extends javax.sound.sampled.AudioFileFormat

This class specifies the AudioFileFormat of a REX file. The following properties are accesible via the getProperty()-method if they could be found in the file:
- duration: The duration of this file in microseconds (Long)
- author (optional): name, email and URL of the author (String)
- copyright (optional): a string containing the copyright information (String)
- comment (optional): a free text (String)
- slice_count: The number of slices found in this file (Integer)
- bpm: The Tempo of the file (Float)
- time_signature: An int-Array containing the nominator of the time signature at position [0] and the denominator at position [1] (int[])
- slices: A two-dimensional int-Array which contains information about the slices in this file. Sor each slice there is one entry in the first dimension two entries in the second dimension describing the position and the length of the slice in sample frames. For example the position of the third slice can be found at slices[2][0] and the duration of the first slice at slices[0][1].
