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

We will release a proper fix ASAP.
A fix for the error that you found was released today in openMHA version 4.13.0.

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

Thank you! You have found an error in our implementation. I think index "end" is used there because Gmid is computed from camfit_linear, and as a linear fitting rule, it supposedly assigns the same gain to all input levels. However, in commit https://github.com/HoerTech-gGmbH/openMHA/commi...

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

As you have seen, our implementation differs from the publication with respect to the noisegate. Another difference that I am aware of is that our implementation does not apply negative gains. If I remember correctly, the method from the publication can prescribe negative gains, e.g. for an audiogra...

Re: Plugins not prepared while trying to load the node red example

This seems to use a self-compiled version of openMHA, branch development. (1) What is the output of "git status"? (2) Does "make test" succeed? (2a) If not, what is the error message?

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

One function of the noise gate is to protect the wearer from perceiving soft "sounds that the person may rather not hear", as Dillon puts it [1]. Another function is a decreased likelihood of feedback for low input levels. Of course it also prevents audibility of the microphone noise. With...

Do I maybe need to install a specific version of JDK?
The Matlab installer always installs a complete JRE inside the Matlab installation directory, as far as I know. You do not need to install Java separately.

Re: Issue with mha_get(mha,'nchannels_in')

Thanks for posting this here. I have investigated this and confirm that you have found a bug in the openMHA Matlab tools. It seems this was introduced earlier this year when we changed some aspects of the network communication. The bug manifests when performing these (or similar) steps: mha.host='lo...
