I am grateful that, in spite of your low opinion of me, you responded with help. But please allow me to correct some misperceptions.
First, I did search the Vorbis site and found nothing. I must have been looking for the wrong keywords because all I found was information about compression formats. So I suppose I didn't search it well enough, but it wasn't for not trying
The second thing is that I have no idea how to search wikipedia for a page with audio on it. I did search wikipedia for Vobis and ogg, but I found nothing. I did find an example on the tutorial page you just mentioned, and I like it. Can you tell me how to find a wikipedia page with audio?
Anyway, I am grateful for you patience, but your assertion that I didn't "bother to look" is simply not true.
