Hey! A noise gate would be handy, but in the meantime you can definitely make a noise gate on a mixer group and it’s actually pretty simple! It involves creating a global parameter that will be driven by a sidechain on the mixer group. I just experimented and here’s the settings I came up with but you might want to play around with the threshold or even make the threshold user-tunable in your game’s settings.
- Create a side chain on your group bus before the fader.
- Open the Preset Browser window and create a new global parameter, range 0-1, initial value 0 (edit, used to say 1).
- Try setting the sidechain’s values as in the image below, but you can experiment.
- Right-click the volume on the group’s fader and click Add Automation. Click Add Curve at the bottom left and add a volume ramp. The Threshold works like this: anything above the right edge (-22.5dB in the example) will not cause the fader to dip. Once it crosses that threshold, it will ramp down till the incoming audio hits -35dB (for example) at which point the fader will be at -infinity dB.
EDIT: Step 5. Right-click on the parameter value (in red in the example image), Add Modulation, then add the side chain you created to the Input. Adjust the settings similar to what’s depicted in the image. A quick attack will keep the voice getting chopped at the beginning of incoming audio, and the longer release will tame down the jittery artifacts while it’s fading out through the threshold range.
