fft calculation via mpeg encoding

    ripped this form a pdf on a dancing-robot-to-the-beat project. http://www.8-legs.org/ewilhelm/projects/2.165/dance%20report .pdf
    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
