Stemacle

Split songs into stems, lock loops to tempo, shuffle compatible tracks, and export everything without uploading your music.

The web app is instant. The desktop app adds indexed libraries, model caches, higher-quality local splitting, downloads, background jobs, and export queues. iOS is in progress, and the public release path stays tied to the stem-player repository instead of a separate workspace.

The public `stem-player` workflow runs tests plus site and native bundle prep before deploy.

desktop app

Quiet power around the same physical control.

Stemacle Desktop keeps the circle, then adds the things a browser should not pretend to own: indexed folders, persistent caches, background splitting, native exports, and release builds.

index: Track local folders, keep metadata on disk, and rescan without rebuilding the library by hand.
split: Preview stems are built in. High-quality mode plans and runs Demucs locally when installed.
cache: Model, analysis, and export caches stay on disk so repeat work is fast and predictable.
download: Pull compatible audio into the same queue, then export manifest-backed stem packs for future sessions.
private: Files stay on your machine. No upload account sits between you and the track.

public repo, public workflow

Built from stem-player, not a private workspace.

The landing page points to the public repository and the public release artifacts. The Validate workflow runs on pull requests to main, pushes to main, and manual dispatch, then prepares the same site and native bundles the release path depends on.
