LTFAT Description

LTFAT, short for Linear Time / Frequency Toolbox is designed to be a Matlab / Octave toolbox for executing time-frequency analysis. It is intended both as an educational and computational tool. The toolbox provides the basic Gabor, Wilson and MDCT transform along with routines for constructing windows (filter prototypes) and routines for manipulating coefficients. Main features: TF-transforms: Gabor, Wilson and windowed MDCT Basic Fourier and TF-analysis (unitary DFT, involution, twisted conv., symplectic Fourier transformation). All transforms have methods for generating perfect reconstruction systems. TF-Operators: Gabor multiplier and spreading representation GUI in Matlab to modify signals in the time-frequency domain. Sparse regression in the Gabor and WMDCT domain. Support for full length windows and finite length windows (FIR) Windows: Gauss, Hanning etc. Canonical dual and tight windows Spectrogram and reassigned spectrogram plots Filterbanks. Non-stationary (time-evolving) Gabor systems. Simple tools for working with coefficients (thresholding, N-term approx.) Demos demonstrating the use of the toolbox. Works in Matlab / Octave with a backend in C for greater speed.
