    Hi all,

    I am currently researching on a research idea I have. I need help in one of the tasks for the research which is stated as under.

    Problem description:
    1. Given a music track, list all the frequencies in the track.
    2. Normalize this output to have a specific range of drop and rise of frequencies.
    For eg: If we got that the frequencies are 500,501, 499, 555, 590, 100, 102, 101
    It should be normalize to 500, 555, 590, 100

    Trials as of now:
    1. Audacity: I tried audacity but all i get is a graph of the frequencies on the graph and no details about the frequencies.

    I am not able to figure out. If some one can help me in this, would be great.

    Frequencies don't show up as "there" and "not there". What they do is, show up as various amounts, kind of like shades of gray in a photograph. What you seem to require is the raw sample data which you can then process via FFT to extract the frequency domain information.
