transcription

After stopping a recording:
- Basalt starts a browser-native transcription worker.
- The audio is processed entirely on your local machine using an optimized WebAssembly model (no voice data is sent to a server).
- Once complete, the transcription is appended as text to your note, and the original audio file is saved as a local attachment.
