Sorry, I wanted to say that "I am NOT expert about arduino and sound circuits".

Hello vasquo

Thank you for the answer.

I didn't found it do buy too, but I intend to mount that circuit. Moreover, I am not sure that it will be useful to make an Arduino based audio decibel meter. And I have some doubt about the conection to arduino and to the microphone. Because I am expert about arduino and sound circuits. If you or someone here in our community could help me with any tip, I would be so grateful.

Hello

I am searching for a solution about make an decibel meter based on arduino, and I found the circuit of Philips- NXT: AN 1991, that is an Audio decibel level detector with meter driver. I would like your opinion about it.
