Hello thanks for all your answers. I had a look at some references in this field. Mostly in R. Nicoll Monograph on Binaural Technology, which is the best recent overview i could find (on AES). All the solutions mentionned in the ones you submitted are included ;) You might do better with interpola

2010-06-03 Thread arthur de conihout
Hello everybody i m fighting with a dynamic binaural synthesis(can give more hints on it if necessary). i would like to modify the sound playing according to listener's head position. I got special filters(binaural ones) per head position that i convolve in real time with a monophonic sound.When

y understanding maybe your initialisation tests will allow me to make difference between every wav formats? i want to be able to encode every formats (16bit unsigned, 32bits)what precautions do i have to respect in the filtering?do filter and original must be the same or? Thank you AdeC 2010/5/
