Var canPlayOgg = !!myAudio.canPlayType & "" != myAudio.canPlayType('audio/ogg codecs="vorbis"') Var canPlayMp3 = !!myAudio.canPlayType & "" != myAudio.canPlayType('audio/mpeg') Currently canPlayType(type) returns: "", "maybe" or "probably" Var myAudio = document.createElement('audio') will be thrown for those browsers that don't support it Or check file type compatibility: // Need to check the canPlayType first or an exception Var audioTagSupport = !!(document.createElement('audio').canPlayType) Using JavaScript, you can check for audio tag support: // returns a boolean To demonstrate this "feature sniffing", we've created a rough and ready HTML5 audio checker. We could use browser sniffing, but considering the rapidly changing landscape, it's better to check what capabilities a particular browser supports and adapt accordingly. If we intend to take advantage of each browser's audio capabilities, we need to create different solutions for different browsers.

If developers want to take full advantage of all browsers that support HTML5 audio, they'll need to create both MP3 and Ogg versions of the audio file they want to stream! JavaScript solutions The most significant issue is the cross-browser implementation, where lack of a common supported audio format among browsers causes complications. With growing support for HTML5 in modern browsers, we were inspired to break our Flash dependency and use native audio when it was supported. The original jPlayer relied on Flash to play the actual audio while allowing the look and feel to be styled via HTML and CSS. Many relied on Flash to implement the player's graphical interface, effectively isolating the player from the rest of the web design process. When we created jPlayer, an audio player plugin for jQuery, we were attempting to address some of the limitations of the current crop of Flash-based audio players. At the time of going to press issues have been reported with older versions of Firefox and Mobile Safari. One caveat, though: you may need to be careful about the order of the elements. In addition, we can embed a Flash player if all else fails: The browser will try to load the first audio source, and if it fails or isn't supported, it will move on to the next audio source. The best way to coerce browsers into playing audio (or video, for that matter) is to use the element.

buffered() - attribute that specifies the start and end time of the buffered part of the file.

canPlayType() - interrogates the browser to establish whether the given mime type can be played.

To create our own controls, we can use the API methods defined by the spec: You'll need to replace the Ogg file with an MP3 to get it working in Safari and Internet Explorer 9+.)įor a list of which codecs are supported on which browser (which may differ depending on device) see our article HTML5 Audio - The State of Play. (This example will work for the latest versions of Firefox, Chrome and Opera. Let's take a couple of these attributes and create a simple example that will play an audio file: Incidentally these are the same attributes defined for the element.

preload - none / metadata / auto - where 'metadata' means preload just the metadata and 'auto' leaves the browser to decide whether to preload the whole file.

controls - a boolean specifying whether the browser should display its default media controls.

loop - a boolean specifying whether the file should be repeatedly played.

autoplay - a boolean specifying whether the file should play as soon as it can.

src - a valid URL specifying the content source.

According to specĬurrently, the HTML5 spec defines five attributes for the element: For browsers that don't support audio natively, we can easily fallback to Flash.

We can take advantage of this now as all of the major browsers support it - currently Firefox, Chrome, Safari and Opera, and Internet Explorer 9+. One of the most exciting and long-awaited features in HTML5 the element, enabling native audio playback within the browser. Although Adobe's Flash player is unquestionably the most ubiquitous of these, most developers and designers would agree that it's better not to rely on a plugin at all. Until recently, the ability to play any type of audio within a browser involved using Adobe Flash or other browser plugins. This article was last updated on to reflect changes in the spec.
