how to increase recorded sound louder then full volume

Hi

In Your case there are two ways to do this - inside iMovie HD6 or outside it and
via an audio-editing program as Audacity (free on internet)

a. In iMovie
• First You turn on the "rubberband" audio level trimming tool
Here You can increase audio to 150%
• If You need more - then select the Video-clip and go up to advance and "Extract audio"
This doesn't extract BUT place an audio copy on the track under the video-clip and
then silencing the audio in the Video-Track
Now increase the audio in the new Audio-Clip to 150% and so the audio in the Video-Clip

Sum - You now got an 300% increase.

Need more then select the new Audio-Clip and Copy then PAST it - Every Past will
increase audio with 150%.

YES - You Can stack as many Audio-Clips ontop of each other in ONE audio track and
there by increase audio till speakers popps !

b. Outside iMovie.
• Select Video-Clip
• Go to Export - And as QuickTime Expert
• Here select Audio Only as .aiff and Only selected Clip/s
• Close iMovie and open any Audio editor eg Audacity
• Amplify as needed
• Save out as a new .aiff audio file
• Import this into iMovie and put it under the Video-Clip
