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
F0TrackerAutocorrelationHeuristic: An autocorrelation based
f0 analysis algorithm extended with heuristic post-processing to reduce
voiced/unvoiced errors and f0 doubling/halving problems.
Sinusoidal analysis/synthesis framework supporting various approaches:
Conventional sinusoidal analysis/modification/synthesis
Harmonic plus Noise Model (HNM) based analysis/modification/synthesis
Multiresolution sinusoidal analysis/modification/snythesis
Warning: This is a very basic implementation and it does not work properly!
Sines+transients+noise based analysis/modification/synthesis
