fft calculation via mpeg encoding

    ripped this form a pdf on a dancing-robot-to-the-beat project.
    can this information be of any use in max/jitter ?
    using a prerecorded MPEG compressed audio source removed both the A/D conversion step and the FFT calculation because the MPEG format actually stores the audio data in a combination of frequency space and time space, so the FFT is pre-calculated.
    the a/d part isn't relevent
