+# AURA Engine
-AURA Engine does:
- * request the radio-program from an external source
- * switch the soundserver at the correct time to a given source for a specific show
- * record what is broadcasted
- * stream to an icecast server
- * play to line-out
+Aura Engine is a play-out engine as part of Automated Radio (Aura) system,
+specifically build for the requirements of community radios.
## Features

+### Play tracks from multiple sources

+It's possible to air playlists with music or recordings stored on the **filessystem**,
+via external **streams** or live from a **studio**.

+The engine offers a simple way to detect scenarios where no music is on air.
+It possible to configure the sensitivity of the Silence Detector and automatically
+transition play-out to a Fallback Playlist (see Auto Pilot).

+### Auto Pilot

+In case there is no schedule delivered by Steering, engine provides multiple
fallback handling scenarios. The available fallbacks are evaluated in following order:
-1. **Timeslot Fallback**:
