A Matlab/Octave fitting tool is available that performs offline=20 processing of .wav files using openMHA, several audiogram-based=20 prescription rules are available and own own can be implemented in=20 Matlab/Octave. https://github.com/HoerTech-gGmbH/openMHA/blob/master/mha/tools/mfiles/mh= agui_fitting_offline.m In terms of commercial gain prescription rules, openMHA supports NAL-NL2=20 and DSL v5 See https://github.com/HoerTech-gGmbH/openMHA/blob/master/README_NALNL2.md https://github.com/HoerTech-gGmbH/openMHA/blob/master/README_DSLmio5.md for details.
