OT: Increasing the volume in a movie clip

[Ryno Swart]

For years I have had a movie clip of birdsong in Venice. It is  
exquisite, crisp and clear, but very faint. Is there some way I can  
raise the volume? I have iMovie, and assorted audio shareware, but I  
cannot make it happen. I know that a number of revolutionaries are  
working with sound, and I would appreciate any help.
