It works. mic-->MHA-->PD---->MHA2--->spkr in MHA mha_Device.set_val('io.name','MHA') mha_Device.set_val('io.con_in ',' [system:capture_1 system:capture_1]') mha_Device.set_val('io.con_out ',' [pure_data:input_1 pure_data:input_2]') in MHA2 mha_Device.set_val('io.name','MHA2') mha_Device.set_val('io....

I think this is the way to connect.... I am working on a test python code jack_connect MHA:in_1 system:capture_1 jack_connect MHA:in_2 system:capture_2 jack_connect MHA:out_1 pure_data:input_1 jack_connect MHA:out_2 pure_data:input_2 jack_connect pure_data:output_1 MHA2:in_1 jack_connect pure_data:o...

I have two instances of openMHA running. I have jack set via jack_connect MHA:in_1 system:capture_1 jack_connect MHA:in_2 system:capture_2 jack_connect MHA:out_1 system:playback_1 jack_connect MHA:out_2 system:playback_2 jack_connect MHA2:in_1 system:capture_1 jack_connect MHA2:in_2 system:capture_2...

Has anyone used the Pure Data audio processing tool and inserted it into the openMHA audio stream? I want to identify and modify phonemes in the audio stream and use openMHA and its plugins. Pure Data does not exist as a plugin so it would be necessary to route the oudio to PD and then back into the...

I wanted to be able to build from sources. I found that OSC was not what I needed to have installed. Instead configure was really looking for libio which I was able to install. I was able to build the 4.18.0 pkg after building after installing the latest jack2. So all is ok. (I haven't tested it yet...

Has anyone installed 4.18.0 on a Mac? I had difficulty getting LSL, EIGEN, and OSC installed in order to build the 4.18 package. I did finally get LSL and EIGEN installed and found by configure. However OSC installs only via Arduino and cannot be found by configure. Any suggestions? Thanks, Dan Pozn...

I cannot get the addsndfile plugin to work. In my code I set usefile to False and I get mic to play on the earbuds. If I set it to True I do not get an error but I also do not get audio output. Does anyone have a simple example code that demonstrates the addsndfile plugin? Here is a snippet of what ...

I want to input wav file audio that I have captured or created and then process the audio and output to headset. I can't see how to do that since it appears that setting iolib = MHAIOFile, commits to doing file I/O and then can't do headset output. So I asked chatGPT4 how to do it with openMHA and w...

Sorry for slow response....I haven't been monitoring lately.. I have worked with FPGAs in high performance computing and my group developed a compiler and open source quite a number of years ago. I am now interested in hearing aid development and speech intelligibility. I think the traditional proce...

I am trying to create a config that can be modified while system is running. I have a statement with "algos slots" that I attempt to define after starting. mha_Device.set_val('mha.transducers.mhachain.ola.addchain.algos', '[mhachain:add1 mhachain:add2 '+ ' mhachain:add3 mhachain:add4 '+ ' ...
