The Auditory Modelling Toolbox (AMToolbox) is a new Matlab / Octave toolbox for developing and applying auditory perceptual models and in particular binaural models. The philosophy behind the project is that the models should be implemented in a consistent manner, well documented and user-friendly in order to allow students and researchers to actively work with current models and further develop existing ones. In addition to providing the models, it is a goal of the project to collect published human data and denitions of model experiments. This will simplify the verication of models by running the model experiments and comparing the predictions to human data.
