<pre wrap="">Wow, very interesting collection of standards and projects.
Luckily, for the Blender integration project we just need a) a 3D
geometry file format and a b) OSC based source/listener positioning
protocol.
I don't have an opinion on a). Natanael, could you collect a list of
Blender-friendly alternatives?

OK, I'll do it. Anyway, the access and exportation of the Blender scene
objects is quite easy... so I think we can choose any format we want
based on the convenience for sound processing...<br>

<pre wrap="">For b) we need a very trivial format, since it's just a matter of
positioning sources and listener using OSC. So, starting with a (subset)
of SpatDIF i think makes sense.

I agree. <br>
BTW, thanks Xavier for your great info! I found it really interesting
(VML can be a good option for "a"), but reading further about AudioBIFS
in spite of it seems to be a really great and complete standard, I
dislike the numerous closed implementations and articles that I found.
:( Furthermore, as I understand there is some non-free licenses behind
MPEG4. Am I right?<br>
So, I think SpatDIF could be the best option. If it will not become in
a standard, it doesn't matter: using it is a way to support it, and
since it's open it could be used by anyone who wants it. And as you
wrote, we don't need so much for the moment, so if is not completely
developed right now, probably the basic proposed descriptions could be
enough (or we can improve it if is needed..).<br>
<br>
Last, but not least: talking about this with Pablo Di Liscia [1], he
sent to me an article about an interesting framework: AudioScape [2]. I
didn't tried yet, but sounds really interesting. Maybe I could
use/adapt it in someway for the proposal. For the scene description it
uses the OpenSceneGraph library, and in the paper it makes some
interesting critics to other implementations, like absence of sources
directivity [3]....<br>

on my project, but that point is essential to do it.
