How to Edit PowerPoint Narrations

PowerPoint narrations often require much more editing than text or pictures because sound quality may vary for many reasons, such as the hardware, unwanted noises, lack of familiarity with the equipment, clearing your throat, your state of health, the emotional content you wish to provide, etc. Fortunately it is not usually necessary to redo the entire set of slides, or even an entire slide. There exists a nifty utility named "Sound Recorder" that you can find along the path Programs > Accessories > MultiMedia > Sound Recorder .

You edit a sound file as follows:

• Invoke Sound Recorder using the above path
• Click on File > Open and locate the ".wav" file associated with the slide. Note: when you use RealAudio to create narration it creates a set of numbered slides of the form slide1.pptnnn.wav. Here is the menu that appears:

  
  

• Play the file by clicking on the black right-pointing triangle at the bottom -- if you get the wrong file try the next or previous "nnn" number.
• Stop the playback at any time by clicking the rectangle to the right of the triangle.
• At this point, you can click on Edit > Delete Before Current Position or after the current position. Then if you click on the red circle you can begin your narration. Thus you can either record the entire slide or portions that go before or after a chosen point.
• Then click on File > Save to save the edited .wav file.
