I remembered that incorrectly. But see lines 11-28 in that file for how to initialize these structures with a few lines of Matlab/Octave code.

Re: Initialize sAud and sFitmodel in matlab?

There are functions to create and modify these structures in https://github.com/HoerTech-gGmbH/openMHA/tree/master/mha/tools/mfiles/libfuncs. The functions there get combined into libraries (files starting with "lib" in https://github.com/HoerTech-gGmbH/openMHA/tree/master/mha/tools/mfiles...

How does one switch between different fittings.
By clicking on the respective lines in the "Presets" box.
How does on adjust a fitting?
By changing the frequency-specific gains with the fine-tuning controls at the bottom of the GUI.

Hope this helps!

Re: How to start openMHA

But I want to check the variables and now I compiled the openMHA. Please explain what you mean by "check the variables" in more detail. Maybe there is an easier way to achieve what you want. The compilation instructions in COMPILATION.md are intended for developers. there is no place to r...

Re: Steps after audiogram entry

There is a fitting GUI manual at http://www.openmha.org/ documentation.

Re: Question regarding target REIGs in openMHA

No, this is not a feature of this GUI. In order to access all insertion gains, you would have to extract (with mha_get()) the gtdata matrix from the MHA dc plugin that you have just fitted.

Re: Question regarding target REIGs in openMHA

Your graphs for 20dB pantonal hearing loss show amplification for frequencies above 500Hz. Please refer to the openMHA Fitting GUI manual for an explanation of the display. I hope this helps, please ask follow-up questions here if anything remains unclear so that we can improve the documentation.

Re: dynamic compressor question

Each entry in the shapes matrix is a weight factor with which each STFT bin is mapped to each band. For rectangular filters, you will see mostly ones and zeros. I suggest plotting the shapes with Matlab or octave to inspect the shapes: mesh(mha_get(mhahandle,'path.to.fftfilterbank.shapes')) (Adapt p...
