volume level.
If you want to modify the volume of a source (near-end inputs), then you have to use the "Near-End
Level" knobs in the AEC component. When the system is properly adjusted, it is not advised to
change the volume by using another parameter than this one.
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.
