Add Frequalizer to the Open Audio Stack registry

[kmturley]

Hello!

We are curating a list of open-source audio software at Open Audio Stack. We've created an open registry and package manager for installing/upgrading audio plugins, apps, presets and projects (think npm/Homebrew, but for audio software). We'd like to include Frequalizer, but it requires a few small changes.

Requirements checklist: (last checked 2026-07-18)

• License specified as a LICENSE file, SPDX/REUSE annotations, or a clear statement in the README — BSD-3-Clause
• GitHub release with downloadable binaries (zip/tar/exe/dmg/deb — source-only releases don't count), tagged with a fixed date or semantic version — no releases published yet
• Preview image in the README or repo — a UI screenshot, or a logo/icon if the project is headless — the only images found (FB-logo.png, GitHub-logo.png) look like social/sponsor badges rather than a screenshot or app icon of Frequalizer itself

Once everything above is checked off, Frequalizer can be added automatically — no further action needed from your side beyond that. If any box looks wrong (e.g. we missed an existing license or image), add a comment to this issue and we'll correct it. And if you'd rather this project not be listed at all, feel free to close this issue — we'll leave it alone.

Thanks!
