All Implemented Interfaces:

FilterBankAnalyser

public class ComplementaryFilterBankAnalyser
extends FilterBankAnalyserBase

This class implements the complementary filter bank used in [Levine, et. al., 1999] for multiresolution sinusoidal modeling. The filter bank consists of a collection of filter channels (See ComplementaryFilterChannel.java for details). [Levine, et. al., 1999] Levine, S. N., Verma, T. S., and Smith III, J. O., "Multiresolution sinusoidal modeling for wideband audio with modifications", in Proc. of the IEEE ICASSP 1998, Volume 6, Issue , 12-15 May 1998, pp. 3585-3588.
