    Hi, i want to create a program that reads a .wav file and performs a FT.
    In steps, the program needs to:
    1)Read a .wav file
    2)Find which frequencies the sound contains
    3)Find the amplitude and phase of these frequencies
    4)Display the data
    Questions:
    1)How can i read a .wav file?
    2)If i read a .wav file, how can i extract the frequencies it contains?Are they stored values in the .wav's data?Same about phase.
    I'm pretty lost with this project so any help will be valuable...
    Thnx in advance.
