Why down to 4 mics when Respeaker v2 has 6?

I see this array has a suggested distance limit of 3 meters, and 6 mic ReSpeaker 2.0 has ~5 meters.

Why was the new mic array lowered to 4 mics when the old one had 7?

Hey! Where did you see 3 meters? It should be 5 meters. Let me know and I can correct this mistake.

The new Mic array v2 uses the XMOS XVF3000 chipset. This has improved onboard DSP that allows for less microphones but still a even greater performance.

@seth.welday how does that work. How were you able to achieve better performance with less microphones?
