For Audio, on my litle WavePad tool, as well as a bunch of other 
choices not of interest here it gives me outputs for:

Ogg Vorbis (*.ogg) with Stero or Mono
an integer Quality from 1-10, or
a Variable Bit Rate from 96 to 224 kbps


Wave (*.wav) with
PCM and everything from
8 kHz 8-bit Mono 7kb/sec
48 kHz 16-bit Stereo 187kb/sec

For personal I usually use Raw Audio (*raw)
16-bit PCM (BE) 2-channels 96000 samples/sec/channel
(at least it tries and doesn't usually complain until I playback in 
7.1 with Sonic WIde and move the mouse).

Anyway, I have experimented some and think that with what I have, .wav 
and .ogg can be as good a quality as anything else except .raw, and I 
do like the ultrasonics.

So at least on the audio side, I say Yes for both of these as long as 
I continue to believe these are open, unencumbered forms.

Just declare that the .wav PCM and .ogg are Required to support HTML 5 
<audio> element.

I can imagine <video> being a tougher call, but that is different and 
at least we can settle the <audio> element without any big problems 
for the browser makers.

Thank You and Best Regards,
