Wave Shifter: Frequency Shifter Effect Plugin by Minimal Audio

Wave Shifter covers three core processing modes. Frequency shifting moves every partial in the input by the same amount, which produces inharmonic, metallic results. Ring modulation and amp modulation offer related but distinct behavior for tremolo-style and sideband effects.

The frequency controls are where most of the shaping happens. BPM sync locks the shift rate to tempo, tuned note values set pitch-based shifts, and stereo spread widens the effect across the field. Feedback and time controls then add resonances, comb filtering, and cascading delays.

Internal FM is one of the plugin's distinguishing features. The internal oscillators can be modulated by seven FM sources, including tuned operators, filtered noise, feedback routing, and an external sidechain input, so any incoming signal can be used as a modulation source.

Soft sync forces the internal oscillators to follow the input signal, which the developer positions as a way to create distinctive distortion. A built-in morphing LFO adds rhythmic and randomized movement, with adjustable waveforms and stereo offset for evolving textures.
