i did, but not at low-level. usually you will have a rendering machine, and there will be any kind of interface for communication between this system and the audio software (for instance csound). i worked with the wfs software which has been developed at TU berlin (and described by marije baalman); the communication between the system and csound was done via OSC.

This is what we might have access to: http://gameoflife.nl/en/ I believe they use SC3 to run the system. So did you use Csound to control the parameters of the system?

Hi Peiman,

Yes, that system uses SuperCollider, but it's actually a patched version, it will not run properly on vanilla SC. I tried to build it once, with one of the author's help, but didn't succeed...

Most if these systems are just spatialization systems, so the audio generation is generally piped into the system from any other system (through jack for example), and the spatialization control is sent to the engine, usually using OSC.

So you just need to patch your audio sources into the system and then tell the system where to put them using their OSC namespace. The practical issue is to synchronize stuff if you are not running the spatialization from the synthesis software.

Cheers,
Andrés

Thanks Andrés,

Jack sounds promising. I'm thinking of defining a large array of virtual speakers with the wf system and then using them as if amplitude panning. So Jack should do the job nicely. Although I don't know if  it has a limit to the number of I/O channels. It would be nice to have, say, 600 channels. 

Cheers,

Heresy! :)

I think amplitude panning is a good proposition too if you have the hardware to support the outputs (you may need extra firewire busses (which is not the same as firewire ports!)). I think Jack should be able to handle 600 channels. You don't want to connect them manually though! Jack probably has a limit but it's probably much larger than 600. Then you would have to handle all the output and panning yourself. It would be interesting to see Csound driving that 600 channel system. BTW, do you know what hardware they use to handle so many channels? Here in the Allosphere we are scaling the system up to support more than 100 channels, which has meant installing extra firewire cards in the audio machine.

Cheers,
Andrés

:) But they would have to use OSC over the internet!

We're using Echo Audiofires which have 12 analog channels output each, and they go directly to powered speakers. You can daisy chain 2 on a single firewire bus, and that's what's driving the current 54.2 channel system. The main issue with setting up more channels in the Allosphere is more a matter of how to place the actual speakers (the actual sphere is not strong enough to hold speaker so they must go on the strong ribs or from other ledges), and actually getting up and mounting the speakers requires mountain climbing equipment and expertise (some locations are very inaccessible as the space between the sphere and the walls is small and the sphere itself cannot be touched as it is made of a very delicate material -perforated aluminium I think).

Cheers,
Andrés
