DSP, analogue modelling, embedded hardware, electronics, product design and plugins, from first principles to finished product.

see how we work →see product design

We research, design and build audio technology: the algorithms, the circuits, the firmware, the boards, the enclosures and the software that brings them together.

Audio and plugin software

Audio plugins and the software around them, from signal processing to licensing.

Product design

3D modelling and prototyping for consumer audio, guitar amplification and drum triggers.

Audio product development

Audio products taken from concept through development to release.

Bespoke software

Software built to a specific brief, covering the full project lifecycle.

How we research and innovate in audio and electronic design. Each discipline feeds the next: the maths, the circuit, the code on the device, the board it runs on and the interface people use.

DSP and algorithms

We research and develop signal processing: filters, dynamics, effects and analysis. Each algorithm is worked out in the maths first, then written as efficient real-time code.

  • Filter and effect design
  • Spectral analysis
  • Real-time optimisation

Analogue modelling

We analyse analogue circuits component by component and model their behaviour in software, so a plugin responds the way the hardware does.

  • Circuit analysis
  • Non-linear modelling
  • Measured against hardware

Embedded hardware

We write firmware for microcontrollers and DSP chips that process audio on the device, sample by sample, within a fixed time budget.

  • Firmware
  • Real-time audio on device
  • Low-latency buffering

Electronic design

We design the schematics and printed circuit boards for audio products and take them from prototype to manufacture.

  • Schematic capture
  • PCB layout
  • Prototype to production

Plugin and interface design

We design the interfaces musicians use: plugin layouts, controls, meters and displays that make the processing underneath clear and quick to use.

  • Plugin UI design
  • Controls and metering
  • Audio software UX

We design the physical product as well as what runs inside it: industrial design, 3D modelling and working prototypes for consumer audio, guitar amplification and drum triggers.

Sketch

Concept sketches set the proportions, the control layout and how the product will be used on stage, in the studio or at home.

  • Concept sketches
  • Ergonomics
  • Control layout

3D model

Enclosures, panels and controls are modelled in CAD, so every part has exact dimensions before anything is made.

  • CAD modelling
  • Enclosure design
  • Tolerances

Engineering

The model is built around the electronics. The DSP, control, power amplifier and power supply boards are placed in the chassis and checked for fit, heat and access, with the speakers in the cabinet below.

  • Internal layout
  • Electronics integration
  • Assembly

Prototype

Parts are 3D printed or machined and assembled into working prototypes for testing before production.

  • 3D printing
  • Working prototypes
  • Design for manufacture

Deep thinking.

We delve into systems and processes to find weaknesses, root causes and the best solution.

Straight talking.

Honest, jargon-free communication with colleagues and clients keeps projects aligned.

Hard working.

Understanding a problem is not enough. We deliver the solution and take pride in it.

Our office is a converted Victorian umbrella factory in Leicester.
