[Bug 14817] There is no required audio or video codec in the specification. However, I think that recommending the use of the AU file format to be supported by <audio> would be a good idea, since none of the vendors have patent issues with the format.

The point I (the submitter) was making is that AU (.au/.snd) is a good baseline
file format for audio that is well established, and is not difficult to
implement.

Although a better-compressed, more feature-rich audio codec might/will
eventually be agreed on by browser vendors, I think the AU file format (or
perhaps another, similar format such as WAV-wrapped PCM) would provide a
baseline format that all browsers could support.
In other words, AU would be to OGG or MP3 as BMP is to PNG. 

The format has been in use for years on all three major platforms (although
particularly Linux/Mac), and there are plenty of tools, open-source and
otherwise to play back and convert AU format files. Additionally, two browser
vendors, Apple and Microsoft, already produce software that plays AU (QuickTime
and WMP, respectively), and AU is a de-facto standard for UNIX audio.
