The gtde toolbox is a set of MATLAB functions for localizing sound sources from time delay estimates. From the sound recorded on the microphones of any non-coplanar arbitrarily-shaped microphone array, the toolbox can be used to robustly recover the position of the sound source and the time delay estimates associated to it. This piece of software is associated to the paper “A Geometric Approach to Sound Source Localization from Time-Delay Estimates” in IEEE Transactions on Audio Speech and Language Processing.
