The labels are the ones committing fraud if they aren't providing product as labelled to a distributor. If someone sold fake budweiser to your liquor store, it's not the liquor store's fault. Qobuz will be at fault here, IMO, if they don't refund money after you complain of mislabelled downloads. If they refund the your money, but leave the album available mislabelled for others to be duped, that's when they have a problem on their hands. What is the policy? If I buy a mislabelled album do i get my money back? I'm pretty sure that the labels are the origin of this issues, but your bud comparison isn't quite correct. The bottles that the liquor store is selling are closed with a cap and they cannot analyze the content. Except MQA files, it is quite easy for a download store or streaming service to check the real quality of the audio files, delivered by the labels. There are server based analysis tools that can do this automatically and quite reliable. It is necessary that the provider recognize that selling or streaming HiRes audio files is a matter of trust because the audible advantages of HiRes music are perceivable but slight, IMO. Without the Sublime or other discount options, Qobuz customers are paying a premium price for this pleasure, customers of most other download stores anyway and they can expect to get what they have payed for. Usually Qobuz offers a compensation when you send a qualified complain to the customer service, but that is not the point for me. I expect that the download store either replace the mislabelled album or, if the label is not willing or able to send a suitable version, delete it from the catalog, respectively publish a comment on the album page that it is e.g. "Recorded in 44.1kHz, mastered to 88.2kHz" like HDtracks is doing it sometimes after complaints. In fact it means, it has been upsampled, but the customer is informed. In the special case that I indicated yesterday "J.S. Odara - Tales Of America", I abstained from complaining officially at the customer service because it is a very nice album, the audible differences from 96kHz to 192kHz are in general very slight and I've purchased the album with the Sublime discount to a very fair price, cheaper than CD quality download. I think it is rude to expect a compensation for this and hope that @David Craff will forward the issue, Qobuz will draw the obvious conclusion for this specific case and other examples of mislabeled albums I've mentioned in earlier posts. Establishing a reliable quality control to prevent such issues would be appreciated and should be standard for all HiRes download and streaming services. Again, it is not my intention to defame Qobuz, this issue applies to the whole music industry with the labels in the first instance. Mark Dirac and R1200CL 2 Link to comment

As you can see in the chart, there is absolutely no signal above 27.7kHz, in this case, not even distortions. I seems as if the quality is slightly better than 24/48, but not very much and presumably not really audible. Anyway, there is content above 24kHz and dependent on the recording and mastering method a 88.2kHz or 96kHz container is justifiable, but not 192kHz, IMO. I'm not an expert in audio recording or mastering, perhaps this somehow special chart is caused by a faulty use of filters. Jud 1 Link to comment

There is one clue that can be used to find what you describe. Some player applications allow deeper inspection into a stream's metadata than others. The Qobuz web player doesn't really show much information about the stream, just telling you simple things like "cd quality" or "24/96khz", etc. LMS shows decompressed flac codec bitrate while the file is playing, that's a metric that doesn't hide anything. If the bitrate appears low there, files will show the analysis behaviour you are describing. For "J.S. Odara - Tales Of America"....I played this via the Qobuz web player, and the app showed an audio stream of 24/192, just like the album is tagged. I then then played it via LMS. First track "American Dream" is showing the stream playing back at a codec data rate of 4632kbps. That's low for 24/192. For 24/96 I should see 3200-3400ish kbps, for 24/192 I should see around 5500-6000ish kbps. "American Dream" falls right in the middle of the two. If this is a new release, and it was recorded 24/192, flac compression was high during mastering. Or it was upsampled from a lower resolution source. This is not limited to hi-res files. Take the Doobie Brother's album "Toulouse Street". If played back from the web player, it shows the album playing back at cd quality, 16/44.1. If played back via LMS, track one "Listen to the Music" is showing a codec data rate of only 863kbps. For TRUE cd quality, I'd expect to see at least 1000-1100kbps there. But considering when this album was originally recorded, you won't see a high data rate, media was 'data rate' limited back then. Album sounds really good when streamed BTW. So sampling rate is one metric, but it's really just a container. How much stuff is inside the container is the codec data rate. That should be right next to each individual track file in the Qobuz app/web player IMO. A new release showing 24/192 and a low data rate is a red flag for data compression in use or upsampling.

I know this numbers from JRiver MC but doubt that the data rate is a reliable indicator for the final resolution of a track and that there is a stringent correlation to bitrate and resolution. I think, beside this two factors it is very much dependent on the complexity of the music as such. Link to comment

I've tried this in several forums since 2015 but the participation was not really awesome. It seems to me that not many audiophiles care about the reliability of the content quality they purchase or stream. As @Musicophile already mentioned, upsampling is usually not an issue for Classical or Jazz aficionados and they are a significant part of HiRes download or streaming customers. I'm afraid as long as due diligence and provenance is a not a significant factor for most labels, download stores and streaming services, nothing will change and it is up to the customers to check the quality of their purchased music with proper analyzing tools and point the resellers and public to mislabeled albums.

rando Posted February 23, 2019 Share Posted February 23, 2019 I trimmed a bit from that post separating the NA Beta, laughable their staff personally vets every track they are adding to the empty spaces, and the well established home office. The actions of both are bleeding together here. I won't go to further lengths defending my suggestion. At the very least a 10+ album list in one place puts a good amount of information in one place for the NYC staff to view. Link to comment
BrokeLinuxPhile Posted February 23, 2019 Share Posted February 23, 2019 Bit depth the same as resolution, right? You increase bit depth, and you increase bit rate and file size. So there should be correlation between resolution and bit rate. Keeping this tied to Qobuz, I'd like to see the bit rates specified for each track and/or individual file sizes when browsing the catalog. Link to comment

I really love the service, and have used it for years now, but the search function and, closely linked, the meta tagging of the stuff on offer, could be one of their biggest differentiation factors in the market, especially for classical, but also e.g. differentiating the different remasters of an album. After all, they are targeting classical music lovers and audiophiles, where those things just matter. And at this point, search is still pretty much a mess. If Furthermore, as already flagged previously, I have yet to find an exhaustive list of all new releases, not just the "selection" Qobuz considers relevant. This is still what I consider Qobuz biggest weakness, or maybe not a weakness, but clearly a lack of positive differentiation. Hi, Thanks for this feedback. I'm in charge of the search engine and know that there is lot's of thing to improve. The best way to help me, if you want, is to explain me your issue. You can answer this question to do that : - Which platform did you use to search on Qobuz? (Desktop, Android, iOS, Sonos...) - What type of product are you looking for? (Release, artiste, track...) - What are you looking for? (ex: 3rd movement of Sonata of Piano no. 14 of Beethoven) - What did you enter? - Did you find what you were looking for and explain? * As I explain before I have created some hashtags to test the search engine. Some of them can answer you needs, but stay as beta and can be change in the future. They only work for release, not for artists, tracks, playlists... Here they are, but don't forget that they may disappear, change or not work properly at any time. - #HiRes to filter only Hi-Res file, but this one is not set for streaming only (for the moment) - #MutilChannel to filter release in 5.1 - #NewRelease to filter only new product < 1 month - #ComposerOnly to filter the query to composer only - #Award to filter release with award (Qobuz award or Press Award) If you have idea for #hashtag, tell me.

It is the job of Qobuz and other download stores or streaming provider to sell their customers the promised contend in the quality they've paid for. It should not be the job of your customers to verify the quality! To show how effective the trying is, I've attached a chart of the current Qobuz top album for download and streaming J.S. Odara - Tales Of America. It is labeled as 24/192 but there is no audible content above 28kHz. 24/96 would have been an absolutely adequate resolution. Only Highresaudio.com indicated this as upsampled and is selling and streaming it correctly as 24/96 album. We have a dedicated department to check the content delivered by the labels. I'm transferring your example to this department. Thank you. Thank you. Hugo9000 and Peter Hyatt 2 Qobuz Product Manager for Desktop, Web Player and Search Engine. Link to comment

Regards I typically access Qobuz via Audirvana or the iOS apps, sometimes the desktop app. A typical search case would be “find all available versions of Shostakovich piano quintet“, and then filter e.g. only highres, or exclude versions not available for streaming. This would however require tagging and grouping of the individual oeuvre, and I’m also not sure how Qobuz handles for examples the different European transcriptions of Shostakovich (Spelled Chosta in French). Another typical use case would be “find all new releases of Chandos in the last 3 months“. And finally, when searching e.g. for Kind Of Blue, you get seven different album versions. How do I easily understand which one is which. I understand many of these require extensive manual tagging, but this would really be useful for the end user. austinpop and Peter Hyatt 2 Check out my blog at musicophilesblog.com - From Keith Jarrett to Johannes Brahms Link to comment

Ski Bum Posted February 25, 2019 Share Posted February 25, 2019 I am a new U.S. beta hi-rez user of Qobuz, which I stream through Roon. I am able to successfully stream most of the Qobuz hi-rez and redbook files, but occasionally I will run into an album that appears to be available for streaming from Qobuz but I get error messages in Roon (to the effect that the song is unavailable) when I try to stream it. For example, the new Jenny Lewis album appears among the Qobuz new albums and I can add it to my Roon library, but the songs are unavailable when I try to stream them. Is this a U.S. licensing issue?

geodon005 Posted February 26, 2019 Share Posted February 26, 2019 I have several questions about Qobuz and I was hoping I could get some answers here. I have truly been enjoying my free trial and plan on subscribing. 1st Question: I was able to get a now-discontinued Chromecast Audio on the cheap and was led to believe that it would allow me to stream hi-res audio (24 bit, 96kHz) from my iOS device (iPhone or iPad) to my Denon AVR. Is this true? If so, does it matter if I use the 3.5 mm plug to split L/R RCA connectors, or would using the digital optical cable be better? 2nd Question: When I listen to a music track on the Qobuz player on my iPad via headphones that indicates it is 24 bit, 96 kHz, is that actually what I am hearing? Is that also true if I listen to the same on my iPhone X using the Lightning-to-3.5 mm adapter? Thanks so much for any help you can provide. Link to comment
BrokeLinuxPhile Posted February 26, 2019 Share Posted February 26, 2019 Hit my first micro service outage here tonight, only lasted for about 10 minutes though, started a little after 1 am EST. No hard outage, just buffers wouldn't fill and playback kept pausing and starting. Was convinced we were going to lose power again while the audio stutters happened, extremely high winds in new england today, lost power twice. And a tree. I checked Tidal and it was still streaming cleanly when Qobuz stuttered. Whatever it was it cleared fast, unlike my near daily problems with Tidal. Qobuz way more reliable for me overall so far, keep up the good work. Link to comment
