PhaseReT is a Matlab/GNU Octave toolbox collecting implementations of phase-reconstruction algorithms for complex time-frequency representations (like STFT).
The toolbox depends on LTFAT - Large Time-Frequency Analysis Toolbox.
Further, some functions require additional dependencies:
In order to use the toolbox it is necessary to run
phaseretstart;
from the [path_to_phaseret] directory. The command checks whether LTFAT has already been started and whether MEX interfaces are already compiled.
If you are using the pre-compiled Windows package, the next step is not necessary.
The mex interfaces can be compiled by running
phaseretmex;
from within Matlab/Octave command line. Note that
the FFTW library has to be installed
by e.g. apt-get install libfftw3-dev on Debian-based systems.
On Windows, this has to be done manually by downloading the archive from here and placing
libfftw3-3.dll and libfftw3f-3.dll to the [path_to_phaseret]/mex subdirectory).
To start the toolbox automatically add the following lines
addpath(path_to_ltfat);
addpath(path_to_phaseret);
ltfatstart;
phaseretstart;
to your startup script Matlab Octave.
Note that pre-compiled packages for Windows can be downloaded from the GitHub release page.
Online documentation is available here.
