Another question our users often ask is “how to extract voice from songs ?”, “how can i make an acapella of this song” ? etc..
Vocal isolation is a black science, it’s the voodoo of audio processing… or just a good old spectral substraction !
The principle is basic, find a part of the song without the voice, and substract it from a part with the voice, so you are left with only the voice part. The ideal situation is where you have the normal song (voice + music) and an instrumental version of the same song.
One of the most used effect in music production / sound design / FX is the DELAY.
Many VST delay plugins are available, from very expensive to absolutely free.
Wavosaur can host VST plugins, with his VST rack, and it also can load presets ! single preset FXP or presrt bank (FXB)
We have picked one of the best (and oldest) reverb plugin and made about 10 presets to show all you can do with simple delays : Blue Delay VST !! by Digilogue
You want a robot voice, a daft-punk-funky-groovy voice effect, you want it you need it.
you need a vocoder ! For quick and dirty vocoderization, you can set up Wavosaur with some cool freeware plugins and get the job done.
