[Openal] 7-speaker sound with Mac for auditory research?

[William Stewart]

We are planning on supporting up to 8 channel configurations (inc.  
7.0 (we don't output separate info for the LFE channel) as well as  
octagonal speaker systems) for Leopard.

If you would like to test this (which would be great!), you can enrol  
in the Leopard seeing program (I'm not sure of the exact process, but  
http://developer.apple.com should have details). That will get you  
early access and the ability to test this before we ship (though it  
is late in the game for Leopard at this stage).

Thanks

Bill
