arrayalloc.h¶

2-, 3- and 4-dimensional array allocation routines with garbage collector class.

fft.cpp¶

Fast Fourier transform, fast multi-resolution Fourier transform, fast cosine transforms and local (lapped) cosine transform.

hs.cpp¶

Structures and routines for harmonic sinusoidal modelling: convex polygonic inharmonicity model, spectral and harmonic spectral peak finding, harmonic sinusoid tracking and harmonic sinusoidal synthesis.

hsedit.cpp¶

Audio editing routines using harmonic sinusoidal model.

hssf.cpp¶

Source-filter repersentation of harmonic sinusoids, including source-filter analysis and synthesis.

matrix.cpp¶
