how can I use html5 <audio> tag to play aac file?

Question

I can get it to work in safari but doesn\'t work in chrom

Answer 1

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:

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