I. WORKING WITH
AUDIO
1. Adjusting
project audio
Your project may have audio on the audio
portion of the video track, and audio on the audio/music
track. You can adjust the balance between these two tracks by
clicking on the Set Audio Levels icon in Storyboard or Timeline
View.
That opens
a slider that you can adjust: 
This adjustment may best be left till
last. 'Sup to you.
2. Adjusting
clip audio
You can adjust the audio of individual clips in
either the audio portion of the video track, or the audio/music
track.
Insert a video clip that has audio. In
Timeline View, click the audio clip in the video portion of the
track. Then, click on Clip from the menu. Then, put the
cursor over Audio to see your options: Mute, Fade In, Fade
Out, Volume (adjust).
You can get to these same four options by
right-clicking and making your selection. Click on the option
to place a check beside it. Click on it again to remove the
check.
3. Narrating
your movie project
You can narrate all or part of you movie.
Click on the Narrate Timeline icon (the microphone)
and you'll be taken to this window:

You'll need to make some setting
choices before you begin. First, check the mic level.
The VU meter (volume unit) should not stay in the red or there may
be distortion. Try to have your peak volume just below the red
area. Click on Show More Options for additional settings.

Time available is the amount of
time you have available to talk before pre-existing audio clip
starts. You can only have one audio clip on the audio/music
track at a time. If you keep talking, it will push an existing
audio clip to the right.
To avoid a problem in this area,
you can click Limit narration to available free space on Audio/Music
track.
Narration will begin where the
play head is placed on the timeline. To begin recording, click
Start Narration.
When you click Stop Narration,
you'll be taken to a dialog box where you name the file you just
recorded. The file will automatically be saved as a .WMA
(Windows Media Audio) file. It will appear in the Audio/Music
track, and you can then manipulate it as you can with any other
file.
