Audio has many uses in mobile applications. Sounds can be essential to your app; they may notify users of important events or make your app accessible to visually-impaired users. We can also use sound to help convey moods, intentions, or feelings within our apps. In fact, many companies include jingles or sounds as part of their brand.

Including audio in cross-platform apps means invoking platform-specific code. UWP, Android, and iOS all have powerful, but different APIs, to manage and play sounds. As cross-platform C# developers, we’d prefer a common API that can load audio data from a shared location.


The open-source SimpleAudioPlayer plugin provides a cross-platform C# API that can be used to load and play back audio in Windows UWP, Xamarin.Android, Xamarin.iOS, Xamarin.tvOS, and Xamarin.mac projects.

Xam.Plugin.SimpleAudioPlayer is available from To get started, add the NuGet package to each platform-specific project you wish to support. If you’re using the plugin from a shared library such as a .NET Standard lib or PCL, add the package to the library.

You can add audio files to the platform-specific projects or to a shared library. If storing in the platform-specific projects, the files are expected to be in the standard locations. For Windows UWP and Android, place the files in the Assets folder with the Build Action set to Content and Android Asset respectively.

For iOS, macOS, and tvOS, place the audio files in the Resources folder and ensure the Build Action is set to BundleResource.

Audio files are then loaded by name:

When loading audio from a shared library, set the Build Action to Embedded Resource.

Files stored in a shared library are loaded into Stream before being loaded by the plugin:

You start playback by calling the Play method.

SimpleAudioPlayer provides methods and properties to control audio playback, including the ability to stop, pause, seek, set volume, and set balance.

Playing Multiple Sounds Simultaneously

If you need to play more than one sound, the SimpleAudioPlayer plugin provides a factory method to create ISimpleAudioPlayer objects. Each object can load and play back audio independent of the others.

For an example of simultaneous playback, see the cross-platform Druminator sample app here.

SimpleAudioPlayer is open-source; if you’d like to request features, you can file an issue on GitHub, or better yet, make the changes and submit a pull request.
