**You must own a Synology NAS to run this app, and be running the Audio Station 6.5.0 package to get the complete set of features** DS audio allows you to stream music stored on your DiskStation with an iPhone/iPad wherever an Internet connection is available. Better yet, with the offline mode you can listen to songs stored in the device’s local memory for when no network connection is available. You can browse music by albums, artists, folders or genres, create your own playlists or share them with your friends, and even rate your music! And if you have dedicated stereo speakers at home, DS audio can also become a remote control to stream music to them.

Substreamer switches to offline mode automatically when your server is unreachable. TUNED IN — SMART MIXES Personalised playlists powered by your listening history. Time-of-day mixes, deep cuts from similar artists, decade time machines, genre blends, favorites radio, and a custom mix builder — all generated from your own library, not an algorithm trained on someone else's taste. LISTENING ANALYTICS See your play history, top artists, albums, and songs, most active listening hours, activity heatmaps, and listening streaks. Scrobbles queue locally when you're offline and sync automatically when you reconnect. Exclude specific albums or artists so one-off plays don't skew your stats.

Create and manage playlists, reorder tracks, or save your current queue as a new playlist. PLAYBACK Background playback with full lock screen and notification controls.
