Hi Jerad,

Thanks for all  the support in the past.

 

I  need a clear picture if Analog(ECM) or digital MEMS microphones are best suited for my microphone array.

My requirements are like this.

 

I have a data acquisition and signal processing board which can support 8 microphones(say). The microphones are not fixed to the board as their positions will be different for my different experiments.At max the microphones can be around 2 feets from the DAQ and DSP board.

MY concern is that if i use the analog mic we can cable the signal to the board.But if i use digital mics then how to handle the mems mic and what all should i consider during cabling?

Is digital mics always soldered to the pcb or can be used exactly as the analog ones?

 

Thank you in advance.

 

Warm regards,
