Re: Noisegate level and 'slope' value settings (in context of gain_camfit_compr)

Thanks Tobias. Is it the case that the following code for computing the compression ratios in gainrule_camfit_compr is causing the mismatch, specifically, the index 'end'? max(Lmid+Gmid.(side)(end,:) Perhaps the index could be changed to whichever level corresponds to 65 dB or the level of interest?

Re: Noisegate level and 'slope' value settings (in context of gain_camfit_compr)

Thanks for the clarification, Tobias. It's good to hear that you think our 'noisegate threshold' settings are reasonable. In our case, there is no physical hearing aid and all of the processing is done offline. I've set the 'noisegate slope' to 0 in gainrule_camfit_compr and gainrule_camfit_linear t...

Noisegate level and 'slope' value settings (in context of gain_camfit_compr)

Dear OpenMHA developers, I am wondering whether you could please advise us about the noisegate “slope” settings as defined in the Camfit compressive function. Why is the noisegate “slope” value set to 1 in all bands? Is it defined on the basis of the noise floor in OpenMHA hardware or does this come...
