    How to distort a wav file to sound like Air Traffic


    Can anyone suggest a way within CoolEdit 2000 to apply a distortion to a wav file to introduce the kind of distortion that you hear over the air please? http://freesound.iua.upf.edu/samplesViewSingle.php?id=11723 has the sort of sound distortion I'm looking to reproduce.

    Thanks if anyone can suggest a way - if not with CoolEdit then maybe suggest another program plse.

    never used cool edit, but most audio editors allow you to generate white noise (containing all frequencies). You could mix that white noise (maybe equalised, as you like) with the voice sound. Also try eq'ing the voice removing top and bottom frequencies (kind of telephone sound).

    Thanks for the suggestion - I'll have to poke about and try to figure out how to do that. - Cheers

    try applying a harsh passband filter before distorting. Or, after and before distorting.

    in => bandpass filter => distort => bandpass filter

    A technique I've used in the past is to amplitude modulate the spoken wave file with noise and then dynamically mix it with the original. To add a little realism and interest, try running the noise through a filter with a sweeping frequency (but not too much resonance). Test different types of filters (BP, LP, HP) for different results.

    Or do it the easy way... if u can't handle the filters....
    talk into a plastic cup and hold your mic next to it and hit record.....
    Try different cups and mic position... wink
    and add noise by turning on a AM radio and tune it to a 'wrong' channel...

    (ofcource this is useless if you want to apply it to a existing audiofile...)
