# Recording

> Record microphone audio, system audio, or both. Steno captures audio locally and never uploads your recordings.

Steno can record from three audio sources: your microphone, your Mac's system audio (what you hear through your headphones or speakers), or both simultaneously.

## Microphone recording

Microphone recording is the default. It captures your voice and any voices in the same room as your Mac. No setup is required beyond granting microphone permission on first use.

Best for: in-person meetings, interviews, one-on-one conversations where you are the primary speaker.

## System audio recording

System audio capture records the audio playing through your Mac -- including the other participants on a Zoom, Google Meet, Teams, or any other call. Combined with microphone recording, this captures both sides of a virtual meeting.

**Setup (one time)**

macOS requires explicit permission for apps to record system audio. Steno uses a virtual audio driver to access this. On first use:

1. Click **Record** and select **System audio** or **Microphone + system audio**
2. Steno will prompt you to install the audio extension -- click **Allow**
3. macOS may require your administrator password
4. Restart Steno after installation

After this one-time setup, system audio recording works without any additional steps.

## Speaker labels

When Steno captures system audio, it labels lines in the transcript as `[You]` (microphone audio) or `[Others]` (system audio). This makes it easier to follow who said what in a virtual meeting.

Speaker labels appear automatically -- no configuration is needed.

## Starting a recording

1. Click the **Record** button in the toolbar or use the menu bar icon
2. Enter a name for the recording, or leave it blank (Steno will auto-generate a title)
3. Select the audio source if you want to change from the default
4. Click **Start**

## Stopping a recording

Click **Stop** in the toolbar or from the menu bar icon. Transcription begins immediately.

## Apple Shortcuts

You can start and stop recordings remotely using Apple Shortcuts and the `stenoai://` deep link scheme. See [Apple Shortcuts](/features/apple-shortcuts) for the full setup guide.
