The VST years were a Windows story. My current audio experiments live somewhere else entirely: on Linux, inside the PipeWire graph, written in Go — and the parallels to the old days are almost comically direct.
PipeWire tools
pw_convoverb is a convolution reverb for PipeWire. Convolution has followed me since the very first HRTF 3D plugin and the crosstalk cancellation experiments — the same mathematics, now running as a node in a modern audio graph instead of a plugin in a 2005 host. pw-comp is a compressor with a soft knee and a small TUI control interface; its ancestors are the dynamics plugins of the open source project, and the Behringer Composer measurements that once taught me what compressor curves really look like.
Quadraphonic time travel
My favorite recent rabbit hole: go-sq-tool, a standalone decoder and encoder for SQ — the matrix quadraphonic format of 1970s vinyl. Two decades ago I wrote Quadropolis and Tina-Turner, plugins that simulated quadraphonic sound over headphones and four speakers. Now I decode the real historical format. Some interests simply refuse to die.
And the VST thread?
Still alive too: I have been working on vst3go, a VST3 plugin framework in Go — closing a loop that started with Toadstunnel. Add a text-to-speech engine in pure Go (go-pocket-tts — safetensors inference without Python or ONNX Runtime) and a nature-inspired optimizer (mayfly, an heir to my old differential evolution library), and the drawer of small sharp tools looks much like it did in 2008. Only the operating system changed.
