I want to obtain the bitrate of an mp3 file. I can't find anything suitable in the JMF or java.sound APIs.

As far as I can see you are only able to define your own formats, not read what format a certain file has, and this is exactly what I need to do.

Is there any work around for this?

(When this problem is solved I want to write a program that converts all my mp3's to the same bitrate)
