AuxFormant
Vocal Pitch, Formant & Robotic Transformer
AuxFormant is an ultra-low-latency, zero-phase-tear vocal transformation workstation. Shift pitch up to ±24 semitones and morph vocal tract length independently without altering pitch, from deep masculine chest resonance down to bright feminine and helium chipmunk textures.
Where AuxFormant Excels
Designed for immediate vocal impact in hip-hop, modern pop, electronic, and sound design sessions.
Modern Trap Octave Doubles
Pitch vocals down -12 semitones while pulling throat resonance down -5 semitones. Blend in 50% under the lead vocal with modeled tube drive for the unmistakable deep, atmospheric modern ad-lib sound.
Scale-Snapped Pitch Glides
Engage Quantize mode and set your song's Root Key and Scale. The real-time YIN pitch tracker snaps incoming melodic vocal notes to clean harmonic intervals with adjustable glide speed.
Robotic French-Electro Vocoding
Switch to Robot mode to lock vocal pitch to a fixed drone frequency or control it live via incoming MIDI notes for futuristic Daft Punk-style electro textures and robotic hooks.
Zero-Phase-Tear Vocal Transformation
Every algorithm inside AuxFormant is tuned to preserve transient clarity, breath, and natural performance dynamics.
Signalsmith Stretch Engine
State-of-the-art polyphonic pitch shifting with peak-tracking phase vocoder technology. Eliminates phase smearing, metallic artifacts, and chirping across the entire ±24 semitone range.
Shift: ±24 SemitonesIndependent Formant Shifting
Modify the acoustic resonant frequencies of the vocal tract independently from musical pitch. Shift from deep chest resonance to bright head voice, or engage Link mode for authentic analog tape varispeed.
Morph: ±12 SemitonesReal-Time YIN Scale Quantizer
Sub-millisecond fundamental frequency tracking automatically detects incoming pitch and snaps it to your chosen musical scale (Major, Minor, Pentatonic, Dorian, Blues, Chromatic) with adjustable snap speed.
Algorithm: YIN AutocorrelationRobot / MIDI Vocoder Mode
Monophonic fixed drone mode collapses vocal intonation to a single pitch or incoming MIDI note values, transforming natural speech or singing into robotic, monotone vocoder textures.
Control: Manual / MIDI InModeled Triode Tube Drive
Integrated analog saturation circuit modeling 12AX7 vacuum tube harmonics. Injects warmth, grit, and harmonic edge to cut through dense modern electronic and pop arrangements.
Color: 2nd & 3rd HarmonicsStereo Haas Spreader & Blend
Psychoacoustic micro-pitch detuning and Haas delay expands mono vocal tracks into lush, wide stereo fields (0% mono to 200% ultra-wide) with full parallel dry/wet balance.
Stereo: 0% – 200% WidthParameter Specifications
