using spectral analysis from one track to filter another

    Nov 06 2012 | 5:25 am
    Hi all,
    I'm interested in taking the spectral analysis generated from one piece of music and running another piece of music through it. As spectral analysis deals with sine wave components at all of the frequencies, shouldn't it be possible to use a sound file and its existing frequency components in the same way? Essentially I'm looking to filter one track through another's spectrum.
    Sorry if this is hard to understand, it's kind of a hard thing to describe... Any help is appreciated greatly!
    Cheers, Jay
