How to make a voice/person unrecognizeable?
I need to play voice recordings so one can understand everything
including how it was said, but one should not be able to recognize the voice (person). What is the best way to do that - staring with an digital recording, using Amadeus II on a Mac? or which filters etc would do that? TIA Marc -- Marc Heusser (remove the obvious: CHEERS and MERICAL...until end to reply via email) |

What I've always heard on TV sounds like going through a balanced modulator/single sideband modulation to add and/or subtract a constant to the frequencies, but if I were the one doing the talking, I'd worry that this (or other processing) could be undone and my voice be made recognizable. Even one's speaking habits such as uh's, ah's and pauses will come through, which may be unique and recognizable. The best way around this is to do a transcript, record someone else reading it, then process THAT voice (misleading listeners to think it's the original voice). Be sure to reword any unusual or unique word combinations. What is the best way to do that - staring with an digital recording, using Amadeus II on a Mac? or which filters etc would do that? A vocoder would flat-out remove the original pitch information (hmm, so would Autotune), which may help. Another disguising technique is low-cut EQ, then hard clipping, then high cut. Do you have a guitar amp simulator? TIA Marc ----- http://mindspring.com/~benbradley |

You want a vocoder. mda Vocoder is already on your machine, probably (esp if you have Amadeus). Zerius provides more interesting possibilities, though! Hum into your computer to provide a "carrier", run the voice through it ("modulator"), and it is very, very disguised. m. -- matt neuburg, phd = , http://www.tidbits.com/matt/ AppleScript: The Definitive Guide http://www.amazon.com/exec/obidos/AS...methingsbymatt Read TidBITS!

You can easily turn a woman voice into a man's voice and vice-versa, which would make it quite unrecognisable. Just use the "Change Pitch and speed" function to decrease (resp. increase) the pitch by about half an octave (that's 3 tones). HTH Martin |

Want to really change a voice try Antares Kantos! Voices have never been
changed more drastically than by this piece of software. Max Arwood "Marc Heusser" alid wrote in message ...

Boss used to make a fairly inexpensive one, probably still do. Hardware beats software for this sort of thing. -- I'm really Mike Rivers ) However, until the spam goes away or Hell freezes over, lots of IP addresses are blocked from this system. If you e-mail me and it bounces, use your secret decoder ring and reach me he double-m-eleven-double-zero at yahoo I have that little Orange Boss voice manipulator. It's actually pretty cool. It would work well in this application. -- -- John Noll Retromedia Sound Studios Red Bank, NJ http://www.retromedia.net |

What's the budget of the person you're trying to fool? If you're talking about the needs of a theatre production, you want a "flavor" rather than true obfuscation. In the original "Little Shop of Horrors" cast, "A Voice, Not Unlike God" played about six different roles, including some drag. His voice was "disguised" but he wasn't fooling anyone who really listened. If you're doing a practical joke (or committing a crime) it has to obfuscate within the fairly narrow bandwidth of a telecom channel (4kHz). Finally, if you're trying to fool the people who in the US are called "Three-letter agencies" I suggest you find an easier line of work. |
