Firstly, I am rookie.
I am doing a project that needs to collect sound signal from multiple microphones and figure out which one has the greatest amplitude.
The microphones I am using are surface-mount microphones and I've built the necessary amplifier circuits...now I need a shield/circuit that can produce the envelope of the wave form and change the +/- output voltage to a 0 to 5V output...
Some ppl recommend me to use the Shifty VU shield, but the problem is the output of the microphone is a pin output, not a audio jacket...
Does anyone has any better recommendation for shields/circuit?
