Spectogram Voicemeeter

A real-time(-ish) audio spectrometer using PortAudio and KissFFT.

It captures audio from Voicemeeter B1 output and visualizes a spectrogram of frequencies in a window

• Can be changed to suit any channel that portaudio can read the stream from.

(NOTE: making the window wider has a bug I could not find a way to fix)
