Re: [sc-users] general Binaural question & specific Ambien question

[Sciss <contact@xxxxxxxx>]

i have used HRTF impulse responses from the IRCAM listen project  
( http://recherche.ircam.fr/equipes/salles/listen/download.html )  
with Convolution2 a while ago. It works very nicely, after you have  
truncated the IRs to the minimum required length (= minimum CPU  
load). Don't ask me though how many convolutions you can get on one  
machine. There's a menu item Extras -> HRIR preparation in meloncillo  
( sourceforge.net/projects/meloncillo ) that does the impluse  
response truncation for you. the LISTEN database is only sampled for  
some angles though - on the other hand you can choose the file that  
is the most realistic for your head -, and you might need to simulate  
spatial depth (distance) maybe....

ciao, -sciss-
