What We Build

Nullform Audio develops studio-grade audio plugins for macOS and Windows.

Modelled from real hardware. Built for professional workflows.

Core Focus Areas

Analog Modelling

Circuit-level analysis of hardware EQ, saturation and dynamics — faithfully recreated in software.

Precision Engineering

Calibrated frequency response, zero-latency processing and low CPU footprint across all plugins.

Tone Shaping

EQ curves, harmonic saturation and gain-dependent behaviour that respond like real hardware.

Cross-Platform

VST3 and AU on macOS, VST3 on Windows — seamless integration with every major DAW.

Products

Plugins designed for precision tone-shaping and professional workflows.

PentaGraph

5-Band Graphic EQ Plugin

A studio-grade 5-band graphic equaliser modelled on the classic analog circuits found in legendary guitar amplifiers. Calibrated from real hardware measurements, PentaGraph delivers authentic analog EQ behaviour with band independence, gain-dependent Q, and subtle saturation.

  • Five fixed bands: 80 Hz · 240 Hz · 750 Hz · 2.2 kHz · 6.6 kHz
  • Parallel summing topology for true band independence
  • Analog-modelled saturation via anti-aliased soft clipping
  • Calibrated from real hardware measurements
  • VST3 & AU on macOS · VST3 on Windows

DecayChain

Bit-Crusher & Wavetable Distortion Plugin

A modern bit-crusher and wavetable distortion plugin with 265 original wavetables, preamp/tone stage, flexible bit logic pre or post the wavetable mapper, table morph, envelope routing, and dual DSP modes (Legacy & ADAA).

  • Bit-crusher with Depth and Mask modes · Pre/Post placement
  • 265 procedurally generated wavetables with hex index & morph
  • Preamp, tilt EQ, sample-rate reducer, envelope routing
  • Dual DSP: Legacy (lo-fi) and ADAA (anti-aliased)
  • VST3 & AU on macOS · VST3 on Windows

"We model the circuit, not just the curve."

Our Approach

Every plugin starts with real hardware — measured, analysed and understood before a single line of code is written.

We believe the best digital tools are the ones that disappear into your workflow. Low CPU, zero latency, and the kind of analog character you can feel — not just hear.

About Nullform Audio

Nullform Audio builds studio-grade audio plugins that bridge the gap between analog character and digital precision. We start with real hardware: measuring, analysing, and understanding the circuits that defined classic tone, then faithfully recreating that behaviour in software. Every plugin is engineered for low CPU usage, zero-latency operation, and seamless integration into professional workflows.
