No. There is only one audio track to work with in Windows Movie Maker. You can drag an audio backwards on the time-line to overlap the music... but it may not sound the way it would if it were on two different tracks.
Perhaps you can try to use a streaming audio recorder to record audio on Windows Movie Maker.
No narration feature in Windows Live Movie Maker. Sorry.
You can't do that on Windows Live Movie Maker, but you can extract the audio from a video in Windows Movie Maker v2.6 and save/publish it as an audio file.
No. Windows Movie Maker records in .wma (Windows Media Audio) format. However, you can import and edit .wav files in the program.
Use Windows Movie Maker
You need to use an external audio editor for fixing audio before importing it into the program. Windows Movie Maker can't fix audio (only adjust volume levels/fades).
Speeds faster than 1x does not support audio in Windows Movie Maker.
You can record on Windows Movie Maker by using the Narration feature. (Note: There is no Narration feature in the Windows Live Movie Maker version).
You can't do that with audio on Windows Movie Maker. The application is very basic with limited features/functions. Masking is not a feature that is included.
You have to record the audio first and save it in one of the following audio/music formats used by Windows Movie Make:.aif, .aifc, .aiff, .asf, .au, .mp2, .mp3, .mpa, .snd, .wav, and .wmaOnce the audio is saved/converted to one of the above mentioned formats, you can import it into Windows Movie Maker.
Unfortunately, you can't do that with Windows Live Movie Maker (2011). It is a stripped-down version of Windows Movie Maker with very basic features, and only one audio track to work with. Sorry.
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.
You do not have any other audio publishing options other than .wma if you are editing it in Windows Movie Maker. My suggestion is... edit the audio in Windows Movie Maker; publish/finish it in .wma format; then convert it to .mp3 using an Audio Conversion program.
