Only Safari and IE support .aac. Here is what each browser supports:
只有 Safari 和 IE 支持 .aac。以下是每个浏览器支持的内容：
- Internet Explorer 9.0+: .mp3, .aac
- Chrome: .ogg, .mp3, .wav, .aac*
- Firefox: .ogg, .wav
- Safari: .mp3, .aac, .wav
- Opera: .ogg, .wav
- Internet Explorer 9.0+：.mp3、.aac
- 铬：.ogg、.mp3、.wav、.aac*
- 火狐：.ogg、.wav
- Safari：.mp3、.aac、.wav
- 歌剧：.ogg、.wav
* Chrome seems to support .aacbut it isn't included in the list of officially supported file extensions.
* Chrome 似乎支持 .aac，但它并未包含在官方支持的文件扩展名列表中。
I suggest using both .ogg and .mp3 or .ogg and .aac to cover all bases.
我建议同时使用 .ogg 和 .mp3 或 .ogg 和 .aac 来覆盖所有基础。

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.
AAC 音频格式似乎在大多数浏览器中被 HTML5 广泛支持，只要它在 MP4 容器中。例如，苹果的 .m4a 文件是只包含音频文件的 MP4，通常是 AAC 文件。
The .aac file itself would not be widely supported.
.aac 文件本身不会得到广泛支持。
Thus:
因此：
<audio controls="controls">
<source src="xxx.m4a" type="audio/mpeg" />
</audio>

See the browser compatibility chart - line "AAC in MP4" and footnotes.
请参阅浏览器兼容性图表 - “MP4 中的 AAC”行和脚注。
