I'm a PhD student at the Brain Sciences Institute in Melbourne, about to embark on my first experiment looking at cross-modal attention affects on event-related brain potentials. I'm planning on using simulated "spatial" stimuli in one of my tasks. I have some flashing lights located on the left, right and center in front of a subject. There are some beeps that I'd like to play thrpough headphones AS IF they were coming from the location of the flashing lights. They don't have to be exactly localised at the location of the lights, but I would like them to be vaugely from the same area. What I'm looking for is a way of "spatialising" my (already made up) sound stimuli. I'm aware that the HRTF for each person is different, but am think that perhaps i could use a small set of typical HRTF's that would cover "large-headed", "small-headed" etc people. What I was wondering was 1) is this a good idea 2) where should i start looking for ways of actually implementing this? I have a passing familiarity with MatLab etc many thanks for any pointers in the right direction! -hamish-
