// WHO WE HELP

Built for people who take audio seriously

We work with three kinds of clients:

01

Audio software companies

Expanding product lines with plugins or standalone audio software, without the overhead of full-time hires.

02

Musicians & producers

With a plugin idea they want to bring to market, handled end-to-end from concept to commercial release.

03

Music tech startups

Building serious tools and needing architecture that won't collapse the moment real users hit it.

Whether you're starting from scratch or rescuing an existing product, we help you move faster and avoid the mistakes that derail most audio projects.

What We Build

Audio Plugin Development (VST3, AU, AAX)

We design and build professional audio plugins ready for real-world use. From concept to release, we handle the full development cycle:

  • > Cross-platform plugins (macOS / Windows)
  • > VST3, AU, AAX formats
  • > JUCE-based development in modern C++
  • > Custom DSP and real-time audio processing
  • > Works reliably across Ableton, Logic, Pro Tools, etc.

Built to perform under pressure: stable, efficient, and ready to ship.

Start Your Plugin Project

DSP Optimization & Plugin Performance

If your plugin is unstable, CPU-heavy, or difficult to scale, we fix it. We specialize in:

  • > Reducing CPU usage and improving efficiency
  • > Fixing crashes and edge-case bugs
  • > Optimizing real-time audio performance
  • > Refactoring legacy JUCE / C++ codebases

We turn fragile systems into reliable products.

Audio AI & Machine Learning

We integrate machine learning into real-time audio systems.

  • > Audio analysis and event detection
  • > Generative audio systems
  • > Real-time ML pipelines
  • > Integration with C++ and DSP workflows

Bringing modern AI capabilities into production-ready audio tools.

Custom Audio Software Development

Beyond plugins, we build full audio applications and systems.

  • > Desktop audio applications
  • > Internal tools and DSP systems
  • > Real-time audio engines
  • > API and backend integrations

Designed for performance, scalability, and long-term maintainability.
