I used phatbeat and love its audio-visualitation capabilities.
Thank you!
Have a look at this, found it with a Google search. I have a Blinkt on my Pi 4 showing CPU load.
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <wiringPi.h>
#include <wiringPiI2C.h>
#include "../pivumeter.h"
#define DAT 23
#define CLK 24
#define NUM_PIXELS 8
static unsigned int pixels[NUM_PIXELS] = {0,0,0,0,0,0,0,0};
static void blinkt_set_pixel(unsigned char index, unsigned char r, unsigned char g, unsigned char b, unsigned char brightness){
pixels[index] = (brightness & 31);
pixels[index] <<= 5;
pixels[index] |= r;
pixels[index] <<= 8;
pixels[index] |= g;
pixels[index] <<= 8;
