352.8 khz and MQA titles on Deezer.

Using Deezer Hifi because of my Highend equipment I was very amazed when I was streaming some albums from the 2L label,  mostly classical and choir. Normally it's the usual 44.1khz but suddenly... 352.8 khz!  And also MQA !! . Switching back and wordward to other albums( checking  the system wasn't cunfused) every 2L album gave the same highend results.

Dear Deezer,  what's going on???  

Thank

Jakob

    Hi Jakob,

    So this image I’m attaching (previousy shared by you) is from your Fiio M11 Pro?

    If so, is it from its built-in music player?

    Hmm… so it’s only available on mobile devices with certain DACs connected to them? I don’t see this functionality on a desktop, and even if the files were indeed different from our standard FLACs that would necessitate bit and resolution mode switching from Deezer app itself, which it doesn’t do. Does that mean that mobile apps have a different way to pass the audio, bypassing the native decoders and just dumping the stream over to the DAC which would automagically select the correct mode for playback? Hmm…

    All in all I would prefer either more hi-res (but still standard) FLACs and/or DSD. Both are open-source, standard, lossless, and perform quite well. Along with mode switching for whatever audio hardware you’re using. The concept works quite well in Swinsian app on macos: https://swinsian.com

    Hallo Buckie. 

    Some mobile devices have there own DAC,  such ass Fiio or Astell & Kern f.i. 

    The Fiio i own has the feature to upsample everything to DSD ( not that i use this much)  

    Here you can see an example. Playing Joni Mitchell on Deezer you can see that the Fiio upsamples this song to 2.8mHz ( DSD)  .

    When i play some songs from the 2L label on Deezer nothing is upsampled. The stream is a right away 352.8kHz MQA.

    What I find wrong in all of this, is that the official Deezer representatives don’t have any idea about what’s going on. It’s like their developer side and, worse yet, planning side, is a black box that is completely out of their reach. You’d think that Rudi and Jamie would be the first to know and announce that but no, it’s the users.

    Not blaming Rudi or Jamie, of course, but it does makes one wonder exactly why Deezer chose such a weird totally non-transparent multi-layered development and management model. What elusive purpose does that serve… Maybe just trying to outdo Apple in the secrecy department.

    Hey @Buckie 

    I get you completely but we're also waiting for a reply from our Partnerships teams about this. They've been so busy recently with massive connectivity projects for this year (finally we'll see a lot of improvements in this area, after so much demand from the community). And based on what I've known, we've had a brief partnership with MQA in the past - this isn't something we're actively working with at the moment - but we're waiting to see if this is something our predecessors have set up a while ago.

    So it's like a rare find, which we still need to dig deeper to get to the bottom of it. I'll be in touch once we have more info.

    Hi @Rudi 

     

    Any update on this? 

     

    FWIW, many of the quoted tracks are definitely MQA - or at least my iFi ZEN DAC is decoding/unfolding them as such… 

    Is this something you’re likely to resurrect, or provide higher-than-cd quality (MQA, DSD, DXD, etc) in the future?

    cheers,

    Matt

    Hey Matt, @eschatologist71 

    No updates so far as we're working hard to improve reliability on the app at the moment.

    However, it remains on our radar to perhaps work on a Hi-Res version for Deezer in the future. I'll pass on your feedback :wink:

    Hi guys, how can I see the streaming quality like on your posted screenshoots? Maybe I´m blind but can´t find any option on iPhone app; only “HiFi”, that´s it. Or are you using a additional player/software? Thanks in advance.
