Recording from a particular channel on ReSpeaker_Mic_Array_v2.0 using arecord

Hi,

I have plugged in the ReSpeaker_Mic_Array_v2.0 to a raspberrypi 4 and trying out its out of box demo and other functionalities mentioned.

I have flashed the 6 channel firmware on the mic array and was testing it with audacity tool as mentioned in the seed wiki.
I wanted to know if there is a way we can access/record from a particular channel using arecord? if so can someone please share the command and/or steps to do that.

Thanks,
Murtuza.

Arecord can’t do that, you can write your own separate python code.
