    A question about MQA

    Hey there. Hope you are fine during these crazy times. I have a question about MQA that I did not have a chance to ask before.
    Let’s say we have a MQA album FLAC 24b 48k and completely unfolding it will deliver 96k like for example the last Tony Allen album on Tidal “Rejoice” (amazing album by the way, I completely encourage you to listen to it).
    I understand that core decoding of MQA will deliver 96k anyway right? So what would bring the 3rd unfold for these albums MQA encoded in 48k or 44k and expected to deliver 88k or 96k?
    On the other hand I understand an MQA file encoded in order to deliver 192k for example cannot deliver these 192k without an MQA renderer.

    Re: A question about MQA

    Another remark
    What’s the purpose of MQAing in 48k FLAC files in 24b and 48k?
    Isn’t the purpose of MQA of showing downsampled files and upsampling them with the different degrees of unfolding?

    Re: A question about MQA

    I’m still trying to figure out why the digital audio world needs MQA. It’s a lossy format plain and simple with a confusing array of musical laundry that needs to be unfolded. Some people love them some MQA so I guess that’s all that matters.

    Re: A question about MQA

    From what I understood, MQA’s goal was to provide the listener with “hi-resolution” tracks without using too much bandwidth.

    But consumers soon realized that MQA is not bit-perfect (it is lossy) plus it is possible to stream bit-perfect high resolution files (think Qobuz, Amazon Music HD, etc.).

    MQA could be useful when streaming for someone who lives in a place where there is limited bandwidth or internet speed.

    Re: A question about MQA

    Hi there. Are u sure MQA is lossy after unfold? When I play MQA with Roon, the Roon signal says it is lossless

    Is the badge HiRes on files dispatched by music streaming companies payable? I mean Qobuz has to pay something to the company owner of HiRes certificate?

    Maybe Tidal has not HiRes certification so its files even in Flac 24b 48k cannot show the HiRes badge

    Instead Tidal has MQA franchise so its files FLAC 24b 48k MQAed in 48k can show the MQA badge. And after all, for a file encoded in 24b 48k, it is better to show a badge (eg MQA here) rather than no badge at all

    Pure speculation and deductions from me. Nothing is proven in what I say

    Why Roon says lossless then?
    Roon claims to be totally transparent about audio signal
    They didn’t grant airplay to be lossless (maybe because of clocking issues) although it is commonly believed to deliver ALAC 16b 44k audio

    Mep, you are incorrect.

    Nothing is removed in MQA encoding, some parts of the signal are just taken out from the inaudible band and added to the signal footer to save bandwidth.

    We can do verbal jujitsu, but MQA is classified as a lossy format. From Wikipedia: "In an interview for online publication Positive Feedback, engineer Andreas Koch is critical of MQA due to its lossy algorithms and compression, along with its licensing requirements; also saying that a format such as this "does not solve any problem that the world currently has."[19] Koch was involved in the creation of the Super Audio CD, the development of the Direct Stream Digital codec, and is co-founder of audio product manufacturer Playback Designs."

    Why in the world do we need a lossy digital format to complicate the playback of formally lossless digital music? I think Andreas Koch summed it up quite nicely when he said MQA does not solve any problem the world currently has.

    A question about MQA

    Dear mep, you know better thank trying to convince me with a Wikipedia quote.

    Andreas Koch is a great guy, and I have greatly benefited from his work as previous owner a Meitner DAC, but it is not too long ago he was under fire himself for promoting DSD. Just read the Linn and other statements why it could not be any good. That was close to ten years ago. I have now a Linn Klimax for the summer house supporting DSD. Reason is always the same, there is something new, and people can’t get their head around it.

    If you ask me, every digitalization is lossy. Therefore, lossless digital in itself is an oxymoron.

    Re: A question about MQA

    Here’s an interesting one to ponder for everyone: if a file is upsampled to a higher bitrate, is it then high res, or is it the same low res in a larger package?

    The amount of information does not change through upsampling. It just cannot.

    My guess is our naming conventions are still evolving.

    Upsampling can't add information. A 16/44.1 file upsampled to 24/192 contains no more information than the orginal 16/44.1 file.

    Re: A question about MQA

    So MQA?
    Is it lossless or not according to generally accepted definition of lossless?
    Roon is wrong claiming it is lossless?

    Now that's a different kettle of fish. If you compare any digital file to the LP counterpoint on a really good analog rig, people with open ears will understand your statement.

    Ok. So you advice to stick to analog sources for the best audio hearing ?

    Start doing some reading so you can form your own opinion. Here is one article that is interesting: https://www.hifiplus.com/articles/hi...-offering-mqa/

    "From the HighResAudio Press Release:

    HIGHRESAUDIO has stopped offering MQA. MQA is NOT lossless, the original signal is never recovered, estimate to recover at most 17bits (reduces the sampling rate), reduces the frequency range, SNR reduced by 3bit, aliasing with artifacts at 18kHz. MQA encoding filters manipulates drastically the original source. No analysis tools are available to verify the encoded MQA content. Therefore no quality control is possible."

    Re: A question about MQA

    Mep is right. MQA is not lossless.

    MQA is one big fat marketing lie, and its technical arguments have been exposed as fraud. The problems with it are discussed is this excellent article:

    MQA: A Review of controversies, concerns, and cautions

    Even the main argument for MQA, temporal de-blurring, may be flawed:

    MUSINGS/MEASUREMENTS: On "blurring" and why MQA probably worsens transient smearing.

    Another technical article by Benchmark Audio is useful as well:

    Is MQA Dead on Arrival?

    There is a whole 780 page thread on Audiophile Style (formerly "Computer Audiophile") where all the technical and marketing lies of MQA are discussed., but above reading, including the link provided by Mep, should suffice.

    Naaah i don’t have the time for that much reading. But I tend to believe Roon when they say MQA is lossless
    Anyway I make no difference when listening into my headphones which satisfy me very well between MQA, HiRes and CD - just like composers, engineers and other people who have done blindtests which were reported in newspapers

    Re: A question about MQA

    The haters keep hating and we continue to have access to more MQA content each week. Over 25000 currently available.

    I don't give a crap what MQA is doing but the end result is what counts and I have yet to come across a album where the MQA version sounds worse than the CD version. Where I have purchased both hi-rez versions and have access to the MQA version any differences aren't even worth worrying about which release might be better. I still haven't paid one penny extra for MQA content or hardware and I have saved myself from having to pay for hi-rez content. There is no downside to MQA.

    You are strongly opinionated and you love MQA. Congrats on your happiness with MQA. I have access to all of the MQA files on Tidal and I don't share your opinion, but that's OK too.

    I'm not surprised. It's on an open question how many Hi-Rez files are really 16/44.1 files that have been upsampled.

    That is not what I said. (EDITED sentence follows) I stated that I have yet to find a MQA version of an album that is inferior to the CD version. (Over time some have stated that is because they are remastering the MQA . There is no way that the entire volume of MQA versions have been remastered for better sound but if some have then good, its free). When MQA was first readily available I did compare several albums where I had both hi-rez and access to MQA versions. There was no consistent result . Either could be better or no differences noticeable. I no longer pay much attention to which version Roon is offering up.

    Your new statement: I stated that I have yet to find a CD version of an album that is inferior to the MQA version.

    You can't have it both ways. I think your original statement is what you intended to say unless you really mean that you have yet to find a CD version of an album that is inferior to the MQA version.

    If you are buying relatively new music that was originally recorded in a hi-rez format, that's great. Any music that was converted to digital from analog tape is a question.

    You are correct. I made a mistake in my second post where I flipped the two. The initial post was correct.

    Where I said you misquoted me is that I have never stated that MQA was always better than any other version.

    Skbe, I’m not in the analog vs. digital discussion camp. I do enjoy both in my system, either at a rather high level. Therefore, I would not discriminate between digital and analog.

    My advice would be, enjoy the music. Use the formats you like, explore and try out different things. To me personally, that is a lots of fun.

    Re: A question about MQA

    Guys did you do a blindtest with asking a friend to select the same songs with different formats in a playlist?

    Would be interesting to have some feedback

    I did it 2 times years ago and recently:
    - I did not recognize Spotify over Qobuz and Tidal every time but was correct for say 70% of the times
    - Never recognized CD vs MQA vs HR. The times I did were due to guesses not choices

    Why?
    Isn't it a good way to test if within your system and your own hearing capabilities you can recognize which sounds better to you?
    Because at the end of the day what is the point of MQA, HIRES, original analog sound, CD if one cannot hear the difference?

    If you enjoy blind testing audio gear with your buddies, that’s great. I would rather listen to music.

    You realize that is significantly more than available DSD releases. I believe those have been out for 20 years.

    Your “real high res” is most likely just upsampled 16/44.

    It’s a bit like high res for dummies, isn’t it?

    Re: A question about MQA

    This happens every time there's a new format, the investors go to war, it's like election years. The idea of streaming a small package that is opened at its destination to provide up to 3 times the data just sounds smarter than throwing out the information that doesn't fit. sending a 128kbps that opens to a 320 quality file at its playback source has to be a good thing when the majority never use anything more than their tablet or smart phone and spotify or tidal. This is the intended market for mqa.

    I don't agree that MQA was intended and marketed exclusively for people who listen over their phones or tablets. What are you basing that statement on?

    It is!

    (Although there is also some real 96/24 or 96/192.)

    But this is too funny. I have been ridiculed here for still sticking to just CD by people who were praising the virtues of "high-res", but as you say for the most part (or at the least for a large part), they haven't listened with their "hi-res" to anything other than Redbook CD format anyway.

    ***

    And by the way, as you will note, I consistently put "high-res" in quotation marks: the name "high-res" ("high resolution format") is a misnomer as it implies that CD is not high resolution. That attitude is based on a misunderstanding of digital theory. And especially with recent advances in digital implementation, which come closer to ideal theory than in the past, this attitude also flies in the face of audible practical reality.

    If you can't get extraordinarily high resolution from CD (physical or file format), in terms of timbral micro-detail, separation of instruments and quality of spatial information, something is lacking with your digital setup and your system.
