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 = ...

I changed my jackd invocation, and I am able to run the simple sine generatore cfg. I used: jackd -d coreaudio -r 48000 -p 240 >&1 | sed 's/^/[JACKD] /' & But I did get errors on #echo "connect mha" jack_connect MHA:out_1 system:playback_2 jack_connect MHA:out_2 system:playback_1 [...

I am trying to run openMHA on my M1 Macbook Pro. I try to run a simple sine generator..

I have seen the equalize documentation. It is close to worthless. You comment: "In a nutshell, a vector needs to be provided that contains a linear gain value for each fft bin. The fft bins / frequency range depend on sampling rate and paramter values used in the STFT framework, e.g., the overl...

I would like to use the equalize plugin to implement the calibration of mic & speakers. Using a single peaklevel for a given frequency doesn't seem appropriate. However, I do not see any documentation on how one comes up with the gain values for equalize. Further, what is the frequency range tha...

My code is now running. Not sure what changed. But don't want to waste any more time on this.

If I run the python code (again remote access to PHL) but instead of using the mha.set_val calls to implement the logic, I read the cfg file in via mha.read_cfg('gain.cfg') I get a correct execution... no error -rw-r--r-- 1 mha mha 1219560 Sep 20 13:19 1speaker_diffNoise_2ch.wav -rw-r--r-- 1 mha mha...

I am running a python code that runs the 00-gains/gain_getting_started.cfg as a python code connected remotely to PHL. I get the following error. Running: ['ssh', 'mha@10.0.0.1', 'sh', './StopMHA;cd', '/home/mha/Poz/Poz_examples/00-gain;mha', '--interactive', '--interface=10.0.0.1', '--port=33337'] ...

I want to communicate with mha remotely with python. In a cfg file one says: mha.mute_dummies.min = -120 In the python code I would say mha.set_val('mha.mute_dummies.min','-120') But how would I write mha.transducers.mhachain.split.bte.adm?read:/etc/mahalia/generic-hearing-aid/adm.cfg in my python c...
