A Beginners Guide to Vocoders and VST Plugins

Vocoders can actually be useful and do not necessarily have to sound like a robot. If youre going to use this, you'll need 2 in-puts. One being a carrier wave, which is the sound you are going to vocode through and the 2 a modular voice, which will probably be yours. This provides a synthesiser sound that's easily recognised and in all sense has been utilized since the 1960s in known music.

Vocoders have a different number of bands, and the reason being is cause the modulator takes on your voice, dissects the essential parts which're the fundamental frequencies. Then these're changed into levels of amplitudes on a group of band pass filters. To make your voice more audible it needs more bands. Ultimately as these filter signals are carried onto the carrier wave the last sound is emulated.

To reach the basic robot effect you require the modulator to be speech, but you could use anything you need as the carrier and the modulator to get other different sounds. For illustration, if you wanted you could run instruments or some other synthesizers through the modular in-put. You're certain to obtain numerous interesting results. Commonly the carrier would be a agreeably massive synthesizer sound, like a string sound or still a long saw wave pad. You can utilise any thing that had some good depth and length to it though.

Hardware and software synthesizers that are computer at present possess vocoders as general features. Basically you only get your monies worth, when it comes to getting the sound of a dedicated analog vocoder. For instance for around 1000 dollars you might be able to pick up a Roland VP-300 that's in truly good shape, but then the old Korg VC-10 could be had much less pricy and better too. Then do not leave out the MicroKorg afterall it does have a microphone and it is handily small and affordable all at the same time.

Dont rule out the talk boxes for obtaining those robot voice simulations, as they dont all come from the vocoder.Then theres that increasingly popular auto tune software or speech synthesis.
