You can't. You need an audio-editing software.
To change the audio in the Audio/Music track, simply delete it and put something else in its place. To change the audio of a video in the video track, first Mute the audio of the video. Then place alternate audio in the Audio/Music track.
First you have to mute the video's audio in Windows Movie Maker. Once the audio portion of the Video is muted, you can import and drop the desired audio you want to use into the Audio/Music track.
The way to remove the video from the audio (and only retain the audio) is by dragging the video clip to the MUSIC/AUDIOtrack in the Time-line view of Windows Movie Maker instead of the Video track.Once you have the audio there, publish/finish it. That will change the video to an 'audio' format (in this case a .wma).
You go to the watch video toolbar and let it drop and then you can adjust the time of the video
MP3- audio MP4- audio and video MP5- audio, video
You can save the audio from a video using Windows Movie Maker.In Windows Movie Maker, you can delete the video and only keep the audio by following these instructions:> Import your video into Windows Movie Maker> Change to Time-line view> Click the + button beside the Video track> Click, hold and drag the audio track down into the Audio/Music track below it> Now right-click on the video in the Video track and delete/cut/remove itAll that should be remaining is the audio (from your original video) which is now in the Audio/Music track. If you choose to Publish/Finish this audio-only file, its format will automatically be converted into a .wma file following the process.
Well, you can click edit video and change the speed. You will have to do a voice over since, the audio is in the video.
Pull the audio off the video that's on YouTube, or try Limewire for just the audio file.

There is only one audio track to work with in Windows Movie Maker. The only other audio track is connected to the Video Track (the video's audio).Therefore, you can only have one video (with audio) in the Video Track and one audio/music insertion in the Music/Audio Track.
