An audio file can be added to a slide and played during a slide show. Audio files can be music, voice narration, or sound bites. To record and hear any audio, the computer must be equipped with a sound card, microphone, and speakers. Typical audio file formats include .mp4, .mp3, .wav, and .wma files. To insert a multimedia file (audio, video or screenshot), click the Media button on the Insert tab.
When a sound file is inserted, a sound icon 
is added to the slide and the Audio Tools contextual tab appears to provide options to format how the audio plays on a slide.
After the audio file is inserted, and a sound icon appears on a slide, several formatting decisions should be addressed regarding how the audio sounds during playback. The sound can be previewed by clicking the Play/Pause button in the Audio Control Bar.
The Audio Timeline can be dragged to the left or right to advance the audio to the desired start location. If hiding the icon from displaying on screen during Slide Show View is desired, clear the Hide During Show checkbox in the Audio Options group. If the audio file is hidden during playback, the Start drop-down list selection should be set to Automatically, since the On Click option is only available if the icon is visible so it can be clicked. The Play Across Slides option is great is the file is long enough to play as background music for many slides. This is a popular choice to complement photo albums.
Adding and Modifying Video
Video is even more engaging than video because it adds visual appeal in addition to audio sensory stimulation. An appropriate video can provide a lasting memory for the audience, and provide compelling evidence to influence and educate. Videos offer a lot of upside, but they require also require a lot of resources and careful consideration. The overall length of the presentation needs to be considered when deciding to utilize videos with a slide presentation. Videos tend to be lengthy and the presentation should stay focused and on time. Additionally, video file sizes are enormous. Therefore, storage and portability are often major issues to consider if embedding videos into a presentation.
There are a couple of ways to add video to a PowerPoint presentation. You can add a video from your hard drive, embed one from YouTube, or simply linking an image to the video’s location. Inserting a video is very a similar process to inserting an audio file. When clicking the Video drop-down list, decide between inserting a Video on My PC… or Online Video… Either option will open a dialog window to allow the user to navigate to the location of the video file. Like audio files, many media files are available to download royalty-free from online sites like freemusicarchive.org or videvo.net.
To insert a link to a YouTube site, or embed a YouTube video code, choose the Online Video… option. The link to YouTube option will require a strong Internet connection during playback, however this will control the size of the PowerPoint file.
Once inserted, ensure that the video is moved and resized to be legible for the audience during playback. With the video object selected, a new contextual Video Tools tab will appear with Formatting and Playback options. The Playback tab offers many ways to customize the impact of the video.
The first, and most important decision, is to decide whether the video should play Automatically once the slide appears or until a mouse click triggers the playback. A lot of time can be taken to trim and adjust the fade of a video, which can be useful to ensure a snippet of a video plays instead of the entire video file, which can often be too lengthy. There is no denying the impact of videos in today’s multimedia rich world. Nonetheless, careful planning and design is necessary to ensure that the investment of time and resources are worthwhile for use in a PowerPoint presentation. Some common video and audio file formats are listed below.
Inserting and Modifying Hyperlinks
Hyperlinks make a presentation dynamic by allowing connections to other slides, documents and/or web pages. A hyperlink is an object which when clicked, jumps to another location in the current file or opens another file, or address on the web. Hyperlinks have two parts: the address (of the web page, e-mail address or file location), and the display text (or graphic image). For example, the text: M State, could be linked to the web site www.minnesota.edu. Likewise, the logo 
can also be linked to www.minnesota.edu. To insert a hyperlink, right-click the selected text and choose Hyperlink… from the shortcut menu, or select the text and click the 
button on the Insert tab.
Select a type of link from the Link to sidebar, and then type a label in the Text to display field. A link could open a file on from the Current Folder, a recently Browsed Page from the Internet or a Recent File that was opened on your computer. For web pages, type a URL in the Address: box, or for an E-mail Address, type the e-mail syntax into the E-mail address field. Choose the Place in This Document option to redirect PowerPoint to a designated slide when the link is clicked. For all options, use the ScreenTip… button to add text that displays on-screen when the cursor hovers over the hyperlink. Make sure to test the inserted links by using Slide Show view and clicking each link.
