marytts.signalproc.sinusoidal.MultiresolutionSinusoidalAnalyzer

public class MultiresolutionSinusoidalAnalyzer
extends BaseSinusoidalAnalyzer

A basic multi-resolution version of the sinusoidal analyzer. The idea is to adjust time-frequency resolution to resolve sinusoids better using a wavelet transform like approach. For this purpose, the original signal is subband filtered and sinusoidal parameters are extracted from the subbands using different window and skip sizes. This class has not been tested sufficiently and the subband decomposition procedure does not seem to be appropriate for this kind of analysis.
