Automatically normalizes everyone's mic volumes to the best of it's ability, using LUFS analysis, which can be reduced even further by changing your maximum voice volume in the settings. The target LUFS level is set at -27, but after PEAK's microphone shenanigans it should be closer to about -15 LUFS - it is recommended to set your master voice volume to about 0.5, although you can make it louder if necessary. Limits the dynamic range to within 5 LUFS of the maximum LUFS level ever seen during a play session to try to avoid magnifying background noises, and uses a noise gate to muffle sound within 4 LUFS of the minimum level ever seen to deal with fan noises and bad microphones (if you see someone set to 0% volume, this is the noise gate activating).
