Nordsound

Precision Engineering from the Northern Frontier.

Based in Hokkaido, Japan, Nordsound is a specialized software engineering studio. We operate at the unique convergence of Creative Technology (Sound/Visuals) and High-Performance Infrastructure (Search/Backend).

Heavy Data. Light Code.

The Digital North

In a digital landscape cluttered with inefficiency, we seek the signal. Our "Nordic" philosophy drives us to build software that is robust, minimalist, and transparent.

Whether architecting a search engine for millions of records or a real-time visual system for a global event, we apply the same rigorous standard: absolute stability and speed. We believe that true creativity requires a backbone of flawless technology.

Core Competencies

A rare blend of "Soft" creative coding and "Hard" backend engineering.

High-Scale Backend & Search

We build the invisible infrastructure that powers modern platforms.

  • - Search Engine Architecture (Elasticsearch, vector databases)
  • - High-Traffic Infrastructure (AWS/GCP auto-scaling)
  • - Massive Data Handling (millisecond-response optimization)

Video Processing & Media

We treat media as data, building complex pipelines that process, analyze, and generate content.

  • - Real-Time Processing (server-side rendering, transcoding)
  • - Low-latency video distribution pipelines
  • - Computer Vision (image recognition and analysis)

Sound Programming

Audio is physics, and in the digital realm, it is mathematics.

  • - DSP (Digital Signal Processing)
  • - Sonic input to system output bridging
  • - Audio-visual synchronization systems

Products

Tools we build and share with the community.

AGTL

Audio GPU Transform Language — write once, compile to any GPU

A C-like language for GPU compute shaders, specialized for audio DSP processing. Write portable compute kernels once and compile to WGSL (WebGPU), MSL (Metal), HLSL (DirectX 12), SPIR-V (Vulkan), and GLSL (OpenGL) — powered by a TypeScript frontend and a Rust/Naga WASM backend.

  • - C-like syntax with GPU-specific primitives (__KERNEL__, __SHARED__, sync())
  • - 5 backend targets: WGSL, MSL, HLSL, SPIR-V, GLSL
  • - Two-tier compilation: TypeScript parser + Rust/Naga codegen via WASM
  • - Built for audio DSP: FFT, MFCC, spectral analysis kernels included

Native Addon macOS Open Source MIT License

au-renderer

Offline Audio Unit renderer for Node.js

Load any AU synth plugin on macOS, set parameters, send MIDI, and render audio — all programmatically, no DAW required. A native C++/Objective-C++ addon built on Apple AudioToolbox, designed for headless offline rendering at scale.

  • - Discover and load any AU synth plugin by name
  • - Full parameter control with get/set and batch rendering
  • - Sample-accurate MIDI scheduling with mono and stereo output
  • - State persistence via ClassInfo (save/restore full plugin state)

Engineering-First Creativity

Our Approach

Most creative studios struggle with scale; most system integrators lack artistic sensibility. Nordsound bridges this gap.

We are the technical partner for clients who need "Creative Tech" that actually works in production—stable, scalable, and secure.

From R&D in Hokkaido to global deployment, we deliver code that stands the test of reality.
