LED music visualizer

Hi folks!

I just saw this great tutorial about the interactive LED table (https://www.instructables.com/id/Interactive-LED-table/). Can it be modded so that music (over an external program, of course) controls the LED's? If so I would be pleased when you can explain it to me.

Thanks

must be possible if you use for example a LM3815 or LM3815. You just connect the outputs with the input of the op-ampp(not inverted input of op-ampp). Do it one by one and the leds will blink on the music
