Hey all
Some of you may know that audio books are generally recorded at a much lower volume than music, dunno why, but it's really beginning to annoy me because there's a cap on how much I can increase the volume on my mp3 player.
Result: I can't hear most of my audiobooks near heavy traffic or on railway stations, some of it I even have to be somewhere with complete, or near complete silence.

So I was wondering if any of you knew a good (free) windows program you can adjust mulitple mp3-files with? (I've seen audiobooks split up in up to 1200 files).
Maybe some of those mp3-splitter/joiners on tucows can do stuff like that, but I can't see it from the description (it would be nice to have a program that could do both). Tucows audiosection

Hope you can help, and thank you for your time

NB

PS: I won't be near a computer until next weekend, so I won't be able to answer until then.
