As a result, any application waiting for the audio ‘canplaythrough’ event to detect audio preloading will hang indefinitely. There are two major drawbacks caused by the limitation.įirst, the restriction prevents sounds from precaching/preloading. Safari Mobile has all the strengths and weaknesses of its desktop brethren but introduces a new limitation – all HTML5 audio must be triggered through a user interaction. If you’re looking for more advanced audio control, the Mozilla foundation is currently implementing its own version of the Web Audio API called the Audio Data API. However, Firefox 3.6′s audio support is buggy – short sounds do not play but medium length sounds (or longer) play just fine. Please refer to the Chrome section for possible ways of remedying this situationįirefox 3.6 and higher support HTML5 canvas and audio. The easiest way to address this issue is to enable partial downloading on the web server. Long sounds don’t play at all and throw an error that the sound file format is corrupted.

Unfortunately, Safari has similar drawbacks to Chrome – it doesn’t like audio served from a web server lacking partial download (ranged requests) support. Like Chrome, Safari supports HTML5 canvas and HTML5 audio, however Safari does not support the Google Web Audio API. SafariĪs Safari and Chrome are both Webkit based browsers, both share similar advantages and drawbacks. The major advantage is that the Web Audio API addresses all of HTML5 audio shortcomings by providing volume and pan controls, and real-time filtering. The major drawback is that the Web Audio API is currently supported exclusively by Chrome and only in versions 18 or higher. Every time load is called on an audio instance, the web browser will fetch the audio data from the web server.Īnother alternative is to use the Web Audio API. This will resolve the problem but increases the load on the web server.

The Balus C Code website contains an article describing one possible servlet implementation.Īnother way to circumvent this issue is to avoid using the built-in loop functionality and to use the load() function to “rewind” and play sounds again. Please note that Google App Engine does not support ranged requests, but it is possible to work around the issue by implementing a file serving servlet which supports ranged request. The easiest way to resolve this is to enable ranged requests on the web server.

  • Sound plays once then stops, but the ‘ended’ event is not fired.
  • However, HTML5 audio will only function correctly if the web server supports partial downloading (ranged requests). ChromeĬhrome version 18 and higher supports HTML5 audio and canvas. Kudos to Microsoft for getting it right (finally). Expect the IE 9 adoption rate to sky rocket when Microsoft sunsets the Win XP OS. Using SoundManager 2 will save you a lot of the headache in trying to support HTML5 audio in the older IE browsers. IE 8 and below lack HTML5 canvas and audio support so expect to fallback to DOM manipulation for visuals and Flash for audio.

    Besides, nothing beats having free third party code update and maintenance. Integration is painless, the API is clean, and it’s available under the BSD Open Source license. Currently, it’s the best Javascript sound library available. Therefore, that’s the order that we’ll be covering the browsers.Ī sidenote for developers just starting to integrate audio – I highly recommend using SoundManager 2 for the audio layer. In the mobile market, Safari (unsurprisingly) dominates the market on account of the strong iOS brand followed by Android. Internet Explorer is still the leading desktop web browser followed by Chrome and Firefox. The tables above summarize the web browser market share today (courtesy of NetMarketShare).

It is what it is, so I won’t bother retreading over the same points in this article. Much has been written about the woeful state of HTML5 audio support.
