If you can't hear the low stuff, it may be your speakers/monitors/headphones and not you. I could "hear" the 20hz with headphones, but it was more rumble than sound. I could hear 17k, and was vaguely aware that something was going on for 18 and 19, but by 20, I may as well have been sitting in silence.
GratifyingI thought I was much worse off than that after standing next to the crash cymbal for as long as I did.
wow! - that middle picture is awful -- but I bet I could hear itYou also can see in the waveforms the poor frequency response of the card
Interestingly I used a reasonable wave recorder to record it as I went so I could look at the results (without joining) & NOTHING except the "on" click & voice recorded after 18khz.
Very cool test for not only checking your hearing range but the frequency response of your different monitoring systems.
I wanna get my dog in here and turn up the 22Khz and see what happens
