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.
Bluetooth headphones
Monitoring over Bluetooth headphones compensates for the headphones’ own latency, so what you hear lines up with what you’re watching. Wired headphones or the iPad speaker need no compensation.
Pre-fade listen
PFL cues one source into your monitor on its own, at its recorded level, without touching the program mix — the standard way to check a mic before you bring it up. It changes nothing your audience hears.
iPad microphone
The iPad Mic toggle adds the iPad’s built-in microphone to the output mix — live commentary or a quick announcement without a dedicated mic source. It’s a mixer input like any other, with its own fader, mute and metering; see Audio Input 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 |
|---|---|---|
/streamit/audio/monitor/enabled |
int 0/1 | Enable/disable monitoring |
/streamit/audio/monitor/source |
string | Set source: Program or Preview |
/streamit/audio/testtone |
— | Toggle test tone |
/streamit/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
