vad_hangover
The hangover time is the time (in milliseconds) it takes for the VAD to switch back from speech mode to silence after the last speech frame is detected. The default value is 2000.
vad_sensitivity
The sensitivity is a dimensionless value between 0 and 100 that indicates the sensitivity of the VAD. Increasing this value corresponds to decreasing the sensitivity of the VAD (0 is the most sensitive, and 100 is the least sensitive). Higher values of sensitivity require louder audio to trigger the VAD. The default value is 43.
Applications that use the default VAD and expose the vad_sensitivity as a slider should limit the possible settings between zero (transmit all mic activity) and 70 (very selective).
vad_noise_floor
The noise floor is a dimensionless value between 0 and 20000 that controls how the VAD separates speech from background noise. Lower values assume the user is in a quieter environment where the audio is only speech. Higher values assume a noisy background environment. The default value is 576.
Note
Changes to the VAD noise floor settings do not affect currently joined channels. If the ability to change VAD settings is available to the end-user, indicate that noise floor changes only take effect in the next voice session or only allow changing the noise floor channel when the client is not in-channel.
