Distortion That Cuts Through Any Mix

HellFold is a phase distortion engine designed for producers who demand aggressive, unique character in their sound. Whether you're crafting crushing metal guitars, industrial basslines, or experimental textures, HellFold delivers distortion that stands apart from any amp sim or saturation plugin.

15 Distortion Algorithms

From smooth saturation to extreme digital destruction — each algorithm responds differently to Drive and Control parameters. Click any algorithm to learn more.

Phase Fold Modulation

Unlike traditional distortion that clips or saturates amplitude, Phase Fold manipulates the timing relationships within your signal — creating harmonic complexity and movement that sounds fundamentally different from any conventional distortion.

Oct Fold Subharmonics

Generate subharmonics one octave below your input using YIN pitch detection. Creates organic, musical sub-bass that tracks the original pitch — perfect for massive bass drops and low-end reinforcement.

Dual EQ System

3-Band Parametric EQ with full Gain, Frequency, and Q control — route PRE or POST distortion. 5-Band Graphic EQ for quick tone shaping at 100Hz, 250Hz, 1kHz, 3.5kHz, and 10kHz.

Additional Features

Real-Time Oscilloscope — Visualize input, output, and Oct Fold signals with adjustable settings.

A/B Comparison — Store and toggle between two complete parameter states.

66 Factory Presets — Professionally designed starting points for any genre.

Audio-Reactive Visuals — Cursed temple aesthetic with optional fire, lightning, and circuit effects.

Up to 8x Oversampling — Pristine anti-aliasing for clean high frequencies.
