ProcessBuilder does not stop

Question

I am trying to decode an mp3 file to a wav file by using the ProcessBuilder class under Linux. For some reason the process does not stop so that I have to cancel it manually

Answer 1

It might be a lot easier for you to use a LAME Java wrapper like LAMEOnJ. That way you avoid spawning off processes and you can just interact with lame as if it were a Java library.
