Class F0Tracker

java.lang.Object

marytts.signalproc.analysis.F0Tracker

Direct Known Subclasses:

F0TrackerAutocorrelationDP

public abstract class F0Tracker
extends Object

Author:

Marc Schröder A common basis for F0 tracking algorithms. The following main steps are assumed: 1. preprocessing of the signal 2. estimation of candidates for F0 3. selection of a path through the candidates 4. post-processing of the F0 contour
