Hi,
I am new to OpenMHA, currently working on NAL-NL2 gain to process the audio.
After some instructions, I can get the gains using NALNL2 Wrapper, but what I got are the gains at 19 different frequency bands. But I am not sure how to use these gains on the audio, is there any example that I can follow?

Additionally, to obtain these gains, I need to invoke the wrapper separately. Is there a method to build the entire process end-to-end? Ideally, I would like to run a single file, provide the audiogram, demographic information, and WAV file, and then have the pipeline export the processed audio.

Thank you!!
Teddy

The offline fitting tool contained in openMHA preprocesses wav files with a dynamic compression prescription rule of your choice. Start it from Matlab or Octave by invoking

mhagui_fitting_offline

It can process multiple wav files at once.

The installation directory of the openMHA mfiles depends on your operating system, see https://github.com/HoerTech-gGmbH/openM ... LLATION.md. Add this directory to your Matlab/Octave path.
