Vocodertreated
Vocodertreated is a term used to describe audio that has been processed using a vocoder. A vocoder, short for voice encoder, is an electronic musical instrument that alters the sound of a voice or other audio source. It works by analyzing the spectral characteristics of an input signal (often a voice) and then using those characteristics to modulate another signal, typically a synthesizer. The result is a robotic or synthesized vocal effect, or the ability to "sing" with the voice of another instrument.
The vocoder effect can be heard in a wide range of musical genres, from early electronic music
