DSP Engineering

Algorithms for inspiring audio

• Circuit analysis & emulation

  Reverse engineering and analysing classic analog hardware to build accurate digital models, capturing the character of the original circuits.

• Algorithm design

  Algorithmic reverbs, delays, chorus/vibrato, flanger, saturation, compression, granular, and more, whether modelled on analog behaviour or something entirely new.

• DAW plugins

  Building a VST/AU plugin prototype of an effect with the same algorithms before committing to hardware, so the sound can be validated and refined early.

• Embedded DSP implementation

  Porting and optimising algorithms to run in real time on industry-standard embedded hardware like the STM32H7, FV-1, or SHARC.

• Advanced processing

  Complex DSP systems beyond single-effect devices, including active noise cancellation (ANC), microphone-array beamforming, and surround/spatial audio processing.

How it's built

• Signal flow and block diagrams — mapping out the overall audio path and breaking it into functional blocks
• Algorithm design — building the DSP for each block
• DSP library — built on my personal library of proven building blocks, including delay lines, filters, oscillators, dynamics processors, FDNs, sample-rate converters, pitch detection, and more
• Plugin prototype — validating the sound in software quickly, before committing to hardware
• Port to real-time embedded hardware — optimised for the target platform, with firmware and control features such as tap tempo, MIDI, and presets

Case studies

Fiberdyne — Automotive audio

I developed audio processing algorithms and implemented them on DSP hardware for automotive OEMs and mObridge DSP amplifiers — including active noise cancellation (ANC), microphone-array beamforming, surround-sound processing, EQ, and filtering.

Stekla Engineering — Audio effect plugins

Alongside client work, I'm currently developing a range of VST/AU plugins for studio musicians and sound designers. The first release is an experimental reverb inspired by early digital hardware and is currently in private beta. I've built up an extensive C++ library of DSP building blocks and audio effects including reverb algorithms, delays, pitch shifters, compressors, and bit-depth and sample-rate conversion. Each block is written to be portable, so the same library can run in a JUCE plugin on desktop or on embedded DSP hardware like the STM32.

Why work with me on audio DSP

With my experience delivering audio products and my library of DSP building blocks, you get quick, proven results without starting from scratch.
