A brief, stereotypical vocoder demo featuring the amazing Sennheiser VSM 201 Vocoder with an EML POLYBOX. These were both units that were in for repair at The Analog Lab in NYC. The tone generator is routed through the EML where it is divided into user selected pitches/chords. The chords remain static, but the pitch shifts with the change of the frequency of the tone generator.
Sennheiser Vocoder VSM201
made in 1978
this is a luxury 20bands vocoder
of course only the “creme de la creme” used THIS, because it is really not cheap.. Kraftwerk!
The vocoder was first a military device to encode speech signals
Josh Tallman demos the vocoder – Electrix Warpfactory:
Designed for both DJs and Musicians, the Warp Factory is possibly the ultimate stand-alone Vocoder. With those great big knobs, the Warp Factory is designed for straight-forward hands-on use. It has an XLR Mic input (conveniently located on the front) and a quarter-inch line input for use as the Formant or carrier signals. Then there are two quarter-inch line-inputs and two RCA phono inputs for your stereo source sounds, either drum loops, mixes, songs, synth pads, etc…
The way it works is whatever Formant signal you have, say your voice, will be warped into taking on the characteristic of the Source signal you have, say a buzzy synth sound. This would in effect give you that Robot voice effect.
The Warp section is where you’ll find most of the knobs and cool features of the Warp. There is a low- and high-pass filtering switch. A ‘Gender’ knob adjusts the pitch of the Formant. ‘Q’ adjusts the width of the filtering. An ‘Order’ adjusts the filter resolution for clear to abstract vocoding effects. There is also Noise and a built-in oscillator Source signal whose pitch is adjusted by ‘Robot Pitch’. Various Bypass and Freeze switches and complete MIDI implementation make this the ultimate Vocoder for DJs, musicians and producers.
For this short improvised demo, the author has used internal programs and mixes from preset and Hollow Sun banks.
Here are the details:
8 tracks recorded in audio live in Presonus Studio One Artist v 1.6.5:
– mix “DANGER” (rythmics)
– Pea PG Vox (relatively close to the “human choir” of the Roland VP330 with no strings)
– imported sample : PolyMoog Vox Humana for bass and lead parts
– mix “high pass heaven”
– mix “trancin” with arpeggiator
– ambiance + chorus
– Sounds Fx 1 and 2

Strange Attractor is a truly novel sound generator based on chaos theory. The outcome of PhD research, it uses a feedback system to process and generate sound. Unlike conventional synthesis techniques, sounds emerge in surprising and unexpected ways, almost having a life of their own. By moving your finger on the screen, you can navigate through a space of evolving sounds, that build-up, pulsate, and decay. Sound input through the microphone or headphone socket can be processed into fractal textures, or will trigger and control oscillations.
Voco is a touch controlled phase vocoder. Sounds can be manipulated by touching the screen, and played like like an instrument. Time is represented on the horizontal axis, and pitch on the vertical. The yellow bars display the sounds intensity. Sounds can be sampled through the microphone or headphone socket, or loaded via iTunes. There are also features to constrain the pitch to different scales, and to glide the playing point around the screen to make rhythmic loops.
Now available as VST and Standalone
G-Storm Plugins announces the release of VSP-330 version 2.0 Voice Synth Plus VST plugin and standalone version. The VSP-330 is a recreation of the rare and nearly extinct VP-330 string ensemble and human voice formant choirs. The emulation is made possible by synthesis and effects DSP techniques, not samples.
Roland VP-330 Vocoder: The vocoder shapes its envelope and filters by any sound source fed into it, your voice or even a drum loop can be used which is then applied to another sound source, typically a synth pad. This creates a very unique and famous robot-like sound.
Aside from the 10-band vocoder, the VP-330 added a string synth section, choir and a human-voice sound, both of which are quite excellent themselves. Its 3 sound sections offer a few different presets that can be slightly edited with de-tuning and vibrato. The VP-330 is one of the best Vocoder synths ever and although there are many other types of Vocoders, none sound as good as this!
And here are the details:
Hello. My name is Mars. Today we’ll talk about vocal processing through a vocoder. Daft Punk have used this technique in many of their tracks.
I have searched for a long time to find a convenient and easy vocoder, and tried many different devices. When we started work on the PLAYMA track “Cuz We Are PLAYMA”, the vocals weren’t catchy enough, and at the time I had not had the opportunity to ask some of my friends to record vocals for me. I decided to try recording them myself, even though I don’t like my voice.
For the record, I used a standard iPod headset. That sounded funny and my voice was so wrong. Here I was not even in tune, but it’s ok for this example.
To begin, compress the vocal track a little bit to cut some peaks in the sample, then use the vocoder effect. In order to implement this effect, I first need to make a synth, which fills out my voice. For this I used a standard preset of “NI Massive” synth.
To create a melody for the synth, I copied the midi clip, which I used to lay down the guitar track. The Vocoder effect is very simple to use. To make it work you just need to select the source channel as the Massive synth. After this you should tweak up the effect a little for a more pleasant sound.
Next, add a slight delay between the left and right channels to spread the stereo, and cut low frequency a little bit.

iVoxel – The Singing Vocoder now totally revised with tons of new features. Pitch tracking with automatic pitch correction to selectable scale, polyphonic sequencer, virtual MIDI and background audio, …
“iVoxel is not only an amazingly sounding vocoder – the unique concept of iVoxel turns this vocoder into a singing machine. iVoxel is a combination of a voice optimized synthesizer and a vocoder. The vocoder part is based on the Matrix vocoder from VirSyn used by many famous artists – one of them the well known german group Kraftwerk. The channel filters used by iVoxel are based on the Sennheiser Vocoder VSM201 resulting in a rich and fat analogue sound characteristic. The pitch follower and automatic tuning let you sing correct to a selectable scale.”
New in version 2
- Realtime pitch following.
- Automatic tuning correction to selectable scale.
- Polyphonic sequencer.
- Voxel editing.
- Hi-end Reverb.

- Support for Korg’s Wireless Sync-Start Technology (WIST).
- Publish recordings online with the SoundCloud audio platform.
- Many more things and bugfixes.

Charlie Chaplin speech from The Great Dictator run through a Bode Vocoder. SCI Prelude used as the carrier signal.
In 1979 Moog released a vocoder of their own, although its design and architecture is almost identical to the Bode 7702 vocoder. It’s a 16-band analog vocoder which separates a given synthesizer sound (carrier signal) into seperate frequncy bands ranging from 50 to 5080 cycles per second. It does not have any internal oscillators so it is designed to be used as a processor for external carrier and modulator wave sources. The modulator is typically a vocal or drum beat used to modulate the carrier/synth sound being processed.
It has microphone and line inputs as well as 16 synthesizer inputs (1 for each frequency band) and 16 outputs. This 16 channel cross-matrix patching system is cumbersome, but useful during the modular synth era, allowing for full external patching between synth and vocoder sections. Other features include a high-frequency bypass, a short 6ms response time for capturing fast percussive sounds, sample-and-hold, and a global bypass switch to turn off the vocoding effect. Unfortunately there is no output mixer, MIDI or CV/Gate.
