**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.

Your music. Your server. Everywhere you go. Substreamer turns your Subsonic-compatible server into a personal streaming service. Browse, play, and download your entire music library on iPhone and iPad — free, with no ads, no subscriptions, and no data collection. Verified with Navidrome, Subsonic, Gonic, Nextcloud Music, and Ampache. Also compatible with Airsonic-Advanced, Funkwhale, Supysonic, and other Subsonic API servers. STREAM & DOWNLOAD Stream in full quality or choose a bitrate that suits your connection. Download albums and playlists for offline listening with background queue processing and automatic recovery. 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. LIBRARY MANAGEMENT Browse by album, artist, or playlist. List and grid views with alphabetical quick-scroll for large libraries. 5-star ratings and favorites sync with your server. 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. Adjustable playback speed, shuffle, and repeat. Share albums or playlists with configurable links. BEAUTIFUL & PRIVATE Light, dark, and system themes with custom accent colors. Album art color extraction for immersive detail views. No tracking, no analytics, no account required — your music stays between you and your server.
