so i upgraded to windows 7 and i had to re-download the driver to my MOTU firewire soundcard
the mixer now sports a spectrum analyzer that seems to go all the way down to 0 hz
the disturbing part is that on a lot of music the graph goes all the way to 0 hz with quite substantial amplitude i might say - about the same level as midrange signal
i used to think the peak energy in music is around 100hz with virtually nothing below 35hz but now it looks as if the peak is around 60 hz, and at around 35 hz there is a STEP to perhaps 10db lower but after going down by about 10db it just doesn't stop ...
ok so on most music it does stop at around 30 hz but on quite a sizeable portion of music it does not.
worst of all i was running sinewaves thourgh sennheiser HD555 headphones and i can clearly hear 18 hz. i am not talking about feel here i am talking about HEAR. also aside from the nausea i find the sound quite pleasing. purrrr.
and there i was thinking that i only need to get down to about 25 hz and i will be fine for music. crap.
so next time around my goal FOR MUSIC is probably going to be FLAT to 18hz and usable response down to DC.
