The largest chunk of my current work is a family of DSP libraries under the algo-*<\/strong> umbrella — the direct descendant of two decades of audio and acoustics work, rebuilt in Go.<\/p>\n\n\n\n

The core<\/h2>\n\n\n\n

algo-dsp<\/a> is the heart: production-quality DSP algorithms for Go, deliberately algorithm-centric and transport-agnostic — no UI, no audio device, no file format dependencies. Just the math, tested and benchmarked. Underneath it sits algo-fft<\/a>, an FFT with hand-written assembly where it counts.<\/p>\n\n\n\n

The satellites<\/h2>\n\n\n\n

Around the core, the suite splits by domain: algo-vecmath<\/a> for SIMD vector math, algo-pde<\/a> for spectral PDE solvers, algo-approx<\/a> for fast function approximations, and algo-acoustics<\/a> for room acoustics.<\/p>\n\n\n\n

Instruments<\/h2>\n\n\n\n

The newest branch is physical modeling and synthesis: algo-piano<\/a>, algo-glockenspiel<\/a>, and a drum machine (algo-drum<\/a>, in TypeScript, because instruments want a UI).<\/p>\n\n\n\n

Try it in the browser<\/h2>\n\n\n\n

Much of the suite compiles to WebAssembly, so you can hear and see it without installing anything: a step sequencer<\/a> driven by algo-dsp, an interactive FFT explorer<\/a>, an acoustic room-modes lab<\/a> that solves the Helmholtz equation live as you move the source, and the playable instruments — piano<\/a>, glockenspiel<\/a> and drum machine<\/a>.<\/p>\n\n\n\n
