Welcome Spectra, a new powerful 16-band spectral processor module that brings creative filtering in the free VCV rack modular software Synthesizer.

I repeat myself but the free modular software Synthesizer VCV Rack is growing and growing. With Spectra, Andrew Belt released a new 16-band spectral processing module that features two filter bank models and a powerful modulation section over all frequency band responses.

Spectra can be used in a very musical way as a vocoder, VCF, fx processor or even for refining sounds as colourful graphic EQ.


It is modeled on the 296r Spectral Processor but also includes an ideal digital model with a more transparent character.

Spectra can be used as a vocoder, a colorful graphic EQ, a VCF for synth voices, a transient generator for percussion, and an external FX processor. As usual, virtually every parameter can be externally controlled with CV signals.

Many hardware spectral processor modules allow cross-modulation between two units via a bus cable behind their panels. Spectra supports this via an “auxiliary” input, which emulates an additional 16 bands for modulating the amplitudes of the 16 main “carrier” bands. This feature allows Spectra to be used as a vocoder without manually patching a second instance.

VCV Rack Spectra is available now for purchase for $30 USD from the official VCV Rack store.
