I'm hoping to use an electret mic along with an Arduino Uno to capture audio (hopefully in WAV) format, and then assign a color output based on specified ranges of frequency in order to visualize a conversation. My question is, can I use the Arduino with the mic alone to get the type of signal that I need, or do I need something like the WAVE shield from Adafruit (https://www.adafruit.com/products/94
) to pass the signal through to get the desired effect?
A bit new to the Arduino, but hoping that it can be a tool for my creative work.
Any help is appreciated.
