The operator behind this.

What I've shipped

I've spent 25 years in professional audio, most of it building products and companies rather than writing about them.

I was the first employee at Grace Design, hired in 1997 to build cables. Over about four years I helped it grow from a small shop to roughly twenty people and around four million in revenue. Then HeadRoom, where I started on the floor and worked up to President and CEO. When our investors wouldn't fund new products, I converted the company to employee ownership so the staff kept their equity and their jobs, and we ran it until ecommerce flattened the specialty headphone market. Along the way I co-directed the HeadRoom Cosmic, a headphone built for recording engineers. I couldn't draw it, but I could steer it through three prototypes and about fifty scrapped iterations to the thing I wanted.

Today I run Warren Labs, my own audio brand. I started with Level, an audio plugin I built by directing Claude Code, validated against Apple's auval suite (11 of 11 passing) and an 80-test DSP harness I had Claude write, then rounded out a foundational suite of plugins on that same base. Tone Farm, a self-branded guitar amp-and-effects rig, is my first real flagship effort built on that foundation. It's substantially built, with pricing and final validation still to settle before it ships. Changes, an iOS app that turns a rough recording into a session-ready chart for Logic Pro, is built and waiting on Apple Developer Program approval before it can ship. I wroteThe Art and Science of Headphone Design, and I run makerphones, an open-source, 3D-printable headphone project. At Maestrooo, where I'm Director of Support, I built an AI support tool that's replacing a paid vendor, now in testing with my team.

I've also built Sonic Bloom, an all-in-one site and fan-engagement platform for working musicians, still in its early days.

I'm not the deepest DSP engineer or the strongest coder in the room, and I don't pretend to be. I'm a builder with 25 years of judgment who now ships products by directing Claude instead of hand-writing every line.

Why Sparkfile

I spent years pitching ideas inside companies and getting shot down for lack of resources. I tried building them myself and hit the same wall. That's not true anymore. Claude Code, Claude Design, and the rest of what Claude ships let me build, practically overnight, things I used to only dream about or spend real money and months of my own time on: web design, apps, logos, content. And it keeps getting better, fast. Sparkfile is where I show operators exactly how, using the real things I'm building, not toy examples.

How I use Claude

Claude Code writes most of my code. I direct it. That's how I built Level, the DSP test harness, Tone Farm, Changes, Sonic Bloom, and the Maestrooo support tool.

I keep memory files Claude reads before it works: an operating guide, voice notes, project context. This site's VOICE.md is that same practice.

The stack I direct Claude across: JUCE for C++ audio plugins. Laravel, Livewire, and PHP. The Anthropic SDK. And pgvector with Voyage embeddings for retrieval. Filesystem MCP wired to my projects folder so Claude works on real files. GitHub Pages and Actions for shipping.

The skill is informed direction. I know what to build, and I know when the AI's approach is wrong.
