ESP-ADF Acoustic Echo Cancellation

Postby robertk » Thu Jul 19, 2018 12:27 am

Hey,

I recently got the ESP Lyra-T V4.3 dev board for a VoIP like communication project.

I saw on the espressif website that the board supports acoustic echo cancellation:https://www.espressif.com/en/media_over ... -solutions

However, after looking through the ESP-ADF on github I can't find any information on it. Does anyone know if its something that has already been implemented or will be implemented in the future?

Thanks,
Rob

In case there will be nothing but crickets: the Chromium source contains a C++ echo canceller for WebRTC that is supposed to be good. I don't know if its suitable for embedded usage though.

If I recall correctly, we actually use the WebRTC echo cancellation. The plan is to separate this out and release it as source code at some point, but we're not there yet.

That's good to know! Is there any form of approximate timeline for that feature?

Thanks,
Robert
