Interesting (in its way), looks like a combo of HOA Ambisonic scene
description (using multiple HOA streams possibly of different orders)
and bandwidth compression; i.e. there is an encoding and decoding device
as part of the application, as there would need to be, given that
patents ultimately have to describe a device. It is indeed also a file
format, which I would not have thought was patentable as such, but maybe
anything is possible these days. The description includes in the first
paragraph:
"The B-Format (based on the extensible ^iff/wav' structure) with its
*.amb file format realisation as described as of 30 March 2009 for
example in Martin Leese, "File Format for B-Format ", http://www.
ambisonia.com/Members/etienne/Members/mleese/file-format-for-b-format,
is the most sophisticated format available today.
"
I guess I haven't played the system well enough - as the person who
first published the amb format (not in 2009 but in 2000, in my paper for
ICMC Berlin) it would have been a nice addition to my meagre CV to have
been mentioned in a patent application. Perhaps I should write to them.
The authors I think are probably known here, their names appear
regularly at conferences etc:
KEILER, Florian; (DE).
KORDON, Sven; (DE).
BOEHM, Johannes; (DE).
KROPP, Holger; (DE).
BATKE, Johann-Markus; (DE)
So is this, in fact, the ultimate file format that folk on this list
have been arguing for (and over) for so long?

Hi,
Just noticed this the other day:
WO2012059385 DATA STRUCTURE FOR HIGHER ORDER AMBISONICS AUDIO DATA
http://patentscope.wipo.int/search/en/detail.jsf?docId=WO2012059385
I haven't read all the 75 pages, mostly looking at the pictures :-)
But it looks like it's about combining different streams of HOA
content with mono streams to
be spatialized on the fly (sound objects).
1. Is data structures patentable?
2. If you exchange HOA with 5.1/7.1/9.1 beds it's looks a little like
Dolby Atmos, combining prerendered
surround with sound objects to be rendered on the fly
