ToneAudioBuffers

A data structure for holding multiple buffers in a Map-like datastructure.


import { Player, ToneAudioBuffers } from "tone";
const pianoSamples = new ToneAudioBuffers({
	C1: "https://tonejs.github.io/examples/audio/casio/C1.mp3",
	C2: "https://tonejs.github.io/examples/audio/casio/C2.mp3",
}, () => {
	const player = new Player().toDestination();
	// play one of the samples when they all load
	player.buffer = pianoSamples.get("C2");
	player.start();
});

import { ToneAudioBuffers } from "tone";
// To pass in additional parameters in the second parameter
const buffers = new ToneAudioBuffers({
	 urls: {
		 C1: "C1.mp3",
		 C2: "C2.mp3",
	 },
	 onload: () => console.log("loaded"),
	 baseUrl: "https://tonejs.github.io/examples/audio/casio/"
});
