marytts.signalproc.analysis.LpcAnalyser.LpCoeffs

Packages that use LpcAnalyser.LpCoeffs

Package	Description
marytts.signalproc.analysis	A collection of analysis algorithms for signal processing. Important classes are as follows: LpcAnalyser: Linear prediction analysis using autocorrelation appraoch and Durbin recursion LsfAnalyser: Computation of line spectral frequencies (LSFs, or line spectral pairs - LSPs) based on LpcAnalyser EnergyAnalyser: Energy contour estimation with voice activity detection support F0TrackerAutocorrelationHeuristic: An autocorrelation based f0 analysis algorithm extended with heuristic post-processing to reduce voiced/unvoiced errors and f0 doubling/halving problems.
