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.

Re: Feedback Suppression
I do not know the afc algorithm very well. There is a good chance that its implementation is still too CPU-hungry to run on the PHL. We usually use a combination of frequency shifting and coherence filtering to achieve feedback suppression in real-time openMHA setups. The afc algorithm stores the op...

Re: Feedback suppression configuration
Please see https://github.com/HoerTech-gGmbH/openM ... mha.m#L200 for how to feed a buffer of audio to MHAIOParser, and line 203 in this file for how to read the processed result.

Re: Auto Start Node server on Boot
If I understand you correctly, then your log on the PHL shows (1) that your nodejs app has actually started, and (2) that your nodejs app reacts to your connection by logging "Cannot get /". If this is not the reaction that you want, then you need to fix this inside your custom nodejs app,...

Re: Time and Calender Settings
I am generating some files using the timestamp but it looks like PHL's calender is wrong. As nmichael says, the PHL does not have real-time-clock hardware, and therefore cannot keep track of time and date between reboots. Also, its operating system does not connect to the internet on each reboot to...

Re: Serving React App with node-red
Searching for serve web pages with node-red finds a couple of hits that look relevant to your project.
That said, the PHL runs Linux on a 32 bit ARM processor, so any other common technology to serve web pages from Linux can be realized on the PHL, and may be cheaper, CPU-wise, than using node-red.

Re: Filtering and softclip in transducers plugin
If you want to employ a softclipper before the output side FIR filter of the "transducers" plugin, then please use the separate plugin "softclip" as the last plugin in the chain that you load into plugin "transducers". The purpose of the softclipper which is integrated ...
