Re: using openmha with HiFiBerry DAC+DSP card
Great, the device could be opened for output with two channels! Now the alsa output device could not be linked to your alsa input device via snd_pcm_link. Two options to solve this: Either use the same device for input as for output (if the driver for that device supports linking input and output), ...

Re: using openmha with HiFiBerry DAC+DSP card
I changed to to mhalib = mhachain srate = 24000 fragsize = 55 iolib = MHAIOalsa io.in.device = null io.out.device=hw:0,0 cmd=prepare and get (mha_parser) (mhafw_lib) IO error: (MHAIOalsa) Unable to set channel number for hw:0,0: Invalid argument (while parsing "check_jacks.cfg" line 7) (M...

Estimating physical sound level from sound recording with unknown calibration setup (difficult to impossible)
1) How can I set the input SPL peak level? I mean, if I only have a wav audio file (downloaded from the internet or obtained from anywhere), how can I estimate the input SPL peak level? Is there any preprocessing I can do to normalize or effectively estimate it? Typical hearing aid processing uses ...

Determining available headroom in sound files
2) Regarding post-processing, how should I select the gain value? For example, how did you choose to amplify by -5 or +45 dB as you mentioned? If I am performing automated batch processing (e.g., calculating the amplification for 1000 audio files using NAL-NL2), how can I select or calculate an app...

On judging quality of sound compressed for high hearing losses
Thank you for providing a detailed description of your processing steps! This makes it possible to reproduce your experience. 1) I used examples /01-dynamic-compression/1speaker_diffNoise_2ch.wav as my input audio file. 2) I used 94 dB as the acoustic input level in dB SPL. 94 dB SPL peak level is a...

Re: openMHA 4.18.0 released
I wanted to be able to build from sources. brew install openmha/tap/openmha is actually compiling openmha from sources on your Mac. We do not provide pre-compiled "bottles" for Mac. I found that OSC was not what I needed to have installed. Instead configure was really looking for libio wh...

Re: NAL-NL2 pipeline integration
The offline fitting tool contained in openMHA preprocesses wav files with a dynamic compression prescription rule of your choice. Start it from Matlab or Octave by invoking mhagui_fitting_offline It can process multiple wav files at once. The installation directory of the openMHA mfiles depends on y...

Re: NAL-NL2 wrapper, compression threshold
Hi Florian, thanks for reaching out! 52dB was used for the wide band compression threshold because that value is the default in the NAL NL2 demo software "NAL-NL2 Clinician Edition". You can see this value in the tab "Target Screen" next to the label "Comp. Threshold". ...

Re: fftfilterbank ..The plugin that tried to do this is misbehaving and should be fixed.
Thanks for reporting this behavior! Altering the structure with the mhachain "algos" setting should be possible after cmd=release, then alter the structure, then restart with cmd=start.
I will see how we can modify mhachain in order to improve the error message.
