Automixer Parameters
am_adapt_thresh Automixer Adaptive Threshold
Description
This parameter defines how much louder (in dB) the microphone's signal level
must be above its measured noise floor before it is eligible to be considered
active. Higher settings will make the microphone's gating less sensitive, while
lower settings will make it more sensitive.
am_camera_activity_time Automixer Camera Activity Time
Description
This parameter defines the amount of time (in ms) a signal must be active
before showing up on the camera activity meter. In general, it should be set
somewhat longer than the hold time of the automixer.
