Class MP3Properties

java.lang.Object
  de.vdheide.mp3.MP3Properties

public class MP3Properties

extends java.lang.Object

This class reads properties like bit rate etc. from an MP3 file. Of course these properties are read only... It supports ID3v2, i.e. it reliably skips even files which tags do not use the unsynchronization scheme Illegal entries are marked with special return values, not with exceptions. This enables the class to continue reading other properties.
