How It Works
The noise gate monitors the audio input level during PTT transmission:
- Below threshold — Audio is muted (gate is "closed")
- Above threshold — Audio passes through (gate is "open")
- Threshold adapts — The gate adjusts automatically based on ambient noise levels
This means background noise is suppressed during pauses in your speech, resulting in cleaner transmissions for your team.
Enabling the Noise Gate
1
Open Settings
Go to the Settings tab.
2
Find Audio Section
Scroll to the Audio section.
3
Toggle Auto Noise Gate
Enable Auto Noise Gate. The feature activates immediately.
When to Use It
Enable the noise gate when:
- You're on a noisy set with generators, traffic, or equipment
- Wind noise is an issue (outdoor shooting)
- You're in a room with HVAC or fan noise
- Background chatter from bystanders is distracting
Disable the noise gate when:
- You're in a quiet environment
- You need to transmit ambient sounds intentionally
- You notice your voice getting cut off (the gate is too aggressive for your environment)
💡 Best Results
The noise gate works best with a headset microphone positioned close to your mouth. This creates a large difference between your voice level and ambient noise, giving the gate a clear threshold to work with.
Tips for Clean Audio
Beyond the noise gate, you can improve your PTT audio quality:
- Use a headset — Keeps the mic close to your mouth and away from ambient noise
- Face away from noise sources — Point the microphone away from generators, speakers, etc.
- Cup the mic — In very noisy environments, cup your hand around the device mic to create a wind shield
- Speak at consistent volume — The gate works best when your voice level is predictable
