Hi Markus,
Thank you for your answer - like Augustine I am also eagerly waiting the
WFS release! :)
Thank you for the links to the open music, OMPrisma etc. I was not aware
of these, and thank you for the development of the ircam tools, very
cool indeed! :)

Hi Lasse and Augustine,
I am eagerly awaiting Ircam to release their WFS software - but they haven't as
far as I know
The WFS real-time renderer is not yet released as we first have to write some
GUI objects for the filter computation tools.
The current release of the Max/Msp external library (see http://forum.ircam.fr)
includes:
- 2D/3D panning algorithms (direct panning, VBAP, etc.);
- 2D/3D-HOA (mode matching, energy preserving, max re/rv, nfc-hoa, etc.) up to
orders N = 80 (which should be fairly enough for the next few years);
- Binaural and transaural rendering;
- RIR measurement and analysis tools (exponential sweep sines, deconvolution,
room acoustic parameter estimation, etc.);
- FDN-based reverberation and an efficient low-latency multichannel convolution;
- ...
We'll hopefully soon add spherical microphone recording and processing (beam
forming, etc.) externals, which are currently under test.
Please note that Spat is NOT free and open source.
Have you published anything on how to interact with this kind of system, developed
software that makes it "easy" to make musicians improvise with the
spatialization also.. some sort of 3D environment or the likes? If not you - have you
seen any cool ways / thoughts of this?
Spat provides a perceptual control over sound spatialization, which makes it
easier for composers to interact with the system. Together with Ircam's Music
Reproduction Research Group we are working towards more advanced tools for
computer aided composition and spatial sound, such as
- OMPrisma (http://www.idmil.org/software/omprisma): Marlon Schumacher's
library for spatial sound synthesis with Open Music
(http://repmus.ircam.fr/openmusic/home);
- EFFICACE (http://repmus.ircam.fr/efficace/), a research project funded by the
French National Research Agency which aims at integrating spatial audio
rendering to Open Music.
With cheers from Paris,
Markus

Markus: I have a soundbar under my television, can your system also
make sound seem as it comes from behind me? ;) hehe.. phew, this
sounds crazy..
But my actual question.

All the best,

Dear Sursounders,
For those of you who are interested in some more details about the
IRCAM array:
The array is installed in IRCAM's variable acoustics concert hall
(15.5 x 24 x 10.5 m3). It consists of four horizontal linear arrays
(with a total of 280 independently controlled coaxial speakers) that
is complemented by a 3D rectangular array (with a total of 59
independently controlled coaxial speakers), and 8 subwoofers.
Horizontal array:
- front array: 88 speakers, 16 cm spacing;
- side arrays: 64 speakers, 29 cm spacing;
- back array: 64 speakers, 16 cm spacing;
The front and back arrays can be used as mobile arrays for concerts
(rigging structure + flight cases).
Real-time audio rendering is achieved by parallel processing on a
small computer cluster. The 5 computers are connected to a 512x512
MADI matrix for routing the output channels to the speakers. The
real-time audio processing software (ircam spat~) provides several
sound spatialization methods, e.g. WFS, (NFC)-HOA, VBAP, etc. … The
standard configuration uses WFS panning for the 4 horizontal arrays
and up to 9th order HOA for the rectangular array.
Best regards,
Markus

oh and IRCAM - IRCAM have a really good one I hear (and one day hope
to actually hear)
