SoundStructure Product Family

As shown in the following figure, each submix signal from the matrix can be
processed with dynamics processing, parametric equalization, a fader, and up
to 1000 milliseconds of delay. Each SoundStructure device has as many
submixes as there are inputs.
C-Series Acoustic Echo Canceller References
In conferencing applications, an acoustic echo canceller removes the remote
site's audio that is played in the local room from being picked up by the local
microphones and sent back to the remote participants. The AEC
Local Room
in the
following figure removes the acoustic echo of the remote talker so it is not sent
back to the remote talker.
Acoustic echo cancellation processing is only required on the inputs that have
microphone audio connected that will “hear” both the local talkers’ speech
and the acoustic echo of the remote talkers’ speech.
