Sunsine Audio Harmonic Decoder


The Harmonic Decoder can sound like a fuzz, an octave/harmony pedal, a filter/wah, a complex waveshaper or some crazy bent 8 bit glitch box but all of it’s effects are derived from an analog VCO, a phase detector, and a simple filter in an arrangement known as a Phase Lock Loop (similar to the much more elaborate, long out-of-production SCHUMANN PLL).

At the heart of the Harmonic Decoder is a true single oscillator analog synthesizer. It effectively resynthesizes any signal delivered at the input, providing extreme waveshaping and harmonic effects in the analog domain.

The frequency of the VCO can be modulated either by the internal envelope follower or via the external control voltage input.
