Respeaker mic array v2 AEC and sdk

I use Respeaker mic array v2.



AEC works only at certain volumes.



How to tune distance parameter mic and speaker for AEC?

Or

Is it possible to customize the firmware for AEC?

Hi there~



For AEC parameters, there are some parameters that you can adjust at below link.

For the firmware customization, you can drop mail to techsupport@seeed.cc. thanks.
