Effects to sound out of tune?


Would it be possible to add effects to a voice sample to make it sound out of tune in normal, conversational speech?

No smurfing, muffling or Barry Whiteing it, the aim here is to do the exact opposite of what autotune would do to a voice. If it is doable in Audacity, how would you try make that happen?

Until just now, I didn’t know what this program was about and I have zero exp in music. If you come up with an idea, please give it as noob-friendly you can :slight_smile:

Using OS X Yosemite 10.10.1 and Audacity 2.1.1 (ZIP, 16.50 MB).


There’s a “Random Pitch Modulation” plugin for Audacity.

It’s not the “exact opposite” of autotune, (which would exaggerate any existing out-of-tune-ness), but just randomly detuned.

Thanks a bundle!

If there are other ways to de-tune vocals, please let me know :slight_smile:

There’s vibrato, where the pitch-variation is cyclical rather than random.

Try this in the Nyquist Prompt effect:

;version 4

;control speed "Variation speed" float "" 5 0 10
;control strength "Variation amount" float "" 5 0 10

(let ((noise (mult strength (snd-abs (lowpass8   (noise) (/ speed 4.0))))))
  (multichan-expand #'tapv *track* 0 noise (/ strength 10)))
