Mic array performance compared to ReSpeaker


#1

Looking for primarily a mic array platform to embed Amazon’s Alexa Voice Service into for a sleep tracker… How does the 8 mic array in the Matrix Creator compare to the ReSpeaker Mic array?

Does it feature on chip Beamforming, Noise Suppression, De-reverberation & Acoustic Echo Cancellation like the ReSpeaker…

Can’t find performance characteristics in the documentation: https://matrix-io.github.io/matrix-documentation/Hardware/API/microphone/ just get a 404…

Any response on this? I am looking to buy this primarily for the microphone array, and re-speaker seems to be more focussed on this. Anyone from Matrix can reply here? This is such a great platform. I wouldn’t want to buy something else just because of better advertising. Thanks!


#3

I’m also interested in a comparison between the two, although having (potential) Z-Wave support in the matrix creator is a definite plus for me.

It would really be great if anyone could share some insight between these two.


#4

+1 … this would be very useful information


#5

+1 for those who are undecided


#6

I have heard from a contact @ Matrix.One … that Matrix has the above capabilities mostly working for their proprietary consumer device. Will matrix.one please share the source code or libraries (to achieve above) with the developers? Especially far-field improvements. TIA for reading guys!


#7

Yes to your question. According to Matrix the following is supported

Beamforming, Noise Suppression, De-reverberation & Acoustic Echo Cancellation

Additionally, acoustic source localisation, far field vouce capture and more…

Edit: This is for the new voice product, not sure about creator


#8

Thanks, but can anyone from the company answer the initial question if the Matrix Creator has all those features.


#9

According to https://github.com/matrix-io/matrix-creator-malos/issues/87 we don’t have for instance echo cancellation on Matrix Creator.

Can we please get an overview what is implemented and what not? Otherwise one can use my 10$ microphone for the same purpose.


#10

Did anyone ever get feedback from MATRIX on this? I’m looking into the same thing and I don’t see much data on the difference between these two platforms or the more general discussion of an FPGA based system (VOICE) and an ASIC based system (ReSpeaker.)
