Moog Spectravox Semi-Modular Analog Spectral Processor Overview
An analog spectral processor based around a 10-band filter bank, Spectravox creates lively drones and colourful tonal sweeps on its own and adds resonant depth and psychedelic spectral movement to any external sound. Hook up a microphone and Spectravox becomes a 10-band analog vocoder with innovative integrated modulation of all of its filters.
An analog spectral processor based around a 10-band filter bank
Spectravox is a fascinating standalone sculptable synthesizer voice thanks to its built-in carrier sound source of a thick analog Moog oscillator and white noise generator. With its combo XLR/jack program input, Spectravox becomes a fully featured 10-band vocoder with a secondary filter bank for analyzing the spectral makeup of incoming sounds. In VOCODER mode its 10 analysis filters map the timbral characteristics of any external sound onto any other sound you can imagine. Shape the warm analog oscillator of Spectravox with the dynamics of your voice, or use a drum machine to animate guitar chords in a mesmerising broadband percussive space.
Spectravox uses the pioneering vocoding work of Bob Moog and Wendy Carlos in the late 1960s as its inspiration—work which was based on Homer Dudley's original designs from the 1930s and which was used to prominent effect in Stanley Kubrick's 1972 film A Clockwork Orange. Innovating further from these early designs, Spectravox uses 10 state-variable filters for its filter bank, all 10 of which are capable of being shifted with its internal triangle wave LFO or external control voltage. With the ability to emphasize vowel sounds via the Hiss and Buzz functionality of the Moog 16 Channel Vocoder, Spectravox is both a major step forward for analog filter banks and a loving exploration of early music technology history.
