EX) AEC Module

Echo Cancelling: If enabled, it estimates the echo and subtracts that estimate from the microphone signal, therefore reducing the echo in the microphone significantly without any distortion.

Noise Reduction: If enabled, it reduces the background noise in the microphone signal by the user-specified Noise Reduction Level (-40dB to 0dB, 0.1dB steps).

DC Filter: If enabled, it will remove very low frequency components of the microphone signal, which is usually just noise.

Double Talk Echo Reduction (dB): Reduces any residual echo that is left over after the Noise Reduction parameter.

Comfort Noise Generator: If enabled, it will estimate the background noise and insert the estimated noise where the echo suppressor may have removed the background noise so that a continuous audio stream is obtained. The amount of noise added is controlled by the Comfort Noise Level (-60dB to -30dB, 0.1dB steps) and should be adjusted to match the background noise in the room.

Delay: Used to compensate for long delays that may occur if the loudspeaker and microphone are too far apart.

Reset button: Resets the AEC module to its initial state.

Each of the above sub-modules can be enabled or disabled at any time during operation with changes taking effect immediately.
