Updating Microphone Script

So, I made a crappy game in 2012 in which sound from the microphone moved the game's camera forward. Only, then, to do it, I had to use a separate Processing program to do it and had three scripts capturing that input, etc. I just opened it up again and can't remember how it worked and want to replace that Processing stuff with a simpler MicrophoneInput script taking advantage of native Unity capabilities. I was a beginner in 2012 and now I'm even rustier. Would anyone be able to help me convert this script into something that relies on a built-in MicInput script?

The old scripts relying on Processing were related to these variables and scripts: UDPPacketIO, OSCReceiver, OSCscript.

Let me know if there's any help out there or if this is all too confusing to even understand! Thanks so much!
