Vocoder
Program that imposes vocal effects on a waveform
Project status: still useful, but is no longer under development.
Developed: 1996-2002
This program is a free software channel vocoder, which imposes vocal effects on a waveform. It can be used to make your voice sound "robot-like", to create a singing synthesizer, to disguise your voice, and many other fun things. This effect was made popular by artists such as Kraftwerk and Laurie Anderson, and Daft Punk (using other hardware/software). This particular software works on pre-recorded files, rather than being a live effect.
I originally created this software after doing a research paper about vocoders for a course I took in my first year of University. At the time there were not many options for easy software vocoding, although since then many good ones, such as VST plugins, have become available.
Examples
Here are some examples of the vocoder output and unput files in Microsoft WAVe format.
- example1.wav - vocoded using periodic white noise as a carrier<
- example2.wav - vocoded using white noise as a carrier
- example3.wav - vocoded using synthesized strings as a carrier
Here are the modulator and carrier files I used to create them:
- modulator22.wav - my voice modulator
- carrier22.wav - synthesized strings carrier
- white512.wav - periodic white noise carrier
- white.wav - white noise carrier
Download
The vocoder is available as C source code or as a compiled binary for certain platforms. The source code should compile just about anywhere.
