ERL + ERLE Meter
Shows the total ERL and ERLE reduction. This is an average meter that updates only when a receive -only signal is
present.
PTT (Push to Talk) Mode
Select the Enable Push to Talk Mode checkbox to enable PTT. PTT notifies AEC when a microphone is switched
off, and freezes AEC convergence until the microphone is switched back on. As a result, PTT helps prevent AEC
divergence and improves overall AEC performance with push to talk microphones.
When the microphone is off, set the PTT Threshold slider to the level of the Pre-Gain Meter for the channel.
