How to Insert Audio into PowerPoint

Generally, we tend to insert graphics, animation effects, audio frames or video frames into our PPT slides to make it more vivid and persuasive. Adding high-quality audio, background music for example, to a slide presentation can greatly increase the impact that it has on your viewers.

Spire.Presentation for .NET is a comprehensive toolkit which allows developers to process PPT slides in massive ways, including multitude of graphics and multimedia features. In this topic, we will make a simple introduction of how to insert audio into PPT using C#.

Step 1: Create a new PPT document first

            Presentation presentation = new Presentation()

Step 2: Basically, we need to set a background image before inserting Audio file

string ImageFile = "bg.png";

            RectangleF rect = new RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height);
            presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
            presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;

Step 3: Load the Audio file from disk

presentation.Slides[0].Shapes.AppendAudioMedia(Path.GetFullPath("paipai_sound.wav"), new RectangleF(100, 100, 20, 20));

Step 4: Set properties of AutoShape

IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 150, 600, 250));
            shape.ShapeStyle.LineColor.Color = Color.White;
            shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.None;

Step 5: Save PPT file

presentation.SaveToFile("Audio.pptx", FileFormat.Pptx2010);
            System.Diagnostics.Process.Start("Audio.pptx");
