Monster Voice Changer
This one changes your voice so it sounds sort of like a big evil troll/monster. Behind the scenes I've done some fancy stuff with oscillating signals such that it's deeper and slightly distorted (like the monster's voice box is a bit damaged or something), and then I've cleard out the high frequency parts of the signal to smooth it off.

PA Speaker Voice Changer
This one is meant to sound like a booming PA (public announcement) speaker that's very bad quality. I imagined it was from some sort of distopian authoritarian government telling its citizens what to do, but I think you could just as easily use it as if it was a PA speaker from the 50s or something. It first distorts your voice a bit and makes the signal noisy and then adds an echo effect.

Reverse Reverb Voice Changer

Anonymous Voice Changer
We've all heard the anonymising voice effect before, and this one is similar, except it adds a slight distortion to your voice to make it more on the "hacker" side of things. Note that this shouldn't be used for real anonymising! It's just for fun.

Cymbal Voice Effect
This is a strange one. It uses "impulse response convolution" to create an "echo" of your voice that sounds a bit like a cymbal in a drum kit.

Dalek Voice Changer
This uses a "ring modulator" to simulate the same electronics that were used to generate the Dalek's voice in Doctor Who. You should do try to make your voice sound like the Dalek's when you record the audio, and this effect will do the rest.

Demon Voice Changer
With this effect I tried to create the sense that it was an epic demon beast thing. Much like the Balrog from Lord of the Rings. It adds some fire crackling effects in the background, deepens your voice, and adds an ominous echo.

Sauron Voice Changer
I've tried to make this effect sound like Sauron's voice (from Lord of the Rings). He doesn't talk much in the movies, but when he does it's very deep and has a slight ominous echo.
Russian Voice Effect
This is a silly effect that chops up the audio clip into segments, reverses them, and then puts them all back together. It sounds a little like some eastern European languages.
