Waveform (in some way)

I finally took the time to figure out the math behind creating a 'waveform', i say in quotes as this waveform uses the audios Db levels rather than Amplitude which is (to my limited understanding and quick googling) what waveforms are actually built from. However, i believe this can still be useful for some audio! Unfortunatly Godot has no way to access Amplitude. Please note, if you hide the waveform, it will not be processessing (not building its peaks). Please also note, peaks build from the top down, i may change this in the future but for now it is this way (plz, no more math, plz) Here is a video of the peaks being built! :D
