    Hey guys - just hoping somebody can shed some light on this for me:

    When running any "pro" recordings i have on my computer through a freq. analyzer, i notice that there's a sharp drop of ~70dB above ~15K. I've always wondered what caused this. Is it a result of MP3/WMP encoding? Noise/hiss-reduction? Some other processing done post-mix?

    Sounds like mp3 encoding to me. Since this data adds the least to recordings, it's the first to go.

    mp3 decoding does exactly that. Removes the very high and the very low frequencys.

    running anything other than straight aiff cd rip or better will not give accurate results. run some cd rips through it, their dropoffs wont be that bad.
