audio processing using java

We have a requirement where we need to convert from .wav file to .mp3 and we are currently using "Tritonus" library to do that . The concern with that library is  that requires "installation" of some "dll" files to the class path.

I am wondering are there any API's those allow better processing without local installation.
And other question is ,having mp3 format files will make it easier to join the files into a single file than having .wav files ?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am not sure if JLayer is any better, but here is the link if you are interested.

I have not tested this myself.
The javazoom is the best option, but...
