I found the following proposal of Chris very interesting:
> Note: This functionality may require either defining new media type(s), or perhaps a change to the <audio> element semantics. In interactive audio, a sound is not the same as a single playable media file; typically a sound (or 'cue') is some kind of bag of pointers to multiple playable audio files, plus some selection logic and/or parameter mapping logic.
I will try to illustrate this idea for people not familiar with IA.
For example, in Safari and Opera (Firefox soon) , one can put space-structured graphics in an img element:
<img src="car.svg" alt="a car" />
and this is conform to the semantic of the img w3c spec
Will be nice to be able to put time-structured audio (cue if using iXMF vocabulary) in the audio element:
<audio src="beach_music.ixmf" alt="music at the beach"/>
with a beach_music file like this one:
<cue id="beach_music" loopCount="-1">
<chunk pick="exclusiveRandom">
<sound src="/loop_1-1.wav" pickPriority="2"/>
<sound src="/loop_1-2.wav" pickPriority="2"/>
<sound src="/loop_1-3.wav" pickPriority="1"/>
</chunk>
<chunk pick="exclusiveRandom">
<sound src="/loop_2-1.wav" pickPriority="2"/>
<sound src="/loop_2-2.wav" pickPriority="2"/>
<sound src="/loop_2-3.wav" pickPriority="1"/>
</chunk>
<panControl>
<animate id="slide" attribute="pan" begin="beach_music.start" from="-100" to="100"/>
</panControl>
</cue>
