Re: distortion of interaural phase/time difference in openMHA output

Hi, I assume that the differnces in the ITDs for angles larger than 30° are caused by the amplification and its effect on the results of xcorr. The gaintable used in that example is not symmetric for left and right channels and it has a compressive characteristic. This yields direction-dependent dif...

Re: Compiling new self-developed plug-ins for PHL

We have started to prepare the PHL for compilation of plugins on the device, but the manual is not yet finished and the software may not be complete, yet. At least the required dev packages are available on the latest Mahalia image available under http://mahalia.openmha.org/ We will work on this in ...

Re: Serving React App with node-red

Hello, for Node-Red example I can only tell that the webserver comes with the Node-Red installation, so we didn't have to set up much in that regard. From here it seems that it is somehow possible by using the uibuilder node to use it for React. For transferring files to the PHL you can use the scp ...

Re: equalize plugin

Documentation of the equalize plugin is found in the plugin documentation: http://www.openmha.org/docs/openMHA_plugins.pdf#subsection.9.1 In a nutshell, a vector needs to be provided that contains a linear gain value for each fft bin. The fft bins / frequency range depend on sampling rate and paramt...

Re: Error using mhactl_wrapper>mhactl_wrapper_2 (line 64)

For a quick test I have upgraded jack on my macOS Catalina from the 1.9.19 homebrew installation to 1.9.20 using the jackOSX installer. Afterwards I was not able to start the jack server. I did not dig into the problem and this does not explain your issue as the jack server seems to work on your sys...

Re: Error using mhactl_wrapper>mhactl_wrapper_2 (line 64)

Hello!
Regarding the jack issue: The jack library is not found at the expected location. How did you install openMHA?

Is your working directory ...examples/01-dynamic-compression when you try to load the dynamiccompressor configuration file?

Re: ?read:.. command starts automatically

Hello, that behavior could be caused by the Node-Red GUI made for the generic-hearing-aid configuration which might be still running on your system. It periodically sends the start command to mha to activate the processing after finishing the load process of the GUI. Ssh into the system and execute ...
