[steffendasenbrock]

This post offers a quick introduction into the usage of openMHA. In this example a gain is applied to an audio signal. This is covered in section 3 of the Getting Started Document (displayed below) which you can also download under the following link:

If you have questions about this part feel free to post them here. For other topics regarding the Getting Started document find the corresponding post to that specific section.

UPDATE 08-12-2020:
I used Wayback Machine to download a version of Jack2 (0.3.13.10) from July 2020.
With this version, I no longer experience this problem, so this is a temporary workaround.

Hi!

I have followed the starting guide (http://www.openmha.org/docs/openMHA_starting_guide.pdf) and have installed openMHA via the installation from Windows on https://github.com/HoerTech-gGmbH/openM ... LLATION.md. I have MATLAB 2020b installed too, and I’ve installed JACK2 via the 32-bit Windows installer on https://jackaudio.org/downloads/.


I have problems connecting Jack to openMHA. I’m following the example “4.2 Starting openMHA with JACK Input/Output”. It is possible to start a Jack session, and there doesn’t seem to be any errors (see attached jackstatus.png).


The Jack-server is connected fine – I can connect a mic input to an output and hear it in.
And now for my error. When I try to read a config-file, I get “Unable to load library “MHAIOJackdb”, see cmd_prompt.png attached. I can see that the MHAIOJackdb.dll file is located in C:\Program Files\openMHA\bin.

I've been trying to figure out how to move forward, but I have not been able to find any solution, nor has anyone who has used openMHA that I know experienced this. I hope you'll be able to help me swiftly, as I'm under a bit of time pressure.

Thank you so much in advance!
