Try it with headphones. If you crank up the gain, then you'll hear it better through speakers.
We discussed this kind of effect over at linux audio user, and it seems that this effect is a very specialized effect, only applicable at the listeners end. This is not to discourage you, just to pass on advise from a person who's knowledge I respect (Fons Adriaensen). That said I'm gonna check your code out for sure, it sounds interesting!!! Me: "So the delay part is crucial and the result can be good? I don't understand how long the delay should be (although I know how fast sound travels and how far apart my ears are). Supposed I'm 10 meters away from a PA (speakers 10 meters apart), what should the delay be? What if I'm listening at home, 3 meters away from my home stereo (speakers 3 meters apart)?" Fons Adriaensen: "It's not supposed to work in those conditions. What you need is two speakers that you see in an angle of about 20 degrees (so much closer than normal), and a distance of around 2 to 3 meters. The 'sweet spot' is quite small. Two or more listeners should be behind each other, not besides. The required delay is very small, around 100 us." Me: "What if I'm listening through headphones?" Fons Adriaensen: "Bad idea ! Xtalk cancellation is used to *replace* headphones, while allowing the listener to turn his/her head w.r.t. the speakers. Allowing this makes the image much more 'real' than with headphones."
Thanx to the person who helped me with the inversion (sorry I forget your name, but you know who you are <smile>).
That would be me :-) -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
