Dear colleagues...
I take the opportunity to inform you about recent work at the MPEG,
presenting updates and (by documents backed) official information.

I am apologizing for the HTML -- plain text msg. formatting errors, I
never seem to learn this.
MPEG Surround was also defined as one of the MPEG-4 Audio Object
Types

Hi ...
Here some expert view on the technical background, presented by some
company in this area:

Current state of the art.
Look for example to p. 6, perceptual attributes that characterize
natural, 3D-audio.

P.S.: FLAC was the first widely used codec for lossless compression, so here
the commercial competition has a problem.
How so? FLAC has a different design objective than some of the commercial
lossless codecs.

FLAC was intended mostly for rippers, i.e. people who want to encode a lot
of CDs, and store them and play them back on computers,

Stefan, I was not stating that MPEG and ISO are evil. As a hobbyist, my
question is: how Ambisonics might be included in a standard format made
by the industry for the industry, that everybody would then have to
use if there are no viable (and simple) alternative appart

Really?! Java is not free, unless you are referring (only) to the
programming language. (Libraries? VM?)

The MPEG is part of the International Standard Organisation (ISO), in
fact it was founded by both ISO and IEC.
Ok, the citings and links weren't presented in the desired form.
I guess this is because there was no clear ISO standard for HTML
citings...(In fact, maybe this is because I was copying HTML to
plain text format, forced by the sursound list owners to do so. :-) )
Anyway, I am completely

Hi Jo,
To some extent, yes, but only if you are working with material
which can tolerate the artefacts that blind source separation
algorithms will, sooner or later - and usually sooner - generate. Such
algorithms, including those in Harpex, are getting much better (I can

Hi Stefan,
I doubt if B+ would meet the currently perceived needs of cinema
surround mixers/producers since it does not have the ability to go
discrete. B++ might be enough - that's first order + 5.1 (I just
made that up :-)).

I also fear(ed) that 5.1 + FOA (B++)
