The open Master Hearing Aid Forum

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 '+ ' ...

Does anyone know where the openMHA library was ported to run on FPGAs. Is there a Githib project? Some website? The reference I saw was: "Implementing the open master hearing aid on a system-on-chip field programmable gate array" The Journal of the Acoustical Society of America 148, 2508 (...

I just noticed that the search box is present prior to my logging in.
If I log in the box goes away.

I get the following..

mha [7] ?val:mha.sort_output.mhaconfig_out.srate
(mha_parser) Invalid query mode: "val"


What am I doing wrong?


Dan..

I apparently made a mistake in creating the SD card. I don't understand how, but
after a recreation of the SD card, all is well.


Dan..

I created an SD card with 4.17.0-r0 and booted my PHL system. However, I am unable to login via mha@10.0.0.1 I am able to access via the wifi, and get a login prompt, but cannot login. The passwd I used previously on 4.16.1 fails. Has mha passwd changed from 4.16.1? Is there a get started doc for ma...

I found the device names to use and am able to get the simple sine generator to output to headset SAMPLERATE=48000 PERIOD=240 #[JACKD] Device ID = '51' name = 'MacBook Pro Microphone', internal name = 'BuiltInMicrophoneDevice' (to be used as -C, -P, or -d parameter) #[JACKD] Device ID = '44' name = ...
