the only information i have regarding spatial location is a comparison made by a military radar specialist who found that his attempts at localizing weren't working nearly as well as his own ears during blind tests. i wasn't particularly impressed with his methods, but it's the only test i could fin...

Gorsnak , that'd nicely explain why post-echo is so much easier for me to detect with headphones. for me it's headphones all the way when i want to listen to something intently, whether for testing purposes, transposing a song or just because i love the music (10 years of piano + saxophone + clarin...

You are partly right anyway: on some things (as you note), instruments are much better than human ears, but on others electronics do not approach the human ear's sensitivity to nuance. Now, if you were worried about reproducing music in a way most suited to humans ' fidelity/enjoyment rather than f...

nope, it's because of masking that all psychoacoustic codecs exploit to either highly-quantize or remove frequencies altogether, if neighbouring bands contain enough power. depending on your lower bands, you can often get away with altering > 16khz data by even larger amounts. this isn't new, it's b...

although this debate is winding down, the human ear is not equal to nor more sensitive than electrical instruments. this has been conclusively proven by lossy audio compression testing, where an overwhelming majority of the population can't pick the difference between two signals that differ by 10+ ...

i'd just like to re-iterate that this fan has been working very nicely for me on an xp-90, and now that my new motherboard has pwm controls i can say the fan exhibits no additional noise when pwm or voltage controlled. not bad for a $2.50 ball-bearing fan. at low pwm levels it's effectively silent f...

those 'passive' 1u and 2u heatsinks are only passive in the sense that there's no fan attached - they still require huge amounts of air to be shifted through them to adequately cool. 1u/2u servers i've stood near created a fearful amount of noise, which was front/back fans forcing air through the ch...

the number of people sampled is low for population testing, but the people involved were presumably high-end audio enthusiasts, and none of them could tell the difference. having 7 involved people all fail to find a difference is more convincing than having no people at all ever bother to do blind t...

well, no ac -> dc conversion can be perfectly efficient, some heat is always created. it's possible to get it up to 95% efficiency or so, but that requires extremely expensive parts. if your psu is 80% efficient and you ask 150 watts from it, you'll have 37 watts of heat appearing that you have to d...

i'd just like to remind anyone using this board that a clockgen has been released for it - check the clockgen homepage for the rs480m2 build. since the onboard clock generator is a bit on the crippled side, the highest value you can choose is 220 mhz. regardless, that's a 10% faster machine for free.
