Uniti core assigns wrong metadata

I think Core ripping metadata lookup is still a bit hit and miss actually although Naim won't admit that publically, so I suggest you delete both discs, rip disc two first, edit the metadata and after it has been scanned and recognised, rip disc one and edit that metadata if you need to. Hopefully that should do it.

You might want to let Naim support know of the problem too, but I dont think they will be able to do anything about it.

Hi David, exactly what I have done so far, OK will send naim an email. First double cd to have done this, played both on a CD player and they definately are different!

One question is whether the same holds true with the same Cd ripped with, say, dBpoweramp on a computer. I have found itbquite common for CDs to have incorrect metadata.

Just purchased a 2 cd of king crimson, absent lovers. Cds rip OK, but disc 2 keeps getting assigned as being disc 1, and associated track info, they are definitely different discs. Tried manual assigning metadata, also correctly looked up on musicbrainz, then saved. Left for an hour, still reads as being disc 1, it will not keep both discs saved, only one disc is allowed to be playeable

Any thoughts.

Have you tried the other metadata lookup options, i.e. Rovi and FreeDB, to see if they can do any better than MusicBrainz? Have you tried a manual 'reset database' after editing metadata? 

Rovi is the problem, the others find the metadata, but it does not save? I will try a manual reset database, will try in the morning

thankyou

Ripped disc2, changed metadata, then reset database overnight, still shows as disc 1 and associated tracks. Have to see if naim responds to my email

It's weird that it won't save the edited metadata. I haven't met any disc that did that.

Are you able to edit the metadata and for it to save it on any other disc? You are remembering to tell it to save as you leave the edit screen?

Otherwise and assuming that Naim don't have a magic solution, I suggest you could rip the errant CD on a PC, sort out the metadata and then save it into your downloads folder. You can't edit metadata on albums in the downloads folder of course.

Think I have tried everything. I did manage to get the track info correctly saved for disc2, if I used a bogus cover (say van Morrison). This would then save after leaving edit, and play. As soon as I ripped disc 1, Disc2 was then overwritten.

I think as you say, dig out my old pic and rip on that?

thanks gazza

The other thing you could look at is if you go to "custom" in edit metadata, the identity of the disc is shown (a jumble of numbers and letters if I recall correctly). Can you alter that and then edit in the metadata from one of the non-Rovi sources?

David

I will try that. Is there any way of resetting the default from Rovi to another such as freedb. So that the original rip is looked up by freedb or another, but not Rovi. If not I think that could be a firmware update for the future.

There isn't such a way at the moment.

I think the sure fire way would be to rip both discs on a PC, edit the metadata if necessary (if you rip using iTunes it might even get it right) and then upload both to the downloads folder.

Yes it is I have them ripped, looking for my USB dongle.

Tried your suggestion David, still end up with only disc 1. I will report back on any results from naim email?

Done the download, though not ideal after you have spent this amount of money on the core. I have 6 other cds somewhere at Naim, that would not rip to understand what is wrong, not the end of the world.....but when a cheap pc drive does it with ease, it's annoying.

Ok another approach, in case you can't rip the CDs on your PC for some reason.

You could rip with the Core, copy the files from the Core's music folder to the downloads folder and then delete the original rip in the Core (using the app to delete of course). Then same again with the second CD. I think you need to be careful what you copy, because you don't want to be copying any Naim indexing stuff.  But if you are ripping in WAV, then copying the actual music files and the artwork will be sufficient.

i think this should work ok, but I haven't tried it myself.

Another idea would be to make a copy of one of the CDs and rip the copy. This works for discs that the Core finds unplayable, but again it's not something I have done myself, so I'm not quite sure how the metadata editing part will work.

Thanks a David, I have ripped on my PC and imported via USB to the downloads, will wait and see if NAim  have any ideas. My feeling is if I could change from Rovi, it would be OK. Playing the album now, wife hates it, Fripp and co are a bit divisive.

thanks gazza

Our postings crossed. Glad you sorted it.

I think the Core is very picky about CDs. For example I had a new sealed double CD (I forget what it was) and the second disc wouldn't rip properly in the Core, even though it did rip fine in my Unitiserve and played perfectly on my CDX2. Examining it really closely with a magnifying glass revealed a very faint scratch, almost invisible. I returned the discs to Amazon for exchange as the second disc was apparently faulty and the replacement discs when they arrived were fine.

Like you I have sent a disc to the Naim developers team which ripped with audible errors on playback even though it ripped perfectly in my Unitiserve and also played fine in both my CDX2 and my car.  Naim confirmed they had reproduced the problem with my disc, but I never heard any more. I bought a replacement CD and that ripped fine in the Core.

Hopefully when Naim have all the new units out of the factory door, they will take another look at the Core's ripping engine and work out what it is doing wrong, especially as the Star uses the same engine I think, so it is something that needs sorting. It should be fixable with a firmware change I suppose.

Interesting, I only sent my cd,s in to try and help them mske their product, more robust. I was at first told to just let them keep ripping, but I do not think that leaving them spinning for several hours is a good practice, long term.

My disc that wouldn't rip properly didn't take much longer than usual. But it abandoned a couple of tracks. And the one that ripped with audible errors took the normal time to rip and according to the tipping monitor was ok.

What I have done with double albums that are actually just a single album that the format of CD or LP forced to be split, is renumber the tracks of the second album, like 201, 201 etc.I don't know how that would work with the Uniti

I don't think any of the problems described regarding failure to rip properly are unique to the Core. I had all of those problems and more when I initially started using Unitiserve units. After trying two or three units, I too supplied several visually perfect discs (which also played just fine on my CDS2)  to Trevor Wilson who ran some trials and proved that it was data spikes on the CDs which caused the ripping engine to fail. Naim purchased replacement copies of the discs which all ripped fine.

I here what you say Clive but I still have my Unitiserve as well as a Core and if the US rips the CD fine but the Core doesn't, as I found, that's a shortcoming of the Core as far as I can see. And I'm not talking about old CDs that have seen better days, but brand new full price releases.

Sorry I must have misread that earlier. In that case, I agree there is something odd about the Core. I was hoping the Core would ultimately prove to be the ideal solution if ever I needed to consider a replacement for my NS01, but as long as it works and Naim Audio is able to service it, the NS01 is THE best ripping, storage and back-up solution as far as I'm concerned.
