Hi Pratik,

As you are recording from microphone inputs, you would probably be satisfied with the performance of the Zero sound card : http://www.audioinjector.net/rpi-zero

I assume the microphones have a SNR of about 70 dB ?

The Zero is is a good fit for custom products as it is low cost and has a small footprint.

p.s. You can purchase from our shop.audioinjector.net and other places like Amazon.

Hello,
I am looking for a small sound card that is compatible with a raspberry pi 3B+, we are developing a sound sensor module using two microphones that simultaneously  process two  audio inputs. 

SIncerely,

Pratik
