I used Free DVD MP3 Ripper to extract an audio file as an mp3 from a DVD. However, I have to raise the volume all the way up just to hear it at a normal volume. What software can I use to adjust the volume level of an audio file so that I don't have to raise the volume all the way just to hear it at a normal level? I have Nero Ultra 7, is there something in there I can use? If so, how do I do this? Thanks.
