I have a couple of questions on very different topics that I've wanted to ask for a long time.

1) When I need to align the contents of my NAS to moOde, I launch the update library function and everything is updated correctly and quickly. I wonder what happens to thumbnails. Obviously, if it wasn't there, now it is, but, for example, if before I had a 300x300 one, and now a 1000x1000 one, even if I view it at the highest possible definition, which is 600x600 (the one I set), the thumbnail is generated from the newest one (1000), or remains the previous one (300). Is the replacement performed with update library? Does running a library update make thumbnail regeneration useless? What does thumbnail regeneration do that update library doesn't?

2) Camilla DSP. I can't figure out how to use it. I have a lot of confusion in my head, perhaps because I have not understood what it is for and what it does. I have seen that it is gaining more and more space within moOde, but the fact remains that I haven't found an easily understandable user guide (for dummies) on the web. Camilla, I believe, should correct the sound in the listening environment, but measuring tools would be needed to determine the corrections to be made, which few people have, so what's the point of all the space and importance that is given to Camilla, (very sophisticated tool that exists in a better hardware version)? Wouldn't a 20 band equalizer be more useful? Is Camilla only useful for headphones? Which approach can be advisable?

thx

1. if a thumbnail is present, it won't be generated; to have the new one show up you need to rebuild the thumbnail cache (and it can take a while)

2. thumbnail generation does exactly what its name implies: it generates the thumbnails, update library, similarly, updates the MPD music database with the new albums/tracks you added; it then runs the thumbnail generator, which will generate the missing images.

Bare in mind that even if regenerating the thumbnails from scratch, you could still be seeing the old image, cached by the browser; so it's always convenient to clear the browser's cache in these scenarios.

Concerning Camilla DSP I cannot help you; never used so far, even if I do want to try it out.

Read through some of it and you will get a sense of how it's being used but basically it's a powerful, general purpose digital signal processing tool for audio that can perform among other things EQ, Loudness, resampling, multi I-O routing, 64-bit Volume and much more. Common usage scenarios are Room Correction, Headphone EQ, Active Crossovers.

It's a fantastic work of software engineering by Henrik Enquist and one of the most important Open Source audio projects :-)
Integration into moOde is compliments of @bitlab :-)
Automatic format switching is compliments of @seashell creator of the alsa_cdsp output plugin.

If you do want to explore CamillaDSP then try the following:

1. Audio Config
SET CamillaDSP to "Peq 10 band"
-- Return to Playback view and start something playing
-- Then return to Audio Config
EDIT CamillaDSP settings

2. CamillaDSP Config
Pipeline editor ON
OPEN

3. Pipeline editor
Click the Filters tab
Adjust the gain on some of the frequency bands or on the pregain filter.
Click the "Apply to DSP" button to hear the effect the changes have on the sound

If you want to make your own Parametric EQ with fewer than 10 bands, lets say 3 bands then return to CamillaDSP Config and in the Pipeline section select "Peq 10 band" and COPY it to a new name then scroll up to the top and select the new name from the "Signal processing" dropdown and then SAVE. Open the Pipeline editor, click the Filters tab and delete bands 04 - 10. Make adjustments to the bands 01 - 03 and pregain and then click the "Save to file" button.

Something like that.

For example, I thought that the parametric EQ was too technical for me until I discovered headphone EQ profiles, at which point I learned how it worked because I had a thing I wanted to achieve with it. I then thought Camilla was too technical until I discovered I could combine my EQ profile with a crossfeed in there, and suddenly I worked that out as well.
So, CamillaDSP is very useful and powerful, but only if you have use for it.  AirPlay support is also very useful, but I don't have Apple, so not for me
