createMasterAnalyser

Creates an analyser node connected to the master output. Use it to build visualizers, spectrum displays, or level meters.

import { createMasterAnalyser } from "@web-kits/audio";

const analyser = createMasterAnalyser({ fftSize: 2048 });

function draw() {
  const freq = analyser.getFrequencyData();
  const wave = analyser.getTimeDomainData();
  requestAnimationFrame(draw);
}
draw();
