The problem with that approach is that the audio will really degrade
if you decode from speex to wav, and then re-encode to speex again.

So what you want to do is stitch the Ogg pages together (which is what
you're asking).

There's no native PHP library for Ogg yet, though some other people
have been talking about that recently.

cheers,
