AEC and playback quality


As of today, the Respeaker Mic Array v2 AEC algorythm is limiting the audio/music playback to 16Khz (the 48Khz firmware has pretty bad AEC).

It seems that WebRTC AEC algorythm allows a sample rate up to 32Khz.

Do you think you can increase the playback sample rate to 32Khz and keep the AEC performance identical to the 16Khz one (which would greatly improve music playback quality while preserving AEC performance)?

Can you check with your software guys to see if this is at all possible?


Hi there~

We checked with software team that it can NOT be acheived due to XMOS calculation resource limit. thanks.
