Tools for auditory research

The present pages include a few Matlab tools for psychological research. MLP (Grassi & Soranzo, 2009) is a Matlab toolbox that has been developed to implement the maximum likelihood threshold estimation for auditory research (Green, 1990, 1993). The toolbox is a ready-to-use tool that enables the user to estimate sensory threshold in several, classic, built-in auditory experiment.

PSYCHOACOUSTICS (Soranzo & Grassi, 2014) is the follow-up of MLP and extends the toolbox to two classic non parametric adaptive procedures, namely: staircase (Levitt, 1971) and PEST (Taylor & Creelman, 1967).

The third tool is a set of scripts, functions and programs that accompany a book we wrote to introduce students to the Matlab programming language (Borgo, Soranzo, & Grassi, 2012). In those pages you can find the codes of some of the codes that are written in the book.
