Audio examples



Vocoders rely on two signals being present at the same time in order to operate. These signals are the Carrier signal, which normally takes the form of a synth, and the Modulator signal, which normally takes the form of a human voice, although other instruments can work well (such as drums).

The Modulator signal is analysed by the vocoder and broken down into a number of frequency bands. The more bands that are available, the better quality of the analysis, which means that a clearer vocoded sound will be available. A typical Vocoder synthesizes a modulator (usually a voice) in the right channel of a stereo track with a carrier wave in the left channel (any active sound) to produce a vocoded version of the modulator (right channel).

What makes the ReVoicer different from a typical Vocoder? It is a Stereo Spectrum filter-bank Vocoder with an Internal Oscillator that can work as Oscillator Instrument, or Internal Carrier to synthesise vocoder sound.
The External Carrier stereo inputs can be used, or use/mix the Internal oscillator (which includes basic waveforms such as Pulse, Saw, Tri, Sub and Noise), to vocode the Modulator inputs. The Internal Oscillator can also be used as a simple Oscillator (it can be processed by the Vocoder) and as part of a vocoder (internal carrier) for fast results without the need to create any external Carrier device in Reason’s rack.
ReVoicer is a modern stereo Vocoder with internal oscillator, limiter and spectrum frequency control. It allows for a lot of vocoder variations in order to create unique Vocoder textures for any vocal or instrument sound.

ReVoicer comes with a variety of patches including 70+ Combi vocoder FX patches.

Product details

The Voice Operation Demonstrator (Voder) was developed by Homer Dudley at Bell Labs in the 1930’s as a device capable of imitating human speech electronically. The first commercial use of a Vocoder in music was in 1968. Bruce Haack built his own vocoder that was used on the album The Electronic Record For Children. At the same time, Bob Moog developed his own Vocoder. Kraftwerk brought the instrument to mainstream when they used it on their album Autobahn in 1974. The Soulsonic Force used a Vocoder in their hit Planet Rock as early hip-hop artists in 1982. Modern use of the Vocoder can be heard in various music albums and in main themes such as those produced by Daft Punk.

VOCODER

Modulator usually is a Voice source (but you can use as example drums and another instruments). Carrier signal (usually you can play notes with it) - synthesize signal to the Vocoder sound.

Freq Bands - Number of frequency bands (up to 24) in the filter bank. Frequency resolution of the Vocoder
Bands Shaper - Resonant bell shape mode / Flat top mode
Low Freq - Center frequency of the lowest band
High Freq - Center frequency of the highest band
Width - Adjusts the Resonance of each band
ModEnv Speed - How fast the envelope of the Modulator signal is tracked
Alt. Pan - Stereo spread / Alternate Pan band outputs (L and R)

Modulator Source (voice):
- RIGHT INPUT: Right input channel works as the Modulator, Left as the Carrier;
- STEREO MODE: L/R stereo input works as an external stereo Carrier input, LM/RM works as the stereo Modulator input;
- INVERTED MODE: L/R stereo input works as the Modulator, LM/RM works as an external Carrier input.
With STEREO connections and Inverted mode, frequency can be changed like an EQ.
Vocoder Gain - Level control of the Vocoded (processed) signal
Blend -Output control: mix between Modulator (0%), Vocoded signal (50%) and Carrier signal (100%)

Internal Carrier (Oscillator)

Amp Envelope - On/Off activity of Amp Envelope
Shift Tune - Tune oscillator waveforms
Gain - Gain volume of internal oscillator
ADSR - Attack, Decay, Sustain and Release controls of Amp Envelope
Phase Mode - Start phase of oscillator waveform for each note: reset to zero, free-running, or random
DC Blocking - Highpass filter to avoid a DC offset, especially when modulating pulse width. Adjust to taste

The Internal Carrier is an internal Oscillator with a few basic waveforms (Pulse, Tri, Saw, Sub and Noise). When using this mode the ReVoicer only uses the LM/RM modulator inputs (voice) as the modulator signal and uses the internal oscillator as the carrier. Optionally, you can connect additional External L/R Carrier inputs at same time, or just turn off this Osc.

Internal Carrier (Osc) waveforms:
- PULSE - Pulse: Level of Pulse waveform,
- Pulse Width: Width of the pulse wave. Square when set to 50%.
- Min. Width: Min. allowed widthfor pulse wave, to avoid the sound getting too thin
- SAW - Level of the Sawtooth waveform
- TRIANGLE - Level of the Triangle waveform
- SUB - Level of the quared sub-oscillator waveform (-1 oct)
- NOISE - Level of the White Noise waveform

PitchBand and ModWheel Modulation

ReVoicer Internal Osc - is sensitive to PitchBend and ModWheel.
PitchBend Range - set range of PB pitch (0..12 semi). Control placed at rear panel.
MW Amt - ModWheel amount for the selected destination parameter
MW Dest - ModWheel destination: LowFreq / High Freq / Width / ModEnv Speed / Alt.Pan / Voc.Gain / Blend

Limiter

Sometimes Vocoder effect can produce sound that can be needed in Limiter or Maximzer.
Type - Select Limiter / Maximizer mode. Maximizer boost and compress input to the limiter
Mode - Soft knee / hard knee / hard clipping
Release - Recovery time
Gain Compensate - Maximize input level (when Type of limiter = Maximizer)
