I am trying not to add too much to the hardware configuration of my system so i have been entertaining the idea of using an electret microphone amplified to send its signal to an analog pin on my arduino then transmit that into pure data. I would like to have the frequencies register as voltages. i do not know if this is possible. I dont know much about the mechanics of how this process would work but i theorize that i should be able to create a means of converting the PWM signal from the arduino, back to something audio-ish, in PD. any insight would be much appreciated.</div>
