Sparkfun has Artemis Nano board with 1 MEMS mic. And then Edge board which has 2 MEMS. Lets assume that the Edge board has a software which just combines the audio signals from the both mics. Does it result better audio quality than 1 mic on Nano board? Can you something about sound quality 1 MEMS vs 2 MEMS?
Obviously 2MEMS will be better than 1 MEMS
