hi all, and thanx fr looking at this post.. ;-)
so, you know when there's, for
example, a bad guy on the telly and his voice is all slowed down and grainy sounding to
protect his identity (couldn't spell anonymity !!)... how would one go about achieving
this effect ?
Any ideas ?

Pitch shifting the audio whilst retaining the timing is one way. You could also send the
vocal to a pitch shifter effect. The granulated sound can be achieved using a bit crusher
or other sample rate reducer.

Remember however (if hiding the original voice is important) that if the voice's audio is
very clean and isolated from other sound material, it will be quite easy to pitch shift
it up back to its original frequency and thus eventually recognize the speaker. Some (not
tested) ideas:
- One way you can avoid this should be to complicate the edting
process a bit, like using serveral effects on the voice to make it harder to be
reversible.
- Another solution could be to mix the spoken voice with other audio
(like some strong background noise or some music), that should help to complicate the
reverse process in order to have the original voice clean and clear.
Anyway
the best is always to do the "reverse tests" in the end and check if it's too easy to get
back to the original audio.
Good luck! :-)

Hi
I don’t know if your intention is to change your own voice,or try to recover a
normal one from a treated voice,but,if your intention is to change yours(in a way that’s
difficult to retrieve),I would change it’s frequencies and characteristics first…Like
using some heavy EQ filtering(and then apply effects)…That way,even if someone manage to
go around the effects(pitch shifting,harmonizer,etc),he will face a voice that’s very
different from yours in the first place...
