Re: Batch processing without GUI

I understand that you want to preprocess several audio files for several hearing losses with gains prescribed by NAL-NL2. To achieve this with openMHA, looping over your audiograms and audio files and processing them following the approach from mhagui_fitting_offline will get you the quickest result...

I was wondering is Rust on the roadmap?
No, it is not. But you are welcome to try it out, a good place might be implementing a plugin in Rust, and report on your experience here.

Re: Unable to complete installation on MacOS Monterey

It matches my experience that some homebrew packages are sometimes broken. In your case, the homebrew qt package seems to be broken. When this happens, you can generally either wait a few days and try again (file a bug report with homebrew if it takes longer) or try to install an older version of th...

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), ...

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...

io.out.device = "hw:0,0"
I would remove the double quotes.

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...
