Improve sound quality when recording


I’m trying to improve the sound quality of my recordings with the Respeaker Core v2.

I’m using the Debian image 20180801.

I plugged a Respeaker Mic Array v2 into the USB port to compare.

I’m very impressed by the the recording I get using it: the noise cancellation is very good and the recording quite loud.

I am not getting the same result with the Respeaker Core microphones.

Should I implement the Librespeaker library to get similar noise activation and recording gain?

Will I ultimately get the same quality outcome?

Thanks for your help
