So you are saying basically that writeaccess allows for the filter state to remain the same (which is desirable in my case), and valuechanged will reset its state after each update? No, this is not what I meant to say. Sorry for not being clear enough. If the initial state is filter=no, then your u...

I will share a bit of my code and I invite any recommendation as how to best approach this. I understand that you are in the process of modifying your code to add a runtime configuration class to your plugin, because you want to switch processing on and off during runtime with a boolean switch. And...

1a) I have written a plugin already with a single interface class, and now I would like to be able to update some of the algorithm's parameters at runtime. How do I know what should stay in that class and what should be moved to the runtime config class? You do not actually move the parameters, but...

You need an interface class (which implements the interface functions prepare(), release(), process(), constructor(),...) in every plugin. Whether you should use an additional runtime configuration class or not is the question. Advantages of using runtime configuration classes: You can allow configu...

Yes, this piece of documention is somewhat hard to find. http://www.openmha.org/docs/openMHA_developer_manual.pdf section 2.2.1.1 last paragraph should explain the idea. See it applied like you need it here: https://github.com/HoerTech-gGmbH/openMHA/blob/master/mha/plugins/wave2spec/wave2spec.cpp#L1...

peaklevels are assigned in plugin transducers. wavrec is a separate plugin and has no knowledge of the peaklevels configured there. wavrec documentation is minimalistic. It says "wav file recorder". wavrec stores the audio samples on disk as they are processed inside MHA, without any scali...

Floating point data representations as used in computers have limited accuracy. Not all decimal numbers can be stored with their exact value in a floating point data type on a computer. The numbers are rounded to the nearest value that can be represented. 0.99 for example cannot be represented exact...

Update: The fix will be part of the next openMHA release. You can test and use it before we make the next release by replacing mfile mha_findid.m in your openMHA installation with this version: https://raw.githubusercontent.com/HoerT ... a_findid.m
