16.2.1 Acoustic Echo Cancellation
The AEC includes:
â– A referenced sub-band adaptive linear filter that models the acoustic path from the receive reference point
to the microphone input
â– A non-linear processing function that applies narrowband and wideband attenuation adaptively as a result
of residual echo present after the linear filter.
16.2.2 Noise Suppression with Wind Noise Reduction

The equalisation filters:
â– Are independent in the send and receive signal channels
â– Are independently enabled
â– Are configurable to achieve the required frequency response
â– Each channel comprises of 5 stages of cascaded 2nd order IIR filters
â– Compensate for the frequency response of transducers in the system, i.e. the microphone and loud speaker
