Design in the ECS
Regarding the schematic of a system using a codec server, here is the corresponding design
which must be created with Ateïs Studio software.
The AEC component provides four independent channels. As we need one channel for each
microphones signal (if there are several local microphones) and one for the far-end signal, the using
of one AEC component is enough.
Schematic:
Design:
It's not easy at first sight, but this design is exactly corresponding to the schematic.
The AEC channel 1, linked to the local microphone use the far-end signal as reference.
The AEC channel 2, linked to the local loudspeaker use the microphone signal (far-in) as reference.
