The Raspberry PI is really cheap and runs Linux, so it does provide some real possibilities, though it is, in some ways, quite limited - max 256m ram at present, for instance - and documentation is currently not really in a "this is how you do it" state (http://www.element14.com/community/docs/

The snd_bcm2835 driver is for the integrated stereo sound module. For more channels, a cheap 8 channels USB sound module would probably work, and ALSA drivers for many sound modules are stable. Martin Leese a écrit : > Dave Malham wrote: > > > The Raspberry PI is really cheap and runs Linux,

I probably should add this: http://smyth-research.com/ They could update their system to 3D audio. TU-1 head tracker Included with Realiser; also available separately for dual users, replacement, etc. (A single set-top unit is sufficient for dual users.) $175 Could be cheaper for a CE

Lest I sound too would-be definitive, I should add that in actuality there are now concert halls with noise levels at the threshold of human hearing, at least when they are empty. Since an orchestra at close range can reach 100dB and then some(though out in the hall the level is much lower), this
