My tinnitus was described as sort of a "phantom limb" effect resulting
from my high frequency hearing loss (I can't hear the upper half
octave on a piano). In any event, a pair of digital, very expensive
hearing aids makes a world of difference. I rediscovered that paper
crinkles, water splashes, and coins jingle, things I hadn't heard in
ages. And my tinnitus is either gone or I just don't bother to care
when my hearing aids or on.
Even your cheap computer audio system should be good up to 8 or 10
kHz. So if your high frequency cutoff is 5 hKz it should be fine.
There are a number of fourier transform (FFT) programs. SigView
http://www.sigview.com/ is relatively inexpensive. Google, of course,
has a good list at
Reliable software has a little unit on FFT
and a free frequency analyzer at
http://www.relisoft.com/freeware/index.htm. Source code is
also available to help you roll your own.
I used to have software to do all that but it was years ago.
