0x0609 Noise Gate Parameters

Use this TLV in the Resource Create (0x0124) and Generic Card Configure (0x0122) messages to set parameters for gating noise, including:

the time constant over which the noise level is checked

the allowable noise level

noise gating sensitivity

If noise gating sensitivity is set too low for a conference, there is a risk of clipped speech; if it is set too high, there is a risk of noise bleeding through.
