Adding different forms of media to a PowerPoint presentation (PPT) can make it more engaging for your followership, as well as appealing to different types of learning. Although there may be any number of reasons, from adding a voice-over to just add some background music. PowerPoint can add audio clips of different types of files. MP3, WMA, or WAV extension files are the common types that you can fit in PowerPoint slides (PPT). These audios automatically embed into PPT File. Indeed also, it's a good practice to place your audio in the same computer folder or Path in which you save your PPT indeed before you insert them.
