Why not read the Wikipedia Vorbis page's Technical section and follow the references to technical web pages and scholarly papers describing things further. These give a lot more detail. There's also some information in Xiph's CELT and Opus blogs regarding certain techniques (e.g. Constrained Band Energy, Band Folding, Pyramidal Vector Quantization etc.).

Actually, most of that's in the Specification. If you want to know about Psychoacoustic Models, the general principles are explained in numerous places with reference to other codecs, and most of these techniques are applicable to the tools available in Vorbis. You might also want to look into AoTuV source code versus libvorbis to spot differences in tuning. I think the libvorbis source code is probably pretty good documentation, then search Wikipedia, Google Scholar, and finally Google generally, to understand terms you don't recognise.
