A new version of the Auditory Modelling Toolbox has been released. It includes now the models from Dau and Jepsen with an adaptation loop, modulation filterbank and DRNL. The only thing currently missing for these models is the optimal detector, which will be included in the next release.
To install it, you can download it from Sourceforge. You also have to install the latest version of the Linear Time/frequency Toolbox. Then in Matlab or Octave just go to the directories of the toolboxes and run:
>> ltfatstart >> amtstart
Have a look at the demo folder. For example the following code will result in the figure below:
>> demo_audspecgram;
