Audio adjustment on a .mov file

This is a really simple job for someone who knows what they are doing. I have created a 3.5 minute video in imovie from clips of different movie files. I have the editing done, but the audio quality is quite different between all the different clips. I need the sound quality normalised, so it all sounds uniform. Please also reduce ambient noise if possible. The final movie will be used on youtube and on websites so needs to play well through speakers and headphones. I can provide the .m4v file and the imovie file if required. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
