Synology no longer provides software updates for DS audio on Windows Phone (starting May 11, 2018) and Windows UWP (starting May 25, 2020). For more information on the supported platforms of DS audio, please visit Synology’s official website. **You must own a Synology NAS to run this app, and be running the latest Audio Station 5.4 package to get the complete set of features** DS audio allows you to stream music stored on your DiskStation with your Windows device wherever an Internet connection is available. You can browse music by albums, artists, folders or genres, create your own playlists or share them with your friends! And if you have dedicated stereo speakers at home, DS audio can also become a remote control to stream music to them.
