Hi Dan,
you might consider using the homebrew installer, see
https://github.com/HoerTech-gGmbH/openM ... h-homebrew
for details. It should also install all dependencies for compiling openMHA.

Best,

Hi,
we just released a new version of Mahalia (operating system runnign on the PHL) which supports the compilation of single plugins on the PHL. An example that demonstrates this is available in the latest openMHA release 4.18.0.

The Mahalia 4.18.0-r0 disk image is available here .

Dear openMHA users,
the release of openMHA 4.18.0 adds several examples to the software and support for current operating systems. See
the release notes for details.

Hi Dan, iolib = MHAIOJack and the plugin "addsndfile" at the beginning of your processing chain should do what you want. Setting addsndfile.mode = replace will replace the microphone input signals with the content of your .wav file. It seems that chatGPT4 did not read the openMHA plugin ma...

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...

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 ...

Hello, in your configuration the line mha.plugin_name = addsndfile is overwritten three lines below by mha.plugin_name = overlapadd Use of the plugin mhachain can be used to resolve this: mha.plugin_name = mhachain mha.mhachain.algos = [addsndfile overlapadd] ... You'll have to modify the remaining ...

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 ...

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...

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...
