Jean-Marc has finished the sixth Daala demo page, this one about PVQ, the foundation of our encoding scheme in both Daala and Opus.
(I suppose this also means we've finally settled on what the acronym 'PVQ' stands for: Perceptual Vector Quantization. It's based on, and expanded from, an older technique called Pyramid Vector Quantization, and we'd kept using 'PVQ' for years even though our encoding space was actually spherical. I'd suggested we call it 'Pspherical Vector Quantization' with a silent P so that we could keep the acronym, and that name appears in some of my slide decks. Don't get confused, it's all the same thing!)
