Step 1: Set Up Your Project Directory

ISlide sld = pres.getSlides().get_Item(0);
FileInputStream fstr = new FileInputStream(dataDir + "sampleaudio.wav");

Step 4: Add Audio Frame

Add the audio frame to the slide.

IAudioFrame audioFrame = sld.getShapes().addAudioFrameEmbedded(50, 150, 100, 100, fstr);

Step 5: Set Audio Properties

Set properties such as play across slides, rewind audio, play mode, and volume.

audioFrame.setPlayAcrossSlides(true);
audioFrame.setRewindAudio(true);
audioFrame.setPlayMode(AudioPlayModePreset.Auto);
audioFrame.setVolume(AudioVolumeMode.Loud);

Step 6: Save the Presentation
