I'm getting some pretty weird results. With my cheap desktop speakers there are odd stereo-panning-like effects even though there is no panning in the audio. This could be because the speakers are awkwardly placed behind my monitors, and the monitors and other crap are in a weird asymmetrical configuration (limited desk space/crappy desk/really bad eyesight that forces me to use monitors at unconventionally close distances). Maybe that results in some weird acoustics.
On my headphones, I get less of this, but still an apparent "pan" around 1800Hz, for instance, and I have some weird, very sharp dips around 4100 Hz and 6900 Hz (which don't seem to happen with the speakers). Also, I can apparently hear from about 30 Hz up to only 14.5 KHz (where it drops off sharply and I don't hear much else other than some faint aliasing noise at times), but I feel I remember being able to hear a bit higher than that not too long ago.
Now, I did have a flu or something early November, and I had a lot of fluid in my ears for a long time, and technically I'm still not quite completely over all the effects nearly a month later (I feel pretty much fine but am still coughing some), so I figure this could be having an effect, too. Maybe I'll have to wait another month or so and see if things are any different then.
