Record Sound Directly onto PowerPoint Slides in Office 2011 for Mac
If you don’t have a prerecorded clip to use in your PowerPoint slide show and have to create your own audio, you can record a sound directly onto a slide in PowerPoint 2011 for Mac by following these steps:
Click the Ribbon’s Home tab, and in the Insert group, choose Media→Record Audio to display the Record Sound dialog.
Choose a device from the Sound Input Device pop-up menu.
This menu displays input devices currently connected to your computer, such as an internal microphone. You add and remove devices in the Mac OS X Sound control panel.
Thereafter, choose a source from the Input Source pop-up menu.
The reason why you need to go through second step is because some sound input devices may have more than one input source.
To record a sound, click the Record button at the top of the dialog.
Click Stop or Pause when you’re done and then click Play to preview your recording.
Type a name for your sound file in the Name text box.
The name can be used to help you when choosing animation settings and in VBA.
When you're done recording your sound, click Save to produce a sound icon on your slide.
If you need greater control over audio recordings for PowerPoint slides, check out GarageBand, a robust sound-editing application from Apple. With GarageBand, you can record your narrations straight into the program and save them as sound files, which you then insert into PowerPoint. Garage Band comes with many Macs. Look for GarageBand in your Applications folder, or purchase iLife.
