Hi,

We recently bought the Seeed ReSpeaker 4 mic linear array (https://www.seeedstudio.com/ReSpeaker-4-Mic-Linear-Array-Kit-for-Raspberry-Pi-p-3066.html) and had a few questions about it. What kind of audio processing (e.g. acoustic echo cancelation, beamforming, noise suppression etc) does it implement out of the box? When we tried to record audio using it, it seemed to output the raw signals for the 4 microphones. If it does come with audio processing, could you please let us know how to enable it?

If it doesn’t come with firmware for audio processing, do you recommend any software which is tested to work on it for audio processing?

Any help from you will be much appreciated.

Thanks,
Neerad
