Re: mha startup in Mahalia

Yes, on the PHL 8, 16, 24, 32, 48, and 96kHz are supported. If the -r parameter value set in JACK does not match a supported sampling rate, the next lower one is selected, but this is not reported in the terminal output.

You can use jack_bufsize to get the actual value.

Re: mha startup in Mahalia

JACK is also started by the mahalia system service. You can do that manually with the following lines: export JACK_NO_AUDIO_RESERVATION=1 jackd -S -R -P90 -dalsa -dhw:boneaudioext -r<SRATE> -p<FRAGSIZE> -n2 Make sure that SRATE and FRAGSIZE match the values used in your openMHA configuration.

Re: mha startup in Mahalia

Hi Dan, the mha process is started by a system service called "mahalia". Excecuting sudo systemctl stop mahalia will stop the service and the mha process accordingly. I recommend to let the service start once at boot time as it also sets some important sound device parameters. sudo systemc...

Re: Manually Entering a Fitting

Hi Dan, if you want to create arbitrary gain rules the dc plugin would be the one of your choice. It uses a gaintable that describes which gain is applied in which band depending on the input level in it 'gtdata' parameter and the related ones 'gtmin' and gtstep'. The Matlab fitting tool basically g...

Re: Headset volume

I'm assuming that you're using the Portable Hearing Lab with the generic hearing aid configuration. The volume control therin only affects the headphone volume at the line out. It is there to adjust the volume for an (uncalibrated) headphone. The ear-level devices are calibrated and gain is controll...

Re: Microphone connection

I assume that you're using a Portable Hearing Lab. This hardware provides 3.1V voltage supply on the line in (pink). If that matches your mic specifications it should work.
