Urgh, so you didn't really know but felt obliged to share it anyway. > but I > heard that Vorbis has to go through some difficulties because of patents on > this side (something with Ambisonics or something). No. We have a multichannel system somewhat unlike other encodings. There were no patent issues. I didn't choose our method because of any patent issues. I chose it because it scaled to low bitrate nicely without mucking up any of the encoding model. Ambisonics had nothing to do with that and is optional/compatible with our channel encoding scheme. That said, Ambisonic's patents expired long ago and it's one reason Ambisonics is an attractive surround encoding. Full spherical, including up/down, in four channels, decoding into between 8 to 16 speakers with speaker placement not critical like in 5.1/7.1. > This is what I heard > from some knowledgable Vorbis people :) They don't sound very knowledgable to me.
