Any way to increase audio level of your movie?

Question

I've uploaded a taped video into iMovie and when I play it back, the volume level is too low (I can hear it but it's not loud). I've increased the system pref vol, the vol level, and the volume level in iMovie so everything has been turned all the way up.
I saw where you can extract the audio. What can you do with it when you extract it? Incresase it? And if you can increase it, how would you add the audio back to the movie?
What I want to know is, is there another way to increase the volume if you've turned up all the computer volume controls and it's too low?

Answer 1

The best place to increase / adjust audio levels assuming the source video footage has something to work with is in the video editing app. Have you tried posting this question to the iMovie forum?
If your iMovie has low audio levels to start with then this will also be reflected w/in iDVD if no adjustments are made beforehand. Hope this makes sense.
Also check in the iMovie Help Menu if you haven't already:
I can't hear the audio in my movie
If you can't hear some or all of the audio in your movie, here are some things you can check:
Make sure your computer's volume is turned up. Use the speaker controls on your keyboard or the volume slider in the menu bar.
Use the volume slider below the iMovie monitor to increase the movie volume.
Make sure the audio checkbox is selected for the track you want to hear. The audio checkbox is to the right of each track in the timeline viewer.
If the audio checkbox is selected, then choose View > Show Clip Volume Levels and see if the audio levels for the tracks are set to a level that can be heard.
Making your movie louder or softer
If you find that all or part of your movie is too loud or too soft, you can adjust the volume of your movie in the timeline viewer. You can increase or decrease the volume of the entire movie or just specific audio clips. For example, at a certain point in a video you might dramatically increase or decrease the volume of accompanying music.
IMPORTANT: These instructions are for setting the volume of video that people will hear as they play your movie. If you only want to adjust the volume of your computer's speakers, see "Adjusting the volume of your computer in iMovie HD" below.
To make your movie louder or softer:
Click the Timeline Viewer button (shown above).
Select the clip or clips whose volume you want to change in the timeline viewer.
Tip: To learn how to select multiple clips, see "Selecting clips" below.
Click the clip volume button (shown below), and then drag the slider to adjust the volume.
Tip: You can also type a new percentage in the field next to the clip volume button to adjust volume.
You can also make finer audio adjustments within a clip. For more information, see "Fading audio up or down."
