    So I create a frequency sweep in Adobe Audition 3.0.
    5-22kHz for testing gear..
    Whenever I do an offline frequency analysis of the sweep, how come the lowend up to 160Hz
    is rolled off very slightly...
    Even when using a spectrum analysis plugin, set to averaging, to maintain the trace.
    Then loop and play the sweep, to create the trace. I still see the slight rolloff in the lowend.
    Since all frequencies are supposed to be equal volume in the sweep, why are some showing up at a lower level in the lowend?
    Changes depending on if I select Log or Linear sweep...

    You may have to change your meter/generator settings to unweighted.
