Hear the sound of what the venue is showing, on your own headphones.

MAD Relay brings the live audio of a venue (a hall, a bar, an event space) to your phone, in sync with what you see.

1. Install MAD Relay (free).
2. Scan the venue's QR code. With your phone's camera, or within the app.
3. Put on your headphones, then tap PLAY.

Headphones (wired or Bluetooth) are needed: by design the app does not play through the phone's speaker.
