Fruity Vocoder

Fruity Vocoder is an advanced real-time vocoder effect with a wide range of adjustable parameters and zero latency. Vocoding is the process of using the frequency spectrum of one sound to modulate the same in another. The vocoder acts like a series of gates allowing through those frequencies it detects in the modulator. When a human voice is used to modulate a synthesized chord, for example, it can sound like the synthesizer is talking (a classic robot voice from sci-fi).

The vocoded sound is referred to as a carrier. The sound used for vocoding is called a modulator. A classical example is having a voice as a modulator and a synth as a carrier, to create the effect of a 'speaking synth'.

The vocoder works by detecting the levels of certain frequency bands and then filtering the carrier. Thus the carrier takes on the characteristics of the modulator sound.

  1. Load: an instance of Fruity Vocoder in a mixer track effect slot (don't use the master).
  2. Routing: By default, the left channel is the modulator and the right channel is the carrier. This means the vocoder can only process a mono input sound, although the output is stereo. The modulator/carrier channel assignment can be swapped from the MIX section. There are several ways to create a modulator/carrier combination in the L/R channels of a Mixer Track:
  3. Carrier sound - The most effective carriers (the sound you hear vocoded) are those covering the whole frequency range. Pad sounds often make good carriers, you can also try mixing in some white noise if you need to hear speech (s & t sounds) vocoded more clearly. Remember, the vocoder acts like a series of gates allowing through those frequencies it detects in the modulator. If a frequency gate opens and there is no carrier sound in that band, that part of the 'tonal' character in the vocoded sound will be lost when compared to the original.
  4. Modulator sound - Using some compression on the modulator usually helps sound (and speech in particular) to vocode more clearly.


FREQ section

ENV Section

Sets the envelope follower attack and decay. This is the fade in/out times for the envelopes of the frequency bands tracked in the modulator sound.

MIX Section

Mix the source and carrier levels using the sliders. To solo the left (modulator) or right (carrier) channel click the LCD switches.

To swap the left and right channel assignments and change the channel the modulator and carrier are taken from, click the L and R labels at the top.

Bands Display

Displays the bands and their volume levels and the sound plays. You can adjust the volume of the individual bands by dragging up/down the sliders in the view.
