marytts.signalproc.process.SimpleNoiseRemover

All Implemented Interfaces:

InlineDataProcessor

public class SimpleNoiseRemover
extends PolarFrequencyProcessor

Author:

Marc Schröder A simple implementation of a separator of periodic and aperiodic components, based on an attenuation function for signals below a given threshold. This class provides the periodic (voiced) components, as the exact complement of @see SimpleNoiseKeeper.
