    This is the thread I'm referring to in another thread today (my link there to this thread is waiting for approval as of now).

    In post #10 you can see the results of our testing with the Cambridge 851N.

    Please note: By accident/mishap, this thread is missing many posts from simbun, so the context can be hard to follow.

    And for the Marantz & Rotel models that I have encountered. This display problem is very common sadly.

    Re: Cambridge Audio / StreamMagic only displaying first artist

    I've raised the multiple artist issue with Cambridge and, following a fairly disappointing "that's how it is" reply, I've arranged for it to be escalated and it's now with the developers for consideration. I spoke with a second support person and they confirmed it's on the list for discussion. So there is hope. Displaying all the artists assigned to a track is a fairly basic display requirement I'd have thought.

    I completely agree. Illustrate's implementation, attention to detail and attempts to circumvent issues is to be applauded.

    However, some hi-fi manufacturers implementation of the protocols involved is poor, and, when I have pointed out certain bugs/issues, their attitude and response has also been poor to say the least, and that is a shame.

    No problem, I've seen much much worse, by myself too

    Yes I do understand that you'd want to leave the audio untouched, but the one example we have of such processing in the current product is with MP3, using "as MP3", where it does decode and encode.

    It's obviously possible, although whether it's worth the investment for Illustrate I don't know.
    That one example does not leave the audio untouched, as re-encoding mp3 is a lossy process, even with the highest bitrate. I'd prefer if the tags could be removed without re-encoding the audio.

    So I'm not sure what you mean, maybe I'm not reading you right. When you say "It's obviously possible", are you referring to "decode and encode"? Cause that's not what I'm after.

    The alternatives don't look better to me. I like the power and customization a music server offers. I like having a streamer on top of my amplifier, and often use it without the app, only the remote control. Then the display on the unit is the only place where I can see track info - so it's nice when it's accurate. Other times I use the app, browsing the album covers. Nice to have choices, depending on your mood.

    Hmmm, yes, it's a shame, but don't hold your breath here.

    I was a big fan of the UPnP/DLNA protocol (10 years ago), and although Asset UPnP works very well, getting hi-fi hardware manufacturers to implement firmware that works reasonably OR as hoped, in my experience does not happen.

    Yes, you'll be able to stream audio ok, but handling ALL the possible metadata/artwork formats well, is another matter.

    You either accept the manufacturers limitations OR you look for another solution... as I did.

    By stripping the files from tags I don't mean by decoding / encoding, I mean just removing the tags, keeping the original audio untouched.

    I think it would be better than transcoding when you don't really need/want transcoding, only stripping of tags.

    I'd prefer to have untouched audio sent to the renderer if possible. Playing the original files gives you a hint of the source when you have various file types and it's great to see whether you play lossy or lossless.

    Haha, it's a tempting move but I see your wink - it's impractical of course and would disguise lossy mp3 in a lossless format.

    Transcoding has a similar disadvantage, since the original file format is disguised - flac & mp3 are both displayed as pcm.

    But that got me thinking about this:

    Could "no metadata is sent in file" also be achieved for "as is", like in a "no tag" option?

    I.e. selecting "no tag" (or similar name) would not touch the audio, only strip the file from tags.

    Thus hindering dumb control points from pulling tags off the audio files.


    Or as a General setting e.g. "Don't send metadata in files"

    Or as a Control Point Specific setting e.g. [NoFileMetadata]

    The result from our testing of the 851N:

    Code:
    FORMAT    STREAM    AA present    AA absent
    
    FLAC/MP3  AS IS     single A *    single A *
               WAV       multi AA      multi A
    
    AIFF      AS IS      multi AA      multi A
               WAV       multi AA      multi A
    
    
    * not from Asset, pulled from source file
    
    ID3v2.3 or ID3v2.4 didn't matter for MP3/AIFF
    
    Multiple ARTISTs present in all files
    
    AA present = multiple ALBUM ARTISTs tagged

    I don't use RG (yet) so I hadn't read that part in the manual... But the settings could be clearer about the need for transcoding. Also, "in a format other than 'as is'" could also make 'as is single' sufficient for RG, so that could be clearer too.

    Sorry, that sentence was a lapsus/error on my part. I cut down a longer rambling text about the 851N not obeying/conforming to UPnP, and mixed it up when I pasted it, didn't notice that.

    It's probably because how ID3v2.4 stores multi-value tags, I bet you'd see the same with MP3 files.
    No, for flac & mp3 it's the same, and aiff differs.

    Indeed... Considering the price tag and the fact that 851N was Cambridge's flagship model a few years ago, the tag handling is really subpar. And the StreamMagic firmware is shared among Cambridge streamers, so one wonders why they don't care to fix this.


    My buddy who owns the 851N says he's fed up with testing for now, so testing BubbleUPnP Server has to wait. Hoping for the [SimpleArtist] update, but he would need transcoding as well, which he thinks he shouldn't have to do just for correcting one tag on his flagship model... Cambridge, are you reading...? Probably not.

    Btw, the link is clearly seen now, and also thanks for your support and ideas.

    And another oddity we discovered: When playing aiff files streamed "as is" the 851N displayed multiple ALBUM ARTISTs whilst playing - as opposed to single ARTISTs when playing flac files.

    How can this be made to work for multiples too?
    preformat:=artist:=[artist]-a-

    Why transcoding when applying ReplayGain, I'd think "as is" is sufficient?

    Yes I already tried that but it didn't work:
    AS IS: No difference (=single artist still pulled by 851N from flac file)
    TRANSCODING: "Unknown Artist" was displayed

    And even if [SimpleArtist] gets fixed the 851N probably won't obey...

    (By the way the links are almost invisible on my display, perhaps underlining or something would help to make links stand out more?)

    Re: Cambridge Audio / StreamMagic only displaying first artist

    Great idea to use preformat for testing. We setup this
    Code:
    preformat:=album artist:=[album artist]-aa-
    preformat:=artist:=[artist]-a-
    and the 851N showed the following on its display whilst playing:

    AS IS
    artist read from flac file

    WAV TRANSCODING
    if album artist is present: -aa-
    if album artist is absent: -a-

    So the 851N normally likes to read directly from the flac files, but when transcoding it's getting the preformatted values from Asset.
