    Unhappy wav2mp3 conversion

    can someone guide me online to write exactly a wav2mp3 software. tell me exactly what to do about it. this is not actually for me but for a friend of mine to whom i actually suggested that. before suggesting i din know that it involved dsp. so now we r actually in a fix. learnt the format of wav file(good if it helps). dont know exactly the format for mp3 but just have a hint (mp3 format is pretty difficult to find on the net).
    now as far as we have learnt the conversion involves in the elimination of sounds from wav file which are not in the audible range.(or something like that). now we have been told many times that this actually involves dsp. as we both dont know anything about dsp we would appreciate if someone could help us out in the topic.(the lecturer in our college who is the only one who knows dsp seems to be busy so this is our last hope).
    pls help us.

    The 5-second google link - http://www.dsptutor.freeuk.com/
    The basis (as far as I know) of extracting frequency information is the Fast Fourier Transform (you can google that yourself)
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Check-out LAME.

    The reason you are having difficulty finding the mp3 file-format standard, is because it is not in the public domain. You are supposed to pay a licensing fee if you want to include it in your software.
