Innsbruck · Audio software
We build audio plugins that do the actual physics instead of imitating the result. A speaker model that moves a cone. A codec that really runs out of bits. A retuner that finds the interval before it snaps a note. Every claim on this site is a number one of our test suites prints.
VST3 · CLAP · AU · LV2 · Standalone — macOS on Apple Silicon. Windows builds in progress.
hear it where it lands
A physical model of a small speaker being driven too hard, and the protection DSP trying to save it.
make it survive the internet
A real transform codec you can starve, plus generation loss and packet loss no encoder does on purpose.
any loop, your key
Live retuning that moves a loop into your key with the chord structure intact — including maqam, makam and raga.
01
An imitation of an artifact only holds at the setting it was tuned at. A model of the thing that causes the artifact holds everywhere, including at settings nobody thought to check. It costs more to build once and stops being wrong afterwards.
02
Latency is measured by cross-correlation against the figure reported to the host. Transparency is measured in dB. CPU is measured as a share of one core. If a suite prints a number, that number goes on the page — and if it moves, the page moves with it.
03
Everything is built on the DISTRHO Plugin Framework: ISC licensed, no revenue cap, no EULA, clean-room VST3 headers so no third-party licensing attaches. The DSP and the editors are written from scratch. Nothing here can be repriced or withdrawn by a supplier.
04
No plugin here is named after, measured from, or matched to anything anybody sells. No published bitstream format is implemented. Excursion's test suite fails the build if a trademark reaches a preset name — the constraint is enforced by machine, because a constraint that depends on remembering is not one.
