Structure of the toolbox

The HUTear toolkit is a modular package which contains a generic frame for an auditory model and a set of modules which can be hooked into it to produce a model for some particular application. The basic building blocks of such a model are shown in Fig. .

The name of the frame function is AudMod, which is used in the following way:

>> A=AudMod(signal,profile);

where signal is a single row or column vector of signal samples. profile is is either a struct variable or a name of a text file where a struct variable is defined. The output A is a matrix of output row vectors. The number of output channels is specified in profile description. It is the same as the number of channels in the filterbank. Using only one, e.g., gammatone filter, the model is reduced to a single channel model. A user may design a new model profile or use some of the ready-made profiles, (see below.)
