Update e6 20201108

Minor issue regarding the configuration mentioned in #7141108 (small screen e.g. smartphone): Changing from portrait to landscape mode or vice versa the time progress is not refreshed until a short switch e.g. to the playlist window and back again.

I can confirm that update 20201108 seems to have fixed, for me, the local browser update problem seen with earlier versions.

Thanks

Spotify no longer functions correctly after last update. Breaks the GUI.

This might cause a problem if you have more than one UPnP device (like I have).
But functionally it works fine now ....

Wewbfrontend not accessible, update helped short time.
No Access next Day, no Menue, nothing.

Control via 'mpc --host runeaudio.local next' possible.
After changing Song manually, Frontend responds again.

maybe that helps

kind Regards,

Hi @[deleted],

Is there a way to get the soxr resampler to work?

Any change to mpd.conf is lost at the next boot.

Thanks.

SoXR not working? It's already been there with setting: quality "very high".
Custom setting was added to MPD recently. It'll be available on R+R e6 soon.

Can you or someone verify the default Passband End value as 91.3?
Actually, I have no clues for all of them. Please share why tweaking them improves sound quality.

rern,

Thanks for the reply.

The problem is that if you add the format "sample rate:bit depth:channels" line to mpd.conf, and restart mpd, it only works until the next reboot, when the mpd.conf file is overwritten.

I am quite happy to have the Very High quality setting, and would not know enough to customise it.

i noticed the WIFI connection doesn't support spaces in the SSID.

If your SSID is 'The Hole', it will try to connect to 'The'. Even the scan for wifi button only picks up 'The'.

I typically connect via hardwire so I forget to bring it up. It might be this way since Frank's .4 or even earlier versions.

I know I've connected via wifi in the past but updated files via ssh (it has been a long time ago).

Hi rern,

I propose not to make soxr customizable. Why? Resampling is a science of its own. Whoever is interested in tweaking sox/soxr needs a quite good unterstanding of the theory. This forum is probably not equipped to provide meaningful advice how to set soxr's config parameters. Settings soxr quality to "very high" is more than adequate to most or nearly all users.

Hi,
IMHO the only settings that make sense in SoXR customization are the resampling parameters of the output.
From what I understand, when something must resample is better to be in a sample rate that the Dac can handle.
Also for the resampling the SoXR is a better option than the internal resampler.
According the above, the settings that I am using are :

audio_output {
        name            "snd_allo_digione"
        device          "hw:0,0"
        type            "alsa"
        format          "192000:24:2"
      # format          "*:24:*"
        auto_resample   "no"
        auto_channels   "no"
        auto_format     "no"
        mixer_type      "none"
}

The above setting among the :

resampler {
        plugin          "soxr"
        quality         "very high"
}

In theory that makes my system – when it needs with the auto_resample "no" – to resample in 24/192 for my DAC.
If I need to have 24 bit depth - no matter the sample rate - I use the format "*:24:*"

Very useful info can find here :

#5835

Hi s.k.,

So far as I can see, the output settings are configured according to your output device. If you change them by editing the mpd.conf file, the changed settings will only last until next reboot, when the file will be overwritten with what is in the MPD settings page.

Try moving the # to the line above and restart mpd. It will output 24 bits at the source's sample rate until you reboot or make any other changes to settings.

From what rern has said, it looks as if the resample settings will soon be added to the settings page, which will solve the problem. I have several DAC chips which I like to play around with.

s.k.

To edit mpd.conf you first have to make it modifiable with:

    chattr -i /etc/mpd.conf

VERY IMPORTANT: when you are done editing mpd.conf make it unmodifiable again with:

    chattr +i /etc/mpd.conf

(from the "[Guide] Using Soxr Resampling with Rune 0.4 Beta")

Can't say I found that necessary, s.k.

Regarding klassikmann's comment, perhaps rern could add an "include file" line so that those who know what they are doing, or like to experiment, could use a custom file in the home folder.

s.k.

Hi R101,
I stopped the MPD
I made the mpd.conf file modifiable
I removed the # from my mpd.conf file – as you suggested
I made the mpd.conf file unmodifiable again
I reload the daemons & started the mpd
I rebooted the system

The change that I was made was present.
I am on e6 on a Pi2

R101

Hi s.k.,

The difference is that you made the file unmodifiable. In +R e6 it is modifiable. Looks like a good workaround if you don't find any problems.

Your file has two format settings, one of which is commented out. If you just delete the # I am not sure which setting it will use, but I assume the second one.

s.k.

Due to these observations I reviewed my MPD configuration.
The configuration described previously it seamed that convert everything (by upsampling or downsampling) to 24/192 - the maximum value of my dac.

In order to have the less possible conversions I modified my audio_output to this :

audio_output {
        name            "snd_allo_digione"
        device          "hw:0,0"
        type            "alsa"
        auto_resample   "no"
        auto_format     "no"
        mixer_type      "none"
}

And kept the :

resampler {
        plugin          "soxr"
        quality         "very high"
}

With these settings alsa is handling the native sample rate up to my Dac capabilities.
Above those, the SoXR make the downsampling to the maximum possible (24/192).

Notice that only when I tried to play a file with sample rate above 192 SoXR made the conversion

output: converting in=352800:24:2 -> f=352800:24:2 -> out=192000:24:2

In all other cases alsa played the native sample rate.

IMHO if we need to squeeze a little more the system, we have to understand and focus on the SoRX parameters

soxr: soxr engine 'cr64'
soxr: soxr precision=28, phase_response=50.00, passband_end=0.91, stopband_begin=1.00

Some interesting observations there s.k.

If MPD is responsible for limiting the sample rate to the maximum the DAC can handle, that's pretty clever. From the quality point of view, it is a pity it doesn't output a multiple of the original rate, but even soxr will not automatically do a conversion which relates to the original sample rate, so I guess that is too much to expect.

Tweaking soxr

If you have a look at rern's image in #7141127. I do not know how parameters as Phase Response, Passband End, Stopband Begin and so on is modifying the resampling result. Therefore I like to use the dafaults. What I did is to use one-time offline resampling, backup the originals and use the resampled tracks in the MPD database.

I dealt with two open source resamplers:

DSD-enabled SoX
by Måns Rullgård found at https://github.com/mansr/sox (source code only). I compiled the sources for Windows and Linux. Documentation to be found here: https://klassikmann.spdns.de/nextcloud/s/cYZRK72YwZYofBE
ReSampler
by Judd Niemann found at https://github.com/jniemann66/ReSampler (source code and binaries).

Last time I prefer ReSampler.

s.k.

I believe that it is better –in my system - the Pi to act as transporter of the original info and let my dac to handle that info.
After all it is made specific for this job.

So I don’t like the Soxr resample everything – even if it match that way to my dac capabilities.

With my latest configuration Soxr interferes only with sample rates above my dac capabilities.
To tell the truth I am not able to notice audible differences with this configuration.
At least not in my system.
But I shall keep it this way – because I can

@[deleted]
For the multiple resample of the original rate take a look here,
https://www.bitlab.nl/page_id=157
but really I don’t think that it will make any difference.
At least not in my system.

Here are logs with various type of sources.
