Audio Mixer

- Adjust individual caller volumes
- Mute/unmute specific callers
- Enable monitoring to hear callers in your headphones
N-1 Audio
N-1 mix prevents callers from hearing themselves:
- Enable N-1 in the Audio Mixer
- Each caller hears everyone except themselves
- Prevents echo and feedback
Security
Binding to Twitch
Prevent unauthorized access to call links:
- When creating a caller, toggle Bind to Twitch
- Select the Twitch account
- Only that account can join the call
Tips
Test calls before going live - Have guests join early to check audio levels and video quality.
Use N-1 audio for multi-person calls to prevent echo issues.
Position cameras consistently - Create a visual layout that works for 1, 2, or more guests.
