The Large Time-Frequency Toolbox (LTFAT) in Python

Project description

The ltfatpy package is a partial Python port of the Large Time/Frequency Analysis Toolbox (LTFAT), a MATLAB®/Octave toolbox for working with time-frequency analysis and synthesis.

It is intended both as an educational and a computational tool.

The package provides a large number of linear transforms including Gabor transforms along with routines for constructing windows (filter prototypes) and routines for manipulating coefficients.

The original LTFAT Toolbox for MATLAB®/Octave is developed at CAHR, Technical University of Denmark, ARI, Austrian Academy of Sciences and I2M, Aix-Marseille Université.

The Python port is developed at LabEx Archimède, as a LIF (now LIS) and I2M project, Aix-Marseille Université.

This package, as well as the original LTFAT toolbox, is Free software, released under the GNU General Public License (GPLv3).

The latest version of ltfatpy can be downloaded from the following PyPI page.

The documentation is available here.

The development is done in this GitLab project, which provides the git repository managing the source code and where issues can be reported.
