Fault

Unfiltered Audio

Fault is a stereo spectral shifter that combines pitch shifting, frequency shifting, and modulation into a single multi-effects plugin. It can subtly enhance tracks or radically transform audio through frequency-modulated effects, dual-channel processing, and cross-channel feedback. With its flexible modulation system and six feedback paths, Fault excels at everything from transparent pitch correction to extreme sound design and creative synthesis.
