java.lang.Object
  jass.generators.HalfSampleDelayKLFilter
      jass.generators.HalfSampleDelayTubeFilter

All Implemented Interfaces:

Filter

public class HalfSampleDelayTubeFilter
extends HalfSampleDelayKLFilter

A filter corresponding to a tube of a given length and shape. Excitation enters one side ("glottis") and sound is produced at the other end. Besides shape data it needs the glottal reflection coefficient and the total damping factor, modeling losses in the system. This class offers also a higher level interface to set the tube parameters through the TubeShape.
