Live audio visualization?

So I know it's possible to make visuals react to audio in after effects. But is there a way (maybe not in after effects but a different program, or perhaps two programs working together) to make a visual react to a live audio input feed? videos like this are great (How to create Reactive Audio Spectrum Waveform Effects in Adobe After Effects (CC 2017 Tutorial) - YouTube ) but I want this to happen live at an event with music coming from a mixer into the computer and then changing the visuals on the spot. I know I could have someone on a controller effecting different parameters on visuals using other software, but I don't want that. I want the visuals to react and change live based on the audio that is being directly input into the computer. Possible or no?
