Measuring audio Answered
I have a project where I need to be able to measure 3 or 4 microphones and decide which one is getting in the loudest input volume. In other words to know who is talking around a four persons table.
Does anyone have any idea how to solve this problem? I'm using arduino (http://www.arduino.cc/) for the rest of the project so I'm able to use the arduino to measure dc voltage but how do I transfer the sound wave into a measurable dc voltage?
thx in advance / david
