Non Linear Process (NLP)
The microphone captures the sound coming from the loudspeaker and also
the speaker's voice.
If on the microphone capsule, the sound pressure
level of the loudspeaker sound is near of the sound
pressure level of the speaker's voice, then the AEC
component won't be able to recognize them. In this
case the AEC process is stopped and the non-linear
process is activated.
All you have to do is to choose the type of the non-
linear process, soft, medium, aggressive or off.
The NLP threshold parameter is not available, the threshold is now automatically set.
