Show HN: Audiomass – a free, open-source multitrack audio editor for the web | Hacker News

Audiomass, a free open-source web audio editor, was introduced on Hacker News.

It supports browser-based multitrack editing, quick edits, and session export to .amss files.

The app is frontend-only, with optional track caching via IndexedDB and no backend.

Its lightweight, privacy-focused design makes basic audio work possible without server dependence, though browser limits still apply.
