What is the best way to normalize & compress voice audio files?
I have a bunch of regular audio CDs that have voice narration with some music in the background. My goal it to put these all onto other CDs as MP3s so I can play them in my RIO MP3 CD player.
My problem is that the amplitude of the narrator's voice is so great that at times your ears are being blasted away and other times he is too quiet to understand. During the WAV to MP3 conversion process, I would like to normalize & compress the audio so that the tracks are all about the same level and that the guys voice is always close to the same level.
What would be the quickest, most efficient way of doing this while still having a good quality product?
