Web Audio Touch Unlock

Unlocking Web Audio - the smarter way

On iOS, the Web Audio API requires sounds to be triggered from an explicit user action, such as a tap, before any sound can be played on a webpage.

This method fixes the issue without you even having to think about it, you just pass your AudioContext instance to it and you're good to go!

You can read more about the issue and how this method handles it in this article.

Installation

npm install web-audio-touch-unlock --save

Usage

JavaScript

var webAudioTouchUnlock = require('web-audio-touch-unlock');

var context = new (window.AudioContext || window.webkitAudioContext)();

webAudioTouchUnlock(context)
    .then(function (unlocked) {
        if(unlocked) {
            // AudioContext was unlocked from an explicit user action, sound should start playing now
        } else {
            // There was no need for unlocking, devices other than iOS
        }
    }, function(reason) {
        console.error(reason);
    });

// Do all your sound related stuff here
// as you normally would like if the sound
// was never locked
// ..
var source = context.createBufferSource();
source.buffer = buffer;
source.connect(context.destination);
source.start();
// ...

webAudioTouchUnlock(context)

            // AudioContext was unlocked from an explicit user action, sound should start playing now

            // There was no need for unlocking, devices other than iOS
