Package com.softsynth.jmsl.util

Class Oof

java.lang.Object
com.softsynth.jmsl.util.Oof
All Implemented Interfaces:
SequenceGenerator
public class Oof
extends java.lang.Object
implements SequenceGenerator
One over F distribution after R.F. Voss's algorithm, taken from Dodge/Jerse "Computer Music", Schirmer Books, page 290, translated from the Fortran

Each object maintains its own last value and random driver, so all you have to do is call next() on your Oof object to generate a 1/f sequence.

    • Oof

      public Oof​(int numBits)
      Constructor, specify number of bits in desired output range
      ex. 4 gives a range of 0..15
      ex. 8 gives a range 0..255

      Initial random seed saved for reset()

  • Method Details

    • next

      public int next()
      Description copied from interface: SequenceGenerator
      Return next value in sequence, then generate a new one.
      Specified by:
      next in interface SequenceGenerator
      Returns:
      next value in 1/F sequence

    • getNext

      public int getNext()
      Specified by:
      getNext in interface SequenceGenerator
      Returns:
      next without changing current state

    • setNext

      public void setNext​(int next)
      UNIMPLEMENTED Set next value in sequence. UNIMPLEMENTED
      Specified by:
      setNext in interface SequenceGenerator

    • setSeed

      public void setSeed​(int seed)
      Set pseudo-random generator seed for repeatable sequences. Saves new seed for reset();
      Specified by:
      setSeed in interface SequenceGenerator

    • getSeed

      public int getSeed()
      Specified by:
      getSeed in interface SequenceGenerator
      Returns:
      seed set by setSeed.

    • randomize

      public void randomize()
      Set seed from system time. This will result in a unique sequence each time it is called. Also saves the seed for reset()
      Specified by:
      randomize in interface SequenceGenerator

    • reset

      public void reset()
      Reset sequence generator so that it will restart at last saved seed value.
      Specified by:
      reset in interface SequenceGenerator

    • main

      public static void main​(java.lang.String[] args)
