Spectral Audio Effect

SpectrumWorx

SpectrumWorx is a modular spectral effect: it decomposes your audio into the frequency domain, lets you stack and chain effects on that spectrum, then resynthesizes the result. Originally developed by Little Endian and open sourced in 2024, it now runs as CLAP, VST3, and AU on Windows, macOS, and Linux.

Work in progress. Nightly builds are a modernization sprint, not a finished release. Expect rough edges.

It is reachable at /spectrumworx but does not appear on the home page or in either navigation menu, because both are generated from theprojects content collection and SpectrumWorx has no entry in it.

To make it live, create src/content/projects/spectrumworx.jsonalongside the other project files (title, order,summary, cover, categories,issue_tracker, repo), add"spectrumworx" to the exclusion list insrc/pages/[project].astro so this hand-written page wins over the generated one, then delete this box.
