The system used directional sound sources and microphones and a ray-tracing-like algorithm to trace the sound. Sound sources were digitized and stored in files. Emitters used these sound files. At the end of the 4 month project they could digitize something, like a person speaking, run it through the system, then pump the results through a speaker. An acoustic environment was built (just like you build a model for graphics). You could get effects like echoes and such. Unfortunately this was never published. I am trying to convince them to work on it next semester... David Jevans, U of Calgary Computer Science, Calgary AB T2N 1N4 Canada uucp: ...{ubc-cs,utai,alberta}!calgary!jevans
