Dear Alberto,
Thank you very much for INFO about hardware for your new RTX
and we are all expecting your new software with big impatience. My
sound card is AC97 in my laptop Asus P4. I tested for the first time
my receivers on some other PC during this weekend and find that
problem with some rear appearance pulses very short duration not
exist or it is very hard to detect. Probably it is problem inside my
PC Asus A2.I apologize for maybe unregular question because this rear
effect was best visible in your software from time to time but I
really don't know why? You said that you limited audio bandwidth
inside program processing but when you synthesized audio output
spectrum is it also limited bandwidth or not? My headphone is a very
good HI-FI product and I detect easy all unwanted products?
