Currently, the FFTSpectrum example from the Sound library achieves the effect I’m looking for, but the sound it’s listening to is not. I want to know how to access the speaker output of my device and apply FFT to it in realtime, rather than the program listen to a provided sound file.

A further note…

I use “Stereo Mix” and have it enabled on my system.
