Is there a way to specify iolib = MHAIOFile for the input and iolib = MHAIOalsa for the output.

Essentially I want to listen to a .wav file using mha.

Since the cfg file really defines a data flow graph with connected plugins, is there a tool that will display the graph. This would be very useful in debugging cfg files and in understanding the examples. I am used to coding for FPGAs where compute is done via data flow rather than instruction execu...

Changed mha.algos=[route:sort_input rmslevel gain route:sort_output gain:mute_dummies] to mha.algos=[route:sort_input rmslevel:rd1 gain route:sort_output gain:mute_dummies acmon] in the cfg file, and access the rms vac vars via print("mha.acmon.rd1_level_db:",mha.get_val('mha.acmon.rd1_lev...

I can't seem to get the python code to get a value from rmslevel as a way of debugging cfg files. I am running the following cfg nchannels_in = 8 srate=24000 fragsize=55 iolib=MHAIOalsa io.in.device=hw:0 io.out.device=hw:0 io.priority=90 # MHA library name mhalib = mhachain mha.algos=[route:sort_inp...

I wrote a python code that uses mha.get_val() via 10.0.0.1:33337 on my Mac.

Thanks for your help. I will try it. BTW..How do you see the rmslevel output? In the log?

I am trying to convert the example 01-dynamic-compression to use headset and stereo mic and alsa for a PHL device. So I have to sort the input & output. I have made changes to include sort in a list of algos. I can run mha interactively on that cfg file but I get nothing. in headset or BTEs. I t...

Where is the fitting passed to the PHL? Where in mha is the fitting received?

I have a preset created via MatLab fitting GUI. I select it and have compression enabled and I can tell that it is being used by the PHL. I would like to understand the mechanism for passing the preset gains etc, into the device. Where does mha pick it up? It must be stored somewhere since it appear...

Yes!

I think that this would work.

I would like to update the examples to run on PHL as well as other devices.
I think this approach is workable.

Thanks.
