31.0. "Soundcards and DELPHI???" by 51342::ULFH () Mon May 12 1997 17:16

    I am looking for information on how to access / program sound cards. I
    want to be able to grab information from the soundcard (sound from my
    amateur radion via the line input), analyze the sound, limit the
    spectrum to 100-3000 Hz, break this into segments of 50-100 Hz and
    find the maximum value of each segment. This must be done pretty fast!
    
    I have access to Delphi version 2.0 (should I upgrade???)
    
    Any one out there with a bright idea???
    
    Cheers

    Don't upgrade for that reason.
    
    This might help

    TEnhWave 1.03
    
        Delphi components that handle audio playing and recording. Easy to
        use. Get full advantage of buffering and queuing with no effort.
        All the dirty work is done by these two components.
    
    Fast Fourier Transformation Component 1.0
    
        A Delphi 2.0 component that can perform a fast Fourier
        transformation and its inverse. It can be well used in signal
        processing (e.g. noise reduction, frequency filtering, voice/signal
        recognition). Full documentation and sample included.
    
    Note : The www.windows95.com start page is pretty stable and unlikely
           to move, the contents however are subject to continual updates.
