What Klangraum does

Klangraum is being prepared for its first App Store release. There is no download link yet.

Your libraries in one place

Klangraum connects approved audio libraries without uploading them to someone else's cloud catalogue. Server, account, and source remain visible while search and the playback queue work across them.

Built for music and long-form audio

Albums, artists, tracks, playlists, audiobooks, and audio dramas use library and resume behavior suited to their content. Movie, TV, and photo libraries are not imported.

Direct playback and offline listening

The app prefers Direct Play and can request a compatible alternative from the server when needed. Selected tracks can be validated, stored on the iPhone, and played without unnecessary server requests.

Local music stays local

You can import audio files with the iOS document picker or, after granting permission, include locally playable items from Apple Music Library. Klangraum does not upload this content to your music servers.

No tracking account

Klangraum operates no separate user account, contains no advertising, and uses no tracking or analytics SDK. Credentials are protected in the iOS Keychain.
