<audio controls>
<source src="xxx.aac" type="audio/aac">
</audio>
I can get it to work in safari but doesn't work in chrome and firefox. any solution?
回答1:
Only Safari and IE support .aac. Here is what each browser supports:
- Internet Explorer 9.0+: .mp3, .aac
- Chrome: .ogg, .mp3, .wav, .aac*
- Firefox: .ogg, .wav
- Safari: .mp3, .aac, .wav
- Opera: .ogg, .wav
* Chrome seems to support .aac but it isn't included in the list of officially supported file extensions.
I suggest using both .ogg and .mp3 or .ogg and .aac to cover all bases.

The AAC audio format seems to be widely supported by HTML5 in most browsers as long as it is in the MP4 container. For example, an apple .m4a file is an MP4 containing only an audio file, usually an AAC file.
The .aac file itself would not be widely supported.
Thus:
<audio controls="controls">
<source src="xxx.m4a" type="audio/mpeg" />
</audio>

See the browser compatibility chart - line "AAC in MP4" and footnotes.
