Parameters:

annotations -

applySteadyStateFilter

public void applySteadyStateFilter(double maxCentsDifference,
                                   double minDuration)

applyPitchClassFilter

public void applyPitchClassFilter(double[] pitchClasses,
                                  double maxCentsDifference)

applyWaveletCompressionFilter

steadyStateAnnotationFilter

public void steadyStateAnnotationFilter(java.util.List<Annotation> annotations,
                                        double maxCentsDifference,
                                        double minDuration)

Steady state filter: only keep annotations that are repeated for x seconds within y cents.

Parameters:

annotations - The list of annotations to filter.

maxCentsDifference - The number of cents the next annotation may differ.

minDuration - The minimum duration of the 'note'.

getAnnotationTree

public AnnotationTree getAnnotationTree()

clear

public void clear()

Remove all annotations from the listeners.

clearTree

public void clearTree()

delegateAddAnnotations

public void delegateAddAnnotations(java.util.List<Annotation> annotations)

Adds a list of annotations to listeners.

Parameters:

annotations - The annotations to add to the listeners.

delegateAddAnnotations

public void delegateAddAnnotations(double startTime,
                                   double stopTime)

Adds annotations to listeners. The annotations are defined by a search on time.

Parameters:

startTime - The start time.

stopTime - The stop time.

delegateAddAnnotations

public void delegateAddAnnotations(double startTime,
                                   double stopTime,

                                   double stopPitch)

Adds annotations to listeners. The annotations are defined by a search on time and pitch.

Parameters:

startTime - The start time.

stopTime - The stop time.

startPitch - The start pitch.

stopPitch - The stop pitch.

delegateAddAnnotations

public void delegateAddAnnotations(double newMinProbability)

alterSelection

alterSelection

public void alterSelection(double newMinProbability)

extractionFinished

public void extractionFinished()

extractionStarted

public void extractionStarted()

getCurrentSelection
