Thanks Martin! I tried Opus a while ago for ambisonics, and it works well. But I had to hack the encoder so it would not combine channels together, because the default behavior is to consider multichannel streams as quadraphonic, 5.1 or 7.1 streams, with optimization for those formats, that could mess the ambisonic streams. JM. Valin (the author of Opus) wrote me that a fair amount of work would be required to optimize the encoding (and decoding) for ambisonics. So, this is excellent news, and I just subscribed to the Xiph mailing list. :-) -- Marc
