Audio Monitoring
Audio monitoring lets you listen to your production’s audio through the iPad’s speaker or connected headphones — without affecting the output stream.
Enabling monitoring
- Open the Audio Mixer panel
- Toggle Monitor on
- Audio plays through the iPad’s speaker or connected headphones/earbuds
Monitor source
Choose what you hear:
| Source | Description |
|---|---|
| Program | Listen to the on-air mix — what your audience hears |
| Preview | Listen to the previewed source — useful for checking audio before switching |
Listening to Program is the standard workflow for verifying your live output. Switch to Preview when you need to check a source’s audio before taking it to air.
Local microphone
The Local Mic toggle adds the iPad’s built-in microphone to the output mix. This is useful for:
- Adding live commentary without a dedicated microphone source
- Quick narration or announcements
The local mic audio is mixed into the program output alongside all other sources.
Test tone
The Test Tone toggle generates a continuous tone signal in the output. Use it to:
- Verify audio is reaching your streaming platform
- Check that monitoring is working
- Test audio routing and levels
Toggle it off before going live.
OSC control
Monitoring can be controlled via OSC:
| Address | Args | Description |
|---|---|---|
/pmix/audio/monitor/enabled |
int 0/1 | Enable/disable monitoring |
/pmix/audio/monitor/source |
string | Set source: Program or Preview |
/pmix/audio/testtone |
— | Toggle test tone |
/pmix/audio/mic |
— | Toggle local microphone |
Tips
- Use headphones — Monitoring through the iPad speaker during a live production can cause feedback if microphones are nearby
- Monitor program as your default — this is what your audience hears
- Check preview audio before switching to a new source, especially for sources you haven’t used recently
