Using the measure_response.m Matlab code to calibrate my PHL I see that one is trying to achieve a 80dB SPL reading using a sound level meter. The input to the speaker is produced using the sine plugin to produce input to the speaker. The levels are RMS in dB SPL FF. The sine levels are negative. So...

Thanks, That was very helpful.

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?
