    MQA The Truth lies Somewhere in the Middle

    Why is it that the crowd in your RMAF audience reminds me of a similarly aged group of men that over the last few days have been trying to convince us all about the future of our justice system...and you seem to be having about the same level of success as the women protesting in front of the Supreme Court? I won't pretend to argue who's right on either issue, but I worry any time an older, same gender, same ethnicity group is trying to convince the world that change is bad...

    New Listening Room - Sound Barrier Under Carpet?

    One thing to think about is structural conductivity. We did the double wall/Sheetrock isolation when we built the house and so you can’t hear someone yelling loudly between rooms, but what that didn’t address was the LFE vibrations from the subwoofer, which somehow seem to travel through because they are shaking the room at a more fundamental level. Not much of an issue with most music, but noticeable on movies with explosions. 😀
  3. Ah yes...but no Roon integration... If only there was a Qobuz/HQPlayer/Roon solution...

    Null test 88.2/24 and 44.1/16

    Much of this discussion sounds like a disagreement as to whether it matters whether I use 3.141592653589 or the number below to represent Pi 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196442881097566593344612847564823378678316527120190914564856692346034861045432664821339360726024914127372458700660631558817488152092096282925409171536436789259036001133053054882046652138414695194151160943305727036575959195309218611738193261179310511854807446237996274956735188575272489122793818301194912983367336244065664308602139494639522473719070217986094370277053921717629317675238467481846766940513200056812714526356082778577134275778960917363717872146844090122495343014654958537105079227968925892354201995611212902196086403441815981362977477130996051870721134999999837297804995105973173281609631859502445945534690830264252230825334468503526193118817101000313783875288658753320838142061717766914730359825349042875546873115956286388235378759375195778185778053217122680661300192787661119590921642019893809525720106548586327886593615338182796823030195203530185296899577362259941389124972177528347913151557485724245415069595082953311686172785588907509838175463746493931925506040092770167113900984882401285836160356370766010471018194295559619894676783744944825537977472684710404753464620804668425906949129331367702898915210475216205696602405803815019351125338243003558764024749647326391419927260426992279678235478163600934172164121992458631503028618297455570674983850549458858692699569092721079750930295532116534498720275596023648066549911988183479775356636980742654252786255181841757467289097777279380008164706001614524919217321721477235014144197356854816136115735255213347574184946843852332390739414333454776241686251898356948556209921922218427255025425688767179049460165346680498862723279178608578438382796797668145410095388378636095068006422512520511739298489608412848862694560424196528502221066118630674427862203919494504712371378696095636437191728746776465757396241389086583264599581339047802759009946576407895126946839835259570982582262052248940772671947826848260147699090264013639443745530506820 I would suggest that in both cases the answer depends heavily on what you are going to do with that number. In music a 16/44 recording may fully and accurately represent what most human ears can hear. But listening to music isn't listening to that 16/44 digitization, or a higher rez version of same. Listening to music requires that we perform other operations to turn that digital representation back into an analog waveform that sounds exactly like the original. Everything i have read here on CA suggests to me that the big issues are not in whether 16/44 captures the original waveform in the frequency ranges we can hear, but whether what we then do with that resulting digital information changes what we ultimately hear when it is converted back to analog and played in our systems.

    Article: Should You Rent or Buy Audio Software?

    Some of this is subscribed for by other family members (mostly the kids); and yes, it adds up quickly. The point I was trying to get across is that many of these don't amount to that much individually (i.e. $10/month), but we forget how much stuff we have subscribed to and over time vendors make more money this way than if they sold us a one-time license up front (particularly if they autorenew). I have 4 music software players because I'm curious how they are each progressing (so I support the hobby by supporting them). As to the TV stuff, here in the US I find Network Television (what you can get for free) to be just terrible, so I subscribe to services that provide me with specific content I want to watch (it is cheaper than going to the movies regularly).

    Help CA Find New Speakers

    Chris: Is this still for the same listening room? From your photos it looks almost square, roughly 15 by 15 feet, with limited wall treatments, if I had to guess. Does that suggest you will want to stay with more moderately sized speakers?

    Article: Should You Rent or Buy Audio Software?

    It would be quite interesting to do a survey of how much we each spend these days on various forms of software "subscriptions." The various Roon, JRiver, Audirvana, HQ Player and Photoshop mentions is what we tend to think about. But what about our monthly cable/satellite bill, smartphone bill, our Office 365 license, our security software license, the license associated with our front door cameras, our off-line storage, our electronic magazine subscriptions, Amazon Prime, Netflix,...it just goes on and on. Do you really know how much of your disposable income you spend on monthly/annual subscriptions? The other reality is that we today do expect each one of these subscriptions to provide us with something new or better on a constant basis, in a way that we didn't when we purchased items outright. That is less true of music subscriptions; but there we are getting the ability to access 100X the content for relatively little money, which we gladly trade for the cost of buying content that we may only listen to a few times. So many of the subscription models provide us, as customers, with features, functions, benefits, that we really like. Subscriptions also benefit the incumbent. As someone has already mentioned, the subscription model is very expensive for a startup, because you don't get a lot of revenue up front, the way you would if you sold a single copy. But, over time, the recurring revenue aspects of subscriptions are really great for large companies and serve as a barrier to entry against newcomers who can't afford the R&D spend without a lot of revenue. Lastly, these subscription models work well in a time of wealth and abundance; and in times of rapid change. Few want to buy versus rent if what they bought is obsolete after a couple of years -- better to rent. But if our economy slowed or the pace of change slowed, we all would suddenly pay attention to our monthly subscription spending and probably realize we can reduce by half without giving up that much. In that economic environment, single license purchases are more likely to return. Only question is when we move from today's world to that one.

    Hearing is not simple

    First, we must eliminate as many of the things that our brain simply cannot accept -- like a voice or instrument moving around as it changes pitch, a transient that simply doesn't have enough "snap" to seem real, a wavering in pitch. When we fix these we discover that systems that don't meet "specification" on overall frequency response, or harmonic distortion or other easier to measure and therefore more commonly quoted specifications can sound far more real than those with the [best] specs in the areas where we most commonly get published specs. So, I think it is less about fine-tuning our brain and more about learning which aspects of sound reproduction we are more/less sensitive to. The problem is that, if I had to guess, it turns out that different people are sensitive to different things, therefore the stuff that matters to your brain, may not matter to mine, or at least not as much. Given our own human hearing and processing equipment, we each focus on different sound qualities to tell our brains what is and isn't real. But, we can each learn what we are sensitive to and fine tune our equipment purchases to highlight the specifications that we hear as real.

    Audio memory and hearing aids

    In searching around a bit more I found this new company: the earlens device . They claim to be the first hearing aid to provide 100Hz to 10kHz correction. Interesting.

    Audio memory and hearing aids

    Thanks Peter. I mentioned this part because although it isn't directly relevant to my mother's hearing, it interested me from the standpoint that it does seem as though our ears adjust in a more physical way (such as a limp in walking) where, over time, the adjustment seems like its the correct thing and accurate sound seems like its off. It is one of the reasons I believe that certain people just prefer box speakers and others prefer open-ended speakers, like planars. Once you get "used to" that sound, the other way just sounds wrong.

    Audio memory and hearing aids

    I have always felt that being able to share a great experience makes it that much better. For many of us, these days, there are fewer and fewer people who will sit still long enough to really appreciate a great sound system playing a great piece of music. I too, got a lot of enjoyment out of having a family member ask to hear her favorite pieces on my system. Somehow my kids just don't have the patience for it. Thanks for sharing!

    Audio memory and hearing aids

    My mother used to love to listen to my audio system when she visited. But after she got hearing aids she has stopped enjoying it. When I asked her why, she said that the music sounded distorted. In talking to her audiologist I learned that they a) want patients to wear the hearing aids all the time because "it takes brain quite some time to adjust to the new sound levels and get comfortable with them and switching back and forth just confuses the brain," and b) the hearing aids just amplify the sound range between 2kHz and 8kHz. So, if she is wearing the hearing aids the audio system sounds different than what she was used to and if she isn't wearing them it also sounds different than she has now become used to, either case making music enjoyment much less pleasurable. I'm curious if any CA'ers have an informed views on this. In particular, I'm interested in the notion that it takes the brain time to "relearn" how to hear with the adjusted frequency levels. That seems very different than putting on a pair of glasses and seeing clearly, instantly. And, if this relearning takes time, how much is what each of us thinks "sounds great" just a function of how we have heard it over the recent time frame? Does it mean that a system "sounds good to us" because it sounds like the one we are most used to? Is that why kids can get used to ear-buds and then not appreciate a great sound system when the first hear it, because, to them, it doesn't sound natural? Ultimately, what is the right answer for a person who wears hearing aids and still wants to listen to her favorite recordings? Informed thoughts much appreciated.

    Consensus about upsampling to 512 DSD

    Why does "consensus" even matter? Is "best sound" a democratic decision? Even more, is "best sound for me" a decision best made by a majority of random other folks? What I care a lot more about is that a number of people who have considerable expertise have found that, on certain DACs, using certain software and certain parameters, filters, etc. upsampling to DSD512 can result in a sound they prefer or at least can provide some data as to why it differs less from the original. If I don't have one of those DACs that information isn't all that valuable to me. But if I do, I'd like to at least a) see exactly what software, settings, parameters, filters, they are using on the same DAC and try those for the benefit of my own ears. If it sounds better to me, I'll use it until I find something that sounds better. If not, I'll go back to doing what I was before. Worst case, I invested some time to see whether there was a better solution than the one I'm currently using. Why are so many folks here so strongly opposed to making that investment for their own benefit? If you try it and don't like it, then you shouldn't use it even if 99% of the folks here thought it was better. If you halfheartedly try it (i.e. "I once upsampled to DSD128 using software X and it did nothing for me...") then you should expect as much benefit as you invested in trying. But the "right" outcome is not a religious choice; hopefully it is nothing more than an educated decision to pick a over b -- nothing more.

    Lies about vinyl vs digital

    What does it say about this community that an obvious attempt to rile up the vinyl/digital war (with zero new data) attracts this much attention? Is there nothing new/interesting to talk about? It seems to me that the ratio of pointless battles to useful information ratio is not trending in a favorable direction...
