Mandatory dependencies:

Numerical Python (http://numpy.scipy.org)

Optional dependencies:

PyFFTW3 (https://launchpad.net/pyfftw) will greatly speed up the NSGT transformation if fftw3 is installed on your system

pysndfile (https://pypi.org/project/pysndfile) is recommended for using the built-in audio import/streaming functionality (otherwise ffmpeg would be tried)

Installation:

In the console (terminal application) change to the folder containing this readme.txt file.

To build the package run the following command: python setup.py build

To install the package (with administrator rights): sudo python setup.py install

Todo:

• Quality measurement for coefficients of sliced transform
• Unify nsgfwin sliced/non-sliced
