Class SaxelChunk

java.lang.Object
  edu.harvard.hul.ois.jhove.module.iff.Chunk
      edu.harvard.hul.ois.jhove.module.aiff.SaxelChunk

public class SaxelChunk
extends Chunk

Implementation of the AIFF Saxel (Sound Accelerator) Chunk. The Saxel chunk has only a tentative and incomplete status in the AIFF-C draft of 1991, and apparently nothing further was ever done with it. For purposes of extracting parameters, we treat the description of the SaxelChunk and Saxels as valid, while regarding the SaxelData as opaque.
