AEC SoC Support

Postby t3ddftw » Mon Jul 19, 2021 5:18 pm

Hello,

Is AEC (Acoustic Echo Cancellation) supported on all ESP32 SoCs? Specifically, does the ESP32-PICO-V3-02 support AEC?

Thank you!

It is, however you'll find the software AEC is quite lacking (aka: it's not very good). If your project needs AGC, AEC and NS and power isn't a huge concern you should do it in hardware.

Thanks! I'll have to mess around with the AEC as my microphone codec will allow me to tune down the gain substantially, so hopefully it help AEC work better. AEC hardware is expensive and not particularly suited to my needs :(.
