with higher priority.

The purpose of this feature is to keep natural room sound in the
signal so that meeting participants on the far end know the audio
signal has not been interrupted.
•Off Attenuation
Sets the level of signal reduction when a channel is not active
•Hold Time
Sets the duration for which the channel remains open after the level
drops below the gate threshold

Gating Sensitivity
•Gating Sensitivity
Changes the threshold of the level at which the gate is opened
Generally set between 2~5.
You can start testing from 2.
Find the most appropriate effect for your meeting space.
The higher the number, the more sensitive the trigger of Voice will be,
and the chance of Camera switch will be relatively increased.
This parameter will affect the sensitivity of voice tracking, and can also
avoid some low-volume interference.
