Plugin.Maui.Audio provides the ability to play audio inside a .NET MAUI application.

Getting Started

Available on NuGet: http://www.nuget.org/packages/Plugin.Maui.Audio

API Usage

Plugin.Maui.Audio provides the AudioManager class that allows for the creation of AudioPlayers. The AudioManager can be used with or without dependency injection.

`AudioManager`

Dependency Injection

You will first need to register the AudioManager with the MauiAppBuilder following the same pattern that the .NET MAUI Essentials libraries follow.

builder.Services.AddSingleton(AudioManager.Current);

You can then enable your classes to depend on IAudioManager as per the following example.

public class AudioPlayerViewModel
{
    readonly IAudioManager audioManager;

    public AudioPlayerViewModel(IAudioManager audioManager)
    {
        this.audioManager = audioManager;
    }

    public async void PlayAudio()
    {
        var audioPlayer = audioManager.CreatePlayer(await FileSystem.OpenAppPackageFileAsync("ukelele.mp3"));

        audioPlayer.Play();
    }
}

Straight usage

Alternatively if you want to skip using the dependency injection approach you can use the AudioManager.Current property.

public class AudioPlayerViewModel
{
    public async void PlayAudio()
    {
        var audioPlayer = AudioManager.Current.CreatePlayer(await FileSystem.OpenAppPackageFileAsync("ukelele.mp3"));

        audioPlayer.Play();
    }
}

AudioPlayer

Once you have created an AudioPlayer you can interact with it in the following ways:

Events

`PlaybackEnded`

Raised when audio playback completes successfully.

Properties

`Balance`

Gets or sets the balance left/right: -1 is 100% left : 0% right, 1 is 100% right : 0% left, 0 is equal volume left/right.

`CanSeek`

Gets a value indicating whether the position of the loaded audio file can be updated.

`CanSetSpeed`

Gets a value indicating whether the playback speed can be changed.

`CurrentPosition`

Gets the current position of audio playback in seconds.

`Duration`

Gets the length of audio in seconds.

`IsPlaying`

Gets a value indicating whether the currently loaded audio file is playing.

`MaximumSpeed`

Gets the minumum speed that is supported on the platform the app is running on that can be set for the Speed property.

`MinimumSpeed`

Gets the maximum speed that is supported on the platform the app is running on that can be set for the Speed property.

`Speed`

Gets or sets the speed of the playback. Note: the maximum and minimum value that can be set is dependant on the platform you're running on. Setting a value that is not supported on the platform will gracefully fallback, but will not have the desired result.

To determine the supported minimum and maximum speeds at runtime for that platform you can use MaximumSpeed and MinimumSpeed.

Platform notes:

Android: between 0 and 6. Setting the value to 0 will pause playback, playback will not be resumed when incrementing the value again.
iOS: between 0.5 and 2.
Windows: between 0 and 8. Setting the value to 0 will pause playback, playback will be resumed when incrementing the value again.

`Volume`

Gets or sets the playback volume 0 to 1 where 0 is no-sound and 1 is full volume.

`Loop`

Gets or sets whether the player will continuously repeat the currently playing sound.

Methods

`Pause()`

Pause playback if playing (does not resume).

`Play()`

Begin playback or resume if paused.

`Seek(double position)`

Set the current playback position (in seconds).

`Stop()`

Stop playback and set the current position to the beginning.
