People,<br><br>Depending on how many possible Ambisonic formats, variants, mappings do we have, things go more or less complicated. Why not just say: we encode B-Format and switch to mapping 1?<br><br>Regarding the backward compatibility:
<br><br>Most of good Vorbis players and player libraries that can do multichannel decoding (for example: Winamp with 5.1, ffdshow, mplayer, vlc) are updated so often that it's possible to release a new valuable standard and simply wait for projects to follow.
<br><br>The only thing to be considered is the compatibility of already existing hardware players, those that have Ogg Vorbis 1 support built-in and disallow users to upgrade firmware. How many of them are out there? And who uploads a 300 kbps audio file (I assume Vorbis Ambisonic WXY with q=4) to a portable player? I think before the low bitrate Vorbis Ambisonic files become popular, such hardware players will all be out of service.
