Decay Time. Decay time is the amount of time the microphone audio
takes to ramp down to the Off Attenuation level after Hold Time. Decay
Time values range from 0 to 5000 msec. The default value is 1000 msec.
Hold Time. This is the amount of time the microphone stays On after the
energy in the channel drops below the gating threshold. The default value
is 500 msec. The range is 1 to 5000 msec. Microphone channels gating
On and Off too frequently during short pauses in speech might be the
result of setting the Hold Time too low while too many microphones gat-
ing on at the same time may be the result of Hold Time values that are
too high.
Camera Gating Threshold. Specifies the hold time for camera gating
information.
