Introduction to Vocoders - DJ Audio Effects Synth Instruments

By Luis Boyd

Vocoders could actually be useful and don't necessarily have to sound like a robot. 2 in puts are needed if you are using this. One being a carrier wave, which is the sound you're going to vocode through and the second a modular voice, which would in all probability be yours. This gives a synthesiser sound thats easily recognised and in fact has been utilized since the 1960s in music.

Vocoders have a different number of bands, and the reason being is cause the modulator takes on your voice, dissects the primary 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 requires more bands. Ultimately as these filter signals are carried onto the carrier wave the final sound is emulated.

To reach the classical robot effect you require the modulator to be speech, but you can utilise anything you want as the carrier and the modulator to get other sounds. For instance, if you needed you could run instruments or other synthesizers through the modular in-put. Amusing results are what you'll get. Commonly the carrier would be a pleasantly massive synthesizer sound, like a string sound or still a long saw wave pad. You could utilise anything that had a few good depth and length to it though.

Hardware and software synthesizers that're computer now possess vocoders as standard features. Basically you just get your monies worth, when it comes to producing the sound of a dedicated analog vocoder. For example for around one thousand dollars you may be able to pick up a Roland VP-300 that is in really great shape, but then the old Korg VC-10 could be had much less costly and finer as well. Then don't leave out the MicroKorg after all it does have a microphone and its handily small and affordable 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. - 18423
