A Matlab/GNU Octave toolbox for phase (signal) reconstruction from the short-time Fourier transform (STFT) magnitude is presented. The toolbox provides an implementation of various, conceptually different algorithms ranging from the well known Griffin-Lim algorithm and its derivatives to the very recent ones. The list includes real-time capable algorithms which are also implemented in real-time audio demos running directly in Matlab/GNU Octave. The toolbox is well-documented, open-source and it is available under the GPL3 license. In this paper, we give an overview of the algorithms contained in the toolbox and discuss their properties.
