Ambisonic credentials

I have joined this Wiki because it looks like you guys have an interest in Ambisonics. I can help with this. I have been following Ambisonics since 1977, and have owned an Ambisonic decoder (a Minim AD 7) since 1994. I also created and maintain the Ambsonic Surround Sound FAQ. More recently, I was involved in defining the ".amb" and ".uhj" specifications for dowloadable B-Format and two-channel UHJ files. However, I do not work in pro-audio; I am just a domestic listener.

Ambisonics on XiphWiki

I found that the Ambisonics page on this Wiki had been marked for deletion. I removed this, and created a page discussing some of the problems of handling Ambisonic B-Format and UHJ format in the future. I also discuss how to perform channel conversions from Ambisonic B-Format and UHJ to Mono and Stereo. Finally I discuss 5.1 and G-Format.

External resources on Ambisonics

• There is now a set of Wikipedia articles on Ambisonics.
• Of particular relevance is the ".amb" specification for downloadable B-Format files. There are currently over 75 pieces available in this format for free download. Most of these are first-order full-sphere soundfields. The ".amb" spec has some limitations which it would be useful to overcome.
• There is also the ".uhj" specification for downloadable two-channel UHJ files, although it is not currently in use. The ".uhj" spec also has some limitations which it would be useful to overcome.
• My website has many pages on Ambisonics (including at the bottom links to other Ambisonic websites).
