How to play a notification sound on websites?

问题

When a certain event occurs, I want my website to play a short notification sound to the user.

The sound should not auto-start (instantly) when the website is opened. Instead, it should be played on demand via JavaScript (when that certain event occurs).

It is important that this also works on older browsers (IE6 and such).

So, basically there are two questions:

What codec should I use?
What's best practice to embed the audio file? (<embed> vs. <object> vs. Flash vs. <audio>)

回答1:

This solution works on pretty much all browsers (even without Flash installed):

<!doctype html>
<html>
  <head>
    <title>Audio test</title>
    <script>
      /**
        * Plays a sound using the HTML5 audio tag. Provide mp3 and ogg files for best browser support.
        * @param {string} filename The name of the file. Omit the ending!
        */
      function playSound(filename){
        var mp3Source = '<source src="' + filename + '.mp3" type="audio/mpeg">';
        var oggSource = '<source src="' + filename + '.ogg" type="audio/ogg">';
        var embedSource = '<embed hidden="true" autostart="true" loop="false" src="' + filename +'.mp3">';
        document.getElementById("sound").innerHTML='<audio autoplay="autoplay">' + mp3Source + oggSource + embedSource + '</audio>';
      }
    </script>
  </head>

  <body>
    <!-- Will try to play bing.mp3 or bing.ogg (depends on browser compatibility) -->
    <button onclick="playSound('bing');">Play</button>  
    <div id="sound"></div>
  </body>
</html>

Browser support

<audio> (Modern browsers)
<embed> (Fallback)

Codes used

MP3 for Chrome, Safari and Internet Explorer.
OGG for Firefox and Opera.

回答2:

As of 2016, the following will suffice (you don't even need to embed):

let audio = new Audio('/path/to/audio/file.mp3');
audio.play();

How about the yahoo's media player Just embed yahoo's library

<script type="text/javascript" src="http://mediaplayer.yahoo.com/js"></script>

And use it like

<a id="beep" href="song.mp3">Play Song</a>

To autostart

$(function() { $("#beep").click(); });

Play cross browser compatible notifications

As adviced by @Tim Tisdall from this post , Check Howler.js Plugin.

Browsers like chrome disables javascript execution when minimized or inactive for performance improvements. But This plays notification sounds even if browser is inactive or minimized by the user.

  var sound =new Howl({
                     src: ['../sounds/rings.mp3','../sounds/rings.wav','../sounds/rings.ogg',
                           '../sounds/rings.aiff'],
                     autoplay: true,
                     loop: true
                    });

               sound.play();

Hope helps someone.

Use the audio.js which is a polyfill for the <audio> tag with fallback to flash.

In general, look at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills for polyfills to the HTML 5 APIs.. (it includes more <audio> polyfills)

var audio = new Audio('audio_file.mp3');

function post()
{
  var tval=document.getElementById("mess").value;   
  var inhtml=document.getElementById("chat_div");
  inhtml.innerHTML=inhtml.innerHTML+"<p class='me'>Me:-"+tval+"</p>";
  inhtml.innerHTML=inhtml.innerHTML+"<p class='demo'>Demo:-Hi! how are you</p>";
  audio.play();
}

We can just use Audio and an object together like:

var audio = {};
audio['ubuntu'] = new Audio();
audio['ubuntu'].src="start.ogg";
audio['ubuntu'].play();

and even adding addEventListener for play and ended

回答9:

I wrote a clean functional method of playing sounds:

sounds = {
    test : new Audio('/assets/sounds/test.mp3')
};

sound_volume = 0.1;

function playSound(sound) {
    sounds[sound].volume = sound_volume;
    sounds[sound].play();
}
function stopSound(sound) {
    sounds[sound].pause();
}
function setVolume(sound, volume) {
    sounds[sound].volume = volume;
    sound_volume = volume;
}
