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 gating 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 infor-
mation.
