Class Mp3InputStream

java.lang.Object
de.pottgames.tuningfork.decoder.Mp3InputStream
All Implemented Interfaces:
AudioStream, Closeable, AutoCloseable
public class Mp3InputStream extends Object implements AudioStream
An AudioStream that decodes mp3. TuningFork doesn't officially support the mp3 file format, use at your own risk. This implementation is as open as it can be, you should be able to extend it easily and make changes and improvements to your needs.
