Well it's currently shipping so I'm doing this for better or worse

Mic array...pretty sure the tech I ordered (respeaker 6 mic) is towards the top end of DIY mic arrays so hopeful that I'll get good real life results.

Also very keen to work out whether I can use tensorflow to filter out baseline background noise BEFORE feeding the audio stream into mycroft.

Planning on launching a new blog to document my experiments and failures on this ( https://kaizen.today - not yet live cause still waiting for said tech...but SEO links and all that)

Yes, they have MEMS, looked at those a while back, was after something that I could add external mics as I need in my case and kinda ended up looking for a 5 mic input solution. Which last I looked entailed an external music input via USB unless I made something from scratch (would like to do that though wanted to work on the software and viability aspect of what I had in mind). But as that is one of my to do projects, I'll look into it again when time and resources prevail as things move fast in tech and might be something more suitable for my needs by the time I get around to this.

https://www.matrix.one/products/voice Just read about that today, no idea if better than the respeaker option - software/support/features..etc, but may be worth having a look in too.

That board actually looks pretty good too!

To my untrained eye the specs seem superior (higher SNR & sensitivity).

Respeaker appealed to me due to it being fairly mainstream. I've learned not to stray too far from the pack on SBC things. Community support & info falls off a cliff

I've used the same mic array and the provided software isn't great. In fact it's terrible, but ODAS[0] is amazing. It's super accurate, can track/isolate multiple audio sources, and has a web ui to visualize it. They also have config specifically to handle the respeaker and raspberry pi.

Amazing!

Thanks for the helpful link
