Uniti Core metadata

Posted by: Klout10 on 05 September 2017

Question regarding my Uniti Core: ripping albums and editing the metadata works good for me. Last weekend, I've imported all my music from my QNAP NAS to the Core, because I’d like to have all my music stored on a single location and use the NAS solely as aback-up - but I've found out that in some occasions the Core messes up some of the metadata.

For example:

Pink Floyd - The Wall: on the NAS I've had two folders "The Wall" and "The Wall [CD 2]" for some strange reason, the Core changed the artist assigned to "The Wall" into: "various" instead of "Pink Floyd" ... since the files are in the downloads folder, I've used MP3Tag to have a look at the metadata, but it still says "Pink Floyd" ... no single field is called “various”. Furthermore, the second album still has the correct tagging.

Another example:

As above, when having double albums, the first album is always named "Album_Title" and the second (or third) album is named: "Album_Title [CD 2]" ... after the import on the Uniti Core, the first album is - on some occasions - displayed as "Album_Title [disc1]" where it seems that the Core adds the 'disc 1' denomination ...

I'm pretty meticulous when it comes to metadata and have spend a fair amount of time in order to all this stuff right, so now I'm somewhat dissapointed and even considering to leave everything on the QNAP NAS ...

Any thoughts on what might cause this?

Interesting. But I'm not sure what's going on. If these files are still on your NAS, you could define that as a share and then you will be able to see the files twice, once from your NAS and once from the downloads folder. You should immediately see those albums that the Core treats differently and in what way.

When I first got my Core, in the days before we had in app metadata editing, I could see the music on my Unitiserve and the same music imported into the Core. Really quite a lot of artwork was changed by the Core (maybe 30% of albums) and it has to be said that even after the Core firmware update which gave us metadata editing and supposed acceptance of previous user edits when I did a fresh import from my Unitiserve into a new Core internal disc, the Core still changed lots of the artwork and one or two albums imported as "unknown album" despite the Unitiserve knowing exactly what they were.

What audio format are the files ?

Posted on: 05 September 2017 by Klout10

Interesting observation indeed, all the files are in flac format. Ripped either by the Uniti Core or a Naim HDX ...

Ah well....If the files on your NAS were ripped by a Naim server (e.g. HDX) then when you import them into the Core they should go into your Music Store rather than your downloads folder and the Core should respect legacy edits but it can (and perhaps will) look up from scratch albums that weren't previously edited. You can see that if you look at the metadata in the Naim app for an imported album, there will be a Legacy tab and if you select that then you can see your previous edits.

So I reckon there is your problem.

Hi David, thank you for your reply, this is really helpful to me. to make the story complete: my 400GB HDX was about to crash and therefore, all the music was stored on the NAS. Once on the NAS, I've edited a couple of files using MP3 tag for the items that the HDX couldn't deal with at the time, e.g. the "questionmark" and "slash" symbols. After the import of about 650 albums to the Uniti Core every single album ended up in the "downloads" folder ... isn't that strange? Maybe the most easy thing to do is delete these albums from the "downloads" folder and re-rip the CD's again ... the total number might not be very much ...

That is odd. I understood that the Core knows whether the rip was made by a Naim ripper/server because of the presence of s small file metadata.naim and those rips should go into the music folder not the downloads folder. This is certainly what happened when I imported from my Unitiserve. You could talk to Naim support about that but I expect they will suggest that you do the import afresh and if your NAS is dying or dead, that may not be an option.

But the Core handles its own rips better in my experience than imports, in terms of metadata and of course you can edit inside the Naim app which is very convenient for small adjustments, although as a metadata editor it is functionally very limited as everyone knows, especially for classical and multi-artist/collection albums.

So if you don't have too many CDs to re-rip, that's probably what you should do. You can delete the files from the downloads folder later unless your interior disc is short of space, which it may be if it's an SSD.

I've also contacted Naim with regards to this topic, but I did not got a reply from them. It might be the most convenient approach just to re-rip the approx. 10 concerning albums.

Indeed metadata editing is a bit limited on the Core, but since I don't own classical music it's not a big deal. Too bad it is is not possible to edit the "genre" but I believe a future update might address that.

If it's only 10 albums then I would definitely re-rip. 

In my personal experience if Naim support doesn't reply quite quickly then they probably arent going to, for whatever reason.

I'm certainly going to re-rip the albums involved ... probably metadata handling and editing is not as straightforward as it appears

Hi,

I received an email from you yesterday afternoon and an additional one this morning - are those the emails you refer to above?

Yes indeed

I’ve played around with re-ripping a couple of albums by the Uniti Core and editing the metadata; I’ve found a repeatable issue with the editing of album titles. For example the album "Document" by R.E.M. but this is applicable to other albums as well.

 The album look-up returned with the album title: “Document [Import Bonus Tracks]”, I’ve edited the album title to “Document” with the Naim app. I was surprised to see the album playing on my Uniti Atom and have the old “un-edited” album title displayed in the bottom of the app. On all other locations the correct album title is displayed. 

 Uniti Core, Atom as well as my iPhone 5S are running latest software and app versions.

That sounds a bit like you need to clear a cache in the Atom, but I don't know well enough how to do that or even whether there is a cache to clear.

The reason I suggest this is because the app just tells the streamer what to pull from the Core and the Core must be serving the same files whichever streamer it is streaming to.

But I haven't heard of this happening before.

Did Phil throw any light on why your imported files were going into downloads rather than the music folder? I only ask because I am interested in how the import works and I suspect we will see more such issues pop up on the forum as the number of Cores out there increase.

I raised it with the software guys and it looks like if the folder structure has been changed so that it is no longer a "clean" server music folder then it is pulled into Downloads as it cannot be guaranteed to be a clean structure...

It's with them at the moment though...

Thanks very much for that Phil. That makes sense as Klout10 was importing from a NAS rather than direct from his HDX. I recall a previous occasion where someone had the same query that was discussed at length in a thread but we never did get to the bottom of that (I think Richard said you were on holiday at the time!)

Thankx again Phil, your assistance is very helpful.

Please bear in mind that these are the details; in the meantime I'm so very happy with these units ...

Am I the only one to experience the above?

Have you tried rescanning the drive after the edit? On the Unitiserve I found it could take weeks or months for an edit to show on the app unless you did this. Also, clear the UPnP cache on the app.

Core edits normally show up within a few seconds or at most a minute or two....(I too have experienced the Unitiserve unwillingness to acknowledge the new!)

Thank you for your replies ... I think it has nothing to do with the Uniti Core as I've just found out that these files play perfectly on my mu-so Qb ...
