Moog Spectravox Analog Spectral Processor – Shut Up & Play

Alex Theakston of Mylar Melodies – In his lastest video – offers a series of creative audio demos of the Moog Spectravox, introduced ahead of Superbooth 2024.

The video demonstrates using the Spectravox to vocode, as a filterbank, as a synth voice, as an effects processor and more.

The Moog Spectravox is an analog spectral processor based around a 10-band filter bank. Spectravox can create lively drones and colorful tonal sweeps on its own, or add resonant depth and “psychedelic spectral movement” to any external sound. Connect a microphone, and Spectravox becomes a 10-band analog vocoder, with innovative integrated modulation of all of its filters.

The Spectravox was originally introduced as the Engineering Workshop project at Moogfest 2019. A key difference in the updated design is that the sliders of the original have been swapped for a row of pots, making room for additional patch points.
