All about it since & 1989 to summer 1994. If you can read french, I got here my report that give & you a nice snap-shot (30 p) including all the references. & & & Do you have any tricks that make perception better? I thinking of & & things that I could implement besides the HRTF filters that would & & make front-back localisation better? & & 1- Besides HRTF, the most important factor is MOUVEMENT. It got to & move, because you're not just friendly (and the HRTF is not perfectly & custumized to you) with this synthetic environment. & Adding mouvement to HRTF in the way that you need it to localize the & fixed source, is a hell of programming. At this point, you need real-time & computing environment with a head-localization loop feeding your program. & The program will adjust the azimut and elevation of the source according to & the next position of your head. Wightman, F.L., Kisler, D. were talking & about that at the 127th meeting of Acoustical Society of America on june & 6-10th 1994. And I strongly beleive in that, I really do. & I've done it in a simple way. In simulation, I've just played in a & sequence, many processed sound files that are just beside one to each other. & It was just for that, much better than in a random way. & & 2- Beside HRTF again, you GOT to simulate a real environment because & you're not just familiar within an anechoic room (infinite room). Just go & into an anechoic room, and you'll be lost for a moment. You won't react the & same way to any quind of sound coming to you; your head is gonna move toward & it, I'm telling you. & So reverberation is also important, and that gives you nice sound & files with many images ( high reflexion order ) & & & I could talk to you about ... but I just can't type all about it! & For now, I am working on something else (Echo Canceller) but I hope, & I'll have the chance to work on that again. See, this tends toward & psycho-acoustic research. I love it but for now, I got to learn more about & adaptive signal processing... ;-) & & & & & Regards, & & Bo -- Francois Caron //// //// //// caron(at) INRS-telecommunications //// //// //// (at) (514)-761-8603 16 Place du Commerce //// //// //// (at) (514)-362-9015 Ile des Soeurs, Montreal //// (at) (514)-761-8501 Fax CANADA H3E 1H6
