This article demonstrates how to embed audio frames and control playback with **Aspose.Slides for .NET**. The following examples show basic audio operations.

## **Add an Audio Frame**

Insert an empty audio frame that can later hold embedded sound data.

```csharp
using Aspose.Slides;

static void AddAudio()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    // Create an empty audio frame (audio will be embedded later).
    var audioFrame = slide.Shapes.AddAudioFrameEmbedded(50, 50, 100, 100, new MemoryStream());
}
```

## **Access an Audio Frame**

This code retrieves the first audio frame on a slide.

```csharp
using Aspose.Slides;

static void AccessAudio()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    slide.Shapes.AddAudioFrameEmbedded(50, 50, 100, 100, new MemoryStream());

    // Access the first audio frame on the slide.
    var firstAudio = slide.Shapes.OfType<IAudioFrame>().First();
}
```

## **Remove an Audio Frame**

Delete a previously added audio frame.

```csharp
using Aspose.Slides;

static void RemoveAudio()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var audioFrame = slide.Shapes.AddAudioFrameEmbedded(50, 50, 100, 100, new MemoryStream());

    // Remove the audio frame.
    slide.Shapes.Remove(audioFrame);
}
```

## **Set Audio Playback**

Configure the audio frame to play automatically when the slide appears.

```csharp
using Aspose.Slides;

static void SetAudioPlayback()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];
    
    var audioFrame = slide.Shapes.AddAudioFrameEmbedded(50, 50, 100, 100, new MemoryStream());

    // Play automatically when the slide appears.
    audioFrame.PlayMode = AudioPlayModePreset.Auto;
}
```
