hi mandy,
first of all, you live in bristol? i love it there! i went by
myself from london just to see a band that i'm in love with. i got a bit of a chance to explore the multimedia stuff, but for the most part i was record shopping. i didn't get to the bridge though; i really wanted to see that.
anyway, i'm working on implementing HRTF convolution in Pd. i'm
not a VERY experienced programmer but i have some skills, and i have a lot of people in the spatial audio field helping me out. i actually wrote my own convolution patch but it was brute-force, and in the end it took too many CPU cycles. it just plain old didn't work, so now i'm using FFTs to do it and hopefully the CPU can handle multiple sources. how many HRTFs do you have? i'd like to eventually modify the external so that it would be very easy for anybody to use with however many HRTFs with however many taps.

Hi people,
I suppose I'm a complete newbie and therefore inevitably will ask dull and repeated question.. but.. I am looking to produce as near as effective 3D sound in real time on a PC (windows I'm afraid). At the minute I am using a sdk which sits on top of the DirectSound API which sounds pretty good (to me anyway) but has anything to do with HRTFs been implemented in pd? I've heard of spat~ but I am presuming that this is a.)max related b.)relies on external DSPs and c.)not free.
If nothing else newbies like me must at least create a little amusement.... thanks Mandy
