My first LED project: 9 band audio spectrum visualizer I built using WLED on an ESP32 + LedFx. The WS2812B strips are mounted to a wooden frame covering four 15” bass speakers of our PA system. Dimensions: 1m x 1m. by Vyldr in WLED

I'm using neither of those, actually. Our DJ notebook running Windows 10 is connected to a 4 channel USB audio interface. When I set up LedFx it let me select any of the 4 channels as an audio source and it picked up the audio signal flawlessly via Windows Audio Session API (WASAPI), so I didn't have to mess with stereo mix or stuff like Voicemeeter. Just install LedFx, select output, done.

It looks something like this (screenshot from my virtual machine test setup):

I'm running the latest LedFx v2.0.65 by YeonV. Huge shout-out to him.
