Re: STICKY: The I2S sound thread.

Heya all

Is it possible to run 4 digital Mems mics off any Pi board ?

as i understand it's 2 mics to an I2S channel so you would need 2x i2s required, if thats correct :/

thanks !!!

Multiple digital microphone input


i was wondering if the raspberry pi is capable of recording a quad digital audio feed from 4 microphones ?

My understanding is that general these an I2S channel on boards/MC but they can only support 2 microphones at once, so to fix that issue 2 x I2S channels would be needed.
