Shift — Frequency shift in Hz, −1000 to +1000. Shifts every frequency in the input by this fixed amount — not by a musical interval. A 100 Hz signal shifted by +100 Hz becomes 200 Hz; a 1000 Hz signal shifted by +100 Hz becomes 1100 Hz. This linear (non-musical) shift is what makes frequency shifters distinct from pitch shifters: musical relationships break down (a chord no longer stays a chord after shifting), but the unique “metallic / sci-fi / inharmonic” character emerges.
Dry/Wet — Equal-power blend between dry (0) and shifted signal (1). At full wet (1) the original is gone — pure shifted output. Mid values blend the original tone (preserving musical relationships) with the shifted version (adding the inharmonic character).
Additional controls
Mode — Which sideband(s) to keep:
- Up — shifts only the upper sideband (positive shift only, even if shift is set negative). Cleaner, more controlled effect.
- Down — shifts only the lower sideband (negative shift only).
- Both — combines both sidebands (more dramatic, sometimes ring-modulator-like character with phasing artifacts).
For musical use, Up or Down alone (depending on direction); Both for sound-design experimentation.
About Frequency Shifter
Pitch shifting (semitones) preserves musical intervals — a chord stays a chord, harmonics stay harmonic. Frequency shifting (Hz) breaks those relationships: every frequency moves by the same Hz amount, so the harmonic ratios change. The result is a uniquely “wrong but interesting” character — sounds become inharmonic, slightly metallic, dream-like, or alien. Use it for: special effects on vocals (the classic Bode/Moog frequency-shifter sound), sound design where you want non-musical detuning, ring-modulator-style timbres without an external modulator, or for adding clangorous shimmer to clean tones. Compare with pitch-shifting nodes (Pitch category) which preserve musical intervals.
