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...

Re: edit openMHA code and get private variables
Two possibilities:
1. Use a debugger, set breakpoints, display the variables you are interested in.
2. Hack the source code to export the data that you are interested in in some suitable form, recompile.
It's all open source after all.

Re: edit openMHA code and get private variables
Not every C++ variable that you find in the source code of the plugins is exported to the configuration tree, and therefore not every C++ variable is accessible from Matlab. You can find the accessible configuration variables for each plugin in the plugin manual, http://www.openmha.org/docs/openMHA_...

Yes the conversion to dB is done by MHASignal::pa22dbspl.

Re: Questions about time constants in dynamic compressor dc
Computation of level from signal in openMHA does not need to know the peaklevel that you configured in plugin transducers. To understand how the level computation from STFT spectra works in openMHA, you need to be aware of two openMHA properties: 1) Central calibration. Because hearing aid signal pr...
