I want to distort someone's voice on purpose for a new investigative piece I am doing. What would be the best filter/tool for that in FCP?

Thanks

    I'm guessing when you say "distort" - you don't actually want to over modulate, just give some sort of stylized filter to make an old timey feel - or radio sound.

    If you mess with the High Pass Filter, you can get some good results. Set the frequency to around 1400, and the Q to about 3.

    See if that's close to what you are looking for.

    Best,

    PJ,

    Thanks for your post. Actually, I mean distort as in altering the quality of someone's voice as not to be recognizable for an investigative piece.

    Okay got it. Keep the identity a secret.

    In looking through my FCP audio filters, nothing there jumps out.



    Here is one suggestion - you can try running the audio in Garage Band and use the Vocal Transformer filter.

    That filter may also be in Soundtrack (I don't use it) - in which case, you could promote that section of audio to Soundtrack - put the transformer filter on it - and it will be in your FCP timeline.

    If you do it in Garage Band, it will require an export and then reimport (and eye match it - OR don't give it handles and overwrite it)

    Best,

    You can get good results shifting the harmonics of the voice
    with a spectral shifter. It maintains the intelligibility
    but messes with the identity. One really nice freeware
    for this sort of thing is Soundhack:

    In the Hack menu, try Convolution, Mutation, or Phase Vocoder.

    Thanks for both posts. I did not find anything in Soundtrack, but Vocal Transformer in Garageband does have a setting that would do the trick. Will check out Soundhack.
