Sound Sensor Output

Figure 1: output of audio sensor

As the audio input is just a value, I try to implement this to another format in order to trigger the sound localization easily and more sensitive.

This program shown the loud sound or quiet on the serial monitor.

Figure 2: multiple output of audio sensor

As calculation of time different of arrival needs two time of arrival in two different sound sensors. I try to implement two sensor input in Arduino. Since I speak near mic1 instead of mic2, "LOUD,LOUD" message will display on mic1 first. Besides, since I speak near mic2 instead of mic1, "LOUD,LOUD" message will display on mic2 first.
