Hello and welcome to this week's article!
This tutorial is to be considered as an expansion of the Autotune article, since it shares with this the same basic concepts, but the Vocoder is a little different:
Vocoder is the contraction of the two words "voice encoder", and it consists into an algorhitm that takes a sound (usually a voice) and processes it throug a synth, basically morphing it and tuning it on the note chosen by the player, with a keyboard, or writing it on a piano roll Automation (click here for an article about automations).
This effect has been widely used throughout the '70s and '80 by the first electronic music bands, such as Kraftwerk or Giorgio Moroder, and by some progressive rock band as the Alan Parsons Project, and today the effect is used to give a voice the typical metallic sound of that time.
A Vocoder can be programmed almost the same way an Autotune can be:
First we need to create an audio track, which will contain the Vocals we want to effect, then we load into this track's insert the Vst Vocoder.
At this point we'll need to create a midi track, choosing the Vocoder as output.
Now we can draw on the midi piano roll of this track the notes we want our voice to go through, or we can play them in real time with a midi keyboard.
Here are some cool Vst Vocoder downloadable for free:
Tal Vocoder - an interesting vintage sounding Vocoder
Voctopus - 8 band real time Vocoder with built in synth
Braindoc Lpc Vocoder - a Linear Predicting Coding Vocoder
Vocovee - a real time Vocoder
