Class AudioAnalyser

Create a AudioAnalyser object, which uses an AnalyserNode to analyse audio data. This uses the Web Audio API.

Example

// create an AudioListener and add it to the camera
const listener = new THREE.AudioListener();
camera.add(listener);
// create an Audio source
const sound = new THREE.Audio(listener);
// load a sound and set it as the Audio object's buffer
const audioLoader = new THREE.AudioLoader();
audioLoader.load('sounds/ambient.ogg', function (buffer) {
    sound.setBuffer(buffer);
    sound.setLoop(true);
    sound.setVolume(0.5);
    sound.play();
});
// create an AudioAnalyser, passing in the sound and desired fftSize
const analyser = new THREE.AudioAnalyser(sound, 32);
// get the average frequency of the sound
const data = analyser.getAverageFrequency();
