I would strongly suggest considering a 2nd-order ambisonic setup, especially if you have Matlab. Derby University in the uk have a programme: 'simulink' which runs under matlab and which allows configuration of ambisonic decoders on fast PC with multichannel soundcards. The benefit of this route is that ambisoncs supports periphonic (with-height) displays, but it is a kernel system and so is compatible with lower-orders of spatial encoding, so horizontal-only material is entirely compatible with it. It's very easy to put mono, stereo, 5.1, 7.1 , 1st-order ambisonics, and even binaural (though here the conversion is not perfect) into an ambisonic 2nd-orderdisplay, and this can be encoded in realtime with managable latency. I know they are at present experimenting with a new 32xspeaker periphonic setup for medium-to-large scale listening, running on a PC with 2x16ch soundcards (operated as a single device). I can find out the soundcard manufacturer if you wish regards, ppl ----- Original Message ----- From: "Sanja Dupor" <106744.1511(at)COMPUSERVE.COM> To: <AUDITORY(at)LISTS.MCGILL.CA> Sent: 24 October 2001 08:16 Subject: Multichannel audio cards Hi Regis, see EWS88MT Terratec card at Zlatan Nachricht geschrieben von Regis Rossi Alves Faria > We are looking for suggestions on multichannel audio cards (models and/or brands) as well as multichannel softwares (to generate more than 2 stereo audio outputs, be it either 5.1 or n-independent channels/outputs) to drive a virtual 3D (audio) environment (i.e., n independent speakers set in a way to produce audio spacialization). The system is to synchronize with a similar virtual 3D visual environment, where objects can be visualized and heard. Those who can advise on this, or think could help if having more information, I would be grateful in contacting. Regis Rossi A.
