Anukari

How does a physics-based synthesizer actually work? Learn by playing: every diagram in this article is a live spring-mass simulation that makes real sound.

Anukari 1.0 is out. Reflections on three years of full-time work, from leaving Google and a broken shoulder to first sound and full polyphony.

Resend's global suppression list was silently eating my customers' license key emails, so I migrated anukari.com to Postmark for deliverability.

Railway blocked my emergency deploy over dependency CVEs already live in prod, and why piling on safety checks eventually causes the outage.

Looking back at the GPU years, where my 50,000-object goal led me astray, and why one SIMD backend beats maintaining CUDA, Metal, and OpenCL.

Part 2 of the CPU rewrite, from spot-vectorizing float3 math with SSE and NEON intrinsics to restructuring loops for compiler auto-vectorization.

Anukari now runs on the CPU with hand-coded SIMD instead of the GPU. Part 1 explains the GPU origin story and the naive port that was only 5x slower.

Eight mappable macro knobs land in the UI with drag-and-drop modulation binding, plus 312ears built a Python preset API from my protobuf definitions.

The Radeon gfx90c driver aborts in clBuildProgram because it can't index kernel argument arrays dynamically. Moving them to constant memory fixed it.

Multichannel 50x50 audio I/O with near-zero overhead, ASIO support on Windows, and a workaround for a Radeon clBuildProgram crash on gfx90c.
