Matlab code for time-frequency fading (TFF)
TFF: Time Frequency Fading
TFF is a toolbox written in Matlab that allows to do time-frequency region filtering out. More precisely, it is a Matlab implementation of the algorithms from Time-frequency fading algorithms based on Gabor multipliers, by, A. Marina Krémé, Valentin Emiya, Caroline Chaux, and Bruno Torrésani, 2020.

Installation
Download the folder "tff2020" into the directory of your choice. Then within MATLAB go to file >> Set path... and add the directory containing "tff2020/matlab" to the list (if it isn't already).
Dependencies
This toolbox requires The Large Time Frequency Analysis Toolbox (LTFAT) which can be downloaded at https://ltfat.github.io
Usage
See the documentation.
