[Java] MP3 to WAV compression

[Nallown]

Hey guys I was just wondering if you had a way of compressing MP3 to WAV in java as I'm trying to play a MP3 track in java. I'm currently using the JLayer library which works PERFECTLY fine in windows but it doesn't appear to be supported in linux. so is there some sort of way to compress MP3 into WAV in java to play the tracks? I don't want to manually compress them as the compression ratio is to high, when compressing it manually the filesize increase by around 90% which will obviously make the JAR to big. I'd consider myself to be a intermediate programmer so feel free to get a little overboard and use advanced methods as I more then likely might be able to understand them, this doesn't mean that I'll be understanding everything so do expect me to ask "what does this mean".

I found this here it was the awnser. I don't program Java myself but i hope it helped!

that makes use of JLayer which I'm currently using and what I'm looking for an alternative which does not really make use of any sort of libraries other then the stock JRE libraries since JLayer isn't supported by linux at least it doesn't work with linux
