This is my attempt to make a vocoder within Audiotool. This was a pretty hard task, since I only had the devices within Audiotool to work with, which are more suited for music, rather than this kind of signal processing, so with a little imagination, this maybe sounds like an older kind ov vocoder, that is not that linear and provides some vintage distortion. ;) But I made an attempt, and this is the result.

How it works:

A vocoder makes it possible for a voice's pitch to be controlled by an other signal's pitch, without changing the voice's character (more or less). Therefore, a vocoder has two inputs, one for the voice, which is called the modulator, and one for the adjustable frequency(/frequencies), which is called the carrier. In this case, the modulator is provided by an Audiotrack and the carrier is provided by a Pulverisateur. What the modulator do is splitting up its signal to a couple of bandpass filters set to different frequencies. The number of filters the signal is splitted up to is the number of bands of the vocoder. Each of the signals that comes out of those filters then controls the output signal of an other set of similar filters. These signals are then merged together and being sent to the output of the vocoder (which is being provided by the output of the Kobolt mixer). The result of this is one single audio signal, with the frequency(/frequencies) of the carrier and the sound characteristics of the modulator. It is consequently possible to make a sound of an existing voice with a custom frequency(/frequencies).

Tips:

*Change the notetrack of the Pulverisateur and see what happens.

*Change the waveform of the Osc 1 of the Pulverisateur and see what happens.

*Change the content of the Audiotrack to another wavefile (not necessarily a recording of a voice ;) ) and see what happens.

*Replace the Pulverisateur with something else (preferably something that produces a sound) and see what happens.

*Add effect chains after the Carrier or the Modulator (or both) and see what happens.

Have fun! :)

  • Are you trying to light my computer on fire, holygosh

  • This is one of the most innovative, creative, and effective Templates I've ever seen on AT. I'll definitely try to incorporate it into one of my future tracks! :)

  • Ohoho! I'll surely check this out!

  • And thanks! :)

  • Whoops! I meant "it's not your fault" in my second oldest comment and autocorrect happened to change in to I'm. I sat on the train and I was in a kind of a hurry, so I didn't really have time to read it through one last time before pressing 'Comment'. Sorry for confusing you! XD

  • Woaah such complex connections ;) This sounds amazing... And it works ! :D

  • ...

    That signal is the one that we hear, and we hear it like, in the case of this unchanged template, a "talking" sawtooth wave.

  • ...I need to check this, love such experiments

  • Thanks very much folks! :)

    I just discovered that I missed out a major part I'm the description, so if you feel like an idiot when reading it, it's not my fault. ;)

    The thing I missed out is where the other set of filters get their input signal from, which is the carrier (the Pulveriasteur), which results in that the output signal from the carrier get the frequency spectrum over time by the modulator (the Audiotrack).

  • This is perfect!

  • Hey What's up, this seems like a very hard way to make vocorder sounds, I come close to the sounds just using the H and P and some Fx pedals...

  • Thank you guys! :)

    @Inavon : Hehe, I wouldn't really say that I'm hacking it; it's not like taking advantage of glitches or something. I would rather say that I'm trying some unexpected things that Audiotool isn't really meant for. ;)

  • amazing stuff ! thx for sharing !

  • very cool idea!

  • Good stuff! Frigolito always hacking Audiotool :)
