Psychoacoustic model in Vorbis

I read Vorbis1 specification.

There are things about decoding in that.

However I want to know about encoding.

Especially, about use of PAM(psychoacoustic model).

MP3 uses it to calculate masking threshold, but I don't know how Vorbis does use PAM.

In floor? or In channel coupling?

How about looking at the source?

I think that requesting e-mails on a public forum is extremely impolite, since it undermines its purpose completely.
"To understand me, you'll have to swallow a world." Or maybe your words.

If my request is impolite, I apologize.

There are many papers about MPEG audio.

But I can't find papers about Vorbis.

So I thought "someone has Vorbis articles like MPEG"

Because Vorbis is patent free, I thought "developers also can distribute encoding informaions free"

If my thought is a fault, I'm sorry.

In the present condition, the source code of a Vorbis encoder thinks that it is the substantial only textbook.
I also regard reading various comments of that as becoming helpful.
