Better than that--I can point you to the samples themselves. But first--you weren't clear which you wanted...do you want the 320k MP3 that's indistinguishable from RedBook or the 320k MP3 that's easily distinguished from RedBook. It's a kinda important difference. The first one's easy: silence.mp3. Sounds just like the source. Yes, it's a bit of a cop-out too but I'm trying not to fan flames here and I may get grudging agreement from a few subjectivists on this one. The next one is harder--there's a sample called "eig" that's a pretty good general-purpose MP3-wrecker. Google will help you here. IMO it's a great example of a track that just cannot be fixed by throwing more bits at it. It's not that hard to understand. MP3 uses algorithms to figure out which data can be discarded without causing an audible difference (and IMO the LAME project has done a fantastic job with those algorithms, keeping yestertech like MP3 competitive with other lossy formats). Careful enough study of those algorithms and their assumptions would allow you to custom-create a track that wouldn't compress without audible artifacts. Also, given the enormous amount of music in the world, there will always be several tracks that naturally won't compress right. There's no question that these tracks exist. The question is always: what's the likelihood that one of those tracks is in my collection? -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=61877 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

There really are tracks have not yet been distinguished with any certainty from RedBook at 320k, and there really are tracks that are easily distinguished with high confidence. The question is: if this is the case, would you trust that your collection fits entirely into the former category without testing each track? The most important point is that people tend to misread DBT results. If someone claims a DBT proves people can't tell the difference between X and Y, they are simply wrong. Flat wrong. It doesn't work like that. The most lossy-friendly results possible will say only that X and Y could not be confidently distinguished within the limits of the test. That last clause--"within the limits of the test" is what makes most PC-ABX testing worthless, because those tests are more constrained by their listening setup than the media they're testing. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=61877 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

I've seen this claim a lot on the Internet, but there's never much in the way of facts behind it, then or now. For example, while I'm sure you could hand-pick some tracks that produce these results, that's hardly the way any objectivist would test. You could also alter the definition of "CD Quality" such that it doesn't mean "sounds indistinguishable from a CD", but then if you go that far you don't even need to bother testing--just ratchet down your definitions until they meet your needs. I've seen quite a lot of DBT's of 128k MP3's. The results are that they don't sound like lossless.

The first thing is I'm not seeing anything about detecting or preventing the audible interference patterns that can be generated from ultrasonic sounds. Maybe that's not the point of this study, but if it's not then they're not breaking any new ground. Also, the link between detectable brain activity and perceptible sounds doesn't sound solid (again, I'm not sure this was a goal of their test so I can't fault them for it). Certainly they went through some trouble making subjects sit still and avoid visual stimulation during the test, but more things stimulate the brain that just that. Did subjects have caffeine in their systems? Stomach discomfort? Did they get bored in the scanner and start thinking about Hawaii? Would any of that have shown up on the scans? The PET scans showed that the brain was doing stuff, but is that "stuff" hearing? Or is the subject just going over their shopping list? If they are certain that the parts of the brain they're scanning are exclusively responsible for hearing, then why did they bother making the room dark? That sort of thing.

Failing to demonstrate a perceptible difference in a double-blind test does NOT mean that the difference can't be perceived! Failing to prove the existence of something is not the same as proving the lack of something. Also, a badly-designed test will give bad results, double-blind or not. Just because A/B audio tests cannot give good results does not mean that ABX (or other double-blind) audio tests always do. Designing a good test is hard, and bad tests of any sort are generally worthless. > The Objectivist typically considers that to allow oneself to be > influenced by these other factors is some kind of character flaw. Not at all. We just prefer to measure one thing at a time. If we wanted to, we could do a double-blind test of identical audio to show exactly how much influence the brand of the amp had on the perceived sound quality. It's not a character flaw, it's just a variable which could be tested. Most people are interested in sound quality, so we tend to control for that. If you do a test that allows multiple factors to influence perception, then it's difficult-to-impossible to sort out how much each factor contributed. Again, it all boils down to designing a good test. > They therefore draw the conclusion that the difference heard is not down > to any such external factors, but must be due to some problem with the > blind comparison methodology that prevents the differences being > detected. And I absolutely agree. Any tester should thoroughly document their methodology so that others can pick it apart and even re-test with any identified flaws removed. This is NOT the same thing as "your test didn't give the results I though it should have, therefore there must be something wrong with it". You have to actually identify the flaw and how to fix it. > Why not just accept the fact that external factors do modify what we > hear, and it is human nature that it does so?

I think the schism will remain, despite your best efforts. People like certainty (especially when spending lots of money), you can't have certainty without people making definitive statements, and you can't have definitive statements without testing. There are fundamental differences about what qualifies as a valid test. For example, I've seen some exquisitely designed nonblind audio tests. But they're nonblind, and therefore worthless, but subjectivists love them anyway. Then there's PC ABX tests, which make double-blind testing so easy you can get results without having any idea how to do a perception test. Also, typically worthless, but pseudo-objectivists love them anyway. That's the tension. People want answers. Tests give answers. Most tests are bad tests and give wrong answers, but people don't care about that so much, because what they really want is justification. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=61877 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Luddites, er I mean audiophiles
Hey, I'm a DBT-loving Luddite and I'm offended! Just kidding. I am actually a DBT-loving Luddite, but I'm not actually offended. "Luddite" is frequently a label that gets thrown at people who just have different priorities than much of society. We don't fear or hate technology, we just don't see what the big deal is. We actually like technology that fits our personal priorities. Take me. I'm a well-paid professional (in the tech industry no less) male in my thirties and have never had a cell phone. That fact alone brings conversations to screeching halts and starts people wondering if I ride a donkey to work. But here's the thing: I don't hate cell phones. I don't fear them. I simply have never NEEDED one. I already have a phone--it's at my house. If you need to get ahold of me while I'm out, I've got voicemail. If I need to get ahold of you, I'll go home and call you. All of my communication bases are covered as far as I'm concerned--no need for an upgrade. Also, FWIW my phone at home has a cord that attaches the handset to the base. I like it that way because it sounds better. No, really, no donkey. Now take your "Luddite" audiophile. They will buy a bag of magic rocks to make their amp sound better. They will buy green markers by the truckload. But they won't buy a networked music player. It's not as crazy as it sounds. Bags of magic rocks and green markers have a placebo effect (that's my DBT-loving side talking), don't actually make anything sound worse, and most importantly of all, they do not screw with any part of the tactile/emotional/nostalgic side of the listening experience. Networked music players do. An audiophile will tell you it's all about the sound, but they can identify their favorite albums by smell or touch. A networked music player makes music incorporeal. It does in fact get rid of part of their overall music experience, so they do not want it. Many, however, cannot square this with their belief that Hearing is the One True Sense, and they end up manufacturing fairly feeble attacks on the sound quality of networked players. It's not fear or hate so much as lack of understanding combined with the lack of any desire to learn more. Like iPhones for me. I wouldn't even recognize one if I saw it, and although a quick visit to apple.com could clear that up for me, I really don't care enough to even do that much. I like SqueezeBoxes myself. I've bought several. But I understand the joy of pulling an old cherished album out of its sleeve, and I know that I'm giving that up. There IS a downside.

Yes, absolutely, no question about it. And the reason is that perception is everything in the market. If everyone THINKS Product A is better than Product B, people will buy Product A--and depending on how important that difference is perceived to be, people will even pay more for Product A. Potentially a lot more. Which product is actually better, or if they are actually pretty much identical, is irrelevant. I'm NOT saying they create demand by trumpeting some irrelevant difference as if it were an advantage (although Monster cables certainly does plenty of that), but by knowing the customer base and their biases, and creating what they want.

Yes, hobbyists can and frequently do ABX testing on low-end systems, but audiophiles can also do them on high-end systems any time they want to disappoint themselves. A/B testing on the other hand produces garbage results no matter what kind of system you're doing it on.

It doesn't really matter about the type of music because that instrument positioning argument is pretty much pants. It's based on a misunderstanding of how joint stereo works, which is a bandwidth-saving technique employed primarily by lossy encoders, but also by some lossless encoders such as APE (this last bit is a clue to how much it impacts sound). These are some of the REAL artifacts of lossy encoding, in descending order of easiness to hear/obnoxiousness: - Warbling. Let's say you have a long sequence of rapid-fire percussive noises. Typically faster than drums, like applause and sometimes castanets. Each sound may be imperceptibly time-shifted, but collectively, it'll sound like the audience is clapping underwater. - Ringing. You'll hear this on brass instruments and piano, maybe others. It will just sound more metallic than it should. - Pre-echo. Another form of time-shifting. It basically makes percussive sounds softer. Like the drums have been stuffed with pillows. - Hissing, etc. There are lots of lesser artifacts that actually sound pretty natural, and you very likely won't spot them just listening to the compressed version. The only way you can really spot them is the carefully compare against the source, preferably in a double-blind test. Be warned that if you just do A/B testing, your brain WILL imagine differences between tracks, and your knowledge of which track is lossy will lead you to erroneously believe you've spotted a difference.

A consumer is frequently in a bind when it comes to their audio: they often have no control over compromises someone else made (at the recording, mixing, mastering level), and they have some control over the playback environment but it comes at a very high cost. I was mostly pointing out that encoding is one of the few areas where the consumer has complete control, at a very low cost. For an audiophile, that's enough reason to go lossless right there. End of story. The rest of the world needs to weigh the benefits and costs, though. The cost is a few dollars worth of HD space and a small amount of time and effort. Everyone agrees about that part. There's some disagreement about the benefit, but I'm going to spell out what the non-audiophile world thinks, at great risk of grievous personal injury. The benefit is *cough* that some people (probably not you) may be able to perceive an audible (but not necessarily unpleasant) difference on some hi-fi systems (probably not yours) and only on some tracks anyway (probably not in your collection). For the rest of the world, it's pretty clear the costs outweigh the benefits, so they go lossy. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=51021 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

This is a very important point that's often lost in the noise of format arguments. The best any digital format, lossy or lossless, can hope to do is to sound exactly like the source material (typically the CD). There are a lot of things in the recording, mixing, and mastering processes which can and do alter the sound much more significantly than lossy encoding would. In that sense it's already lossy when it's on the CD. Lossy encoding just potentially shaves a little more sound quality off something that's typically been hacked at pretty significantly. The whole vinyl/SACD/DVD-A/HDCD argument is mostly about these other much more significant factors, seasoned with just a dash of snake oil for zip. But, since this is the audiophile forum, it's not a question of relative significance. Lossy encoding is a compromise that the listener simply doesn't have to make, so why do it? -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=51021 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Transcoding lossy->lossy degrades the quality, even with the same PAM. Layman's explanation--the orginal encoding takes waveform X and converts it into waveform Y (which should be very similar to X, but nevertheless different). Transcoding takes waveform Y and converts it into waveform Z. Z!=Y BECAUSE Y!=X. If you're starting with a different waveform, there's no way you'll end up at the same place after the transformation.

You have to master the audio extremely well or it will run into vinyl's limitations and sound like crap. CDs on the other hand are very forgiving. You can compress and amplify the audio like crazy (and other stupid things) and it will sound much, much better than if you tried to master an LP in the same fashion--some people will even prefer the badly overcompressed sound (shrug). So whenever I hear vinyl and I think it sounds better than the CD, I recognize that either a) the vinyl is based on a totally different and better-sounding master, b) I'm enjoying the (inaccurate) coloration provided by the vinyl medium and playback, or c) I'm imagining things. Because I like to fancy myself an objectivist, I'd like to believe that if the vinyl master was used on the CD, the CD would sound much better than the vinyl. I feel the same way about HDCD and SACD--of course they sound better--they tend to be mastered much more competently than CDs, and I can't demonstrate that the advanced technology is responsible for the improved sound at all. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=34379 ___ audiophiles mailing list [EMAIL PROTECTED] http://lists.slimdevices.com/lists/listinfo/audiophiles

If you're looking to prove something, you need to prove it. Every assumption you make has to be independently tested, or you need to modify your original test to not include those assumptions. i.e. your initial test might very well be a fine single-blind test. But you'd need to perform a completely separate test simply to prove that subjects could not perceive that other subjects have raised their hands (because that has not been established). And another to show they couldn't hear you making the tweak. And yet another to show that they could not perceive you reacting to other subjects raising their hands (turning your head, turning to one side). And multiple tests and placebo tests to weed out dumb luck. And procedural error in any of these sub-tests would invalidate the main test, because your main test relies on them.

Re: [SlimDevices: Audiophiles] A/B Testing method question
For what it's worth: Telling the subjects to raise their hand when they noticed a change wasn't necessarily "unblinding" the test, as long as there was a possibility that no change would happen during the course of the test. Having multiple subjects in the same room, even with their eyes closed, pretty much ruined the test, though. If you ever want to re-do this test, isolate your subjects (test one at a time), and perform multiple tests per subject (on the order of 12 or more), including tests where no change occurs. Come up with the criteria for a "positive" BEFORE the trial starts, such as raising a hand within 30 seconds of the tweak. Then consider any other hand-raising to be a false positive, even if it's at X+1 seconds. Otherwise you'll end up adjusting your criteria to fit your data, which makes the whole process suspect. Then at the end you'll have a nice big pile of data to work with. Then it will likely be a pretty good single-blind test. It will not be double-blind because you are in the room with the subjects, both to make the tweak and to observe the hand-raising (and ninja-like as you may believe yourself to be, your subjects may be able to sense you making the tweak).

None of the above. I'm not an audiophile myself but I'm nevertheless fascinated by audiophile stuff.

[SlimDevices: Audiophiles] Re: Portable hi-fi
No. ;) But we could help you find the best thing possible with that limitation. Please preface everything below with "my personal opinion/experience is..." - FLAC support limits you to iAudio and Rockbox'ed devices. - No device offers good enough sound quality to make FLAC support relevant (unless you want FLAC support to avoid the trouble of transcoding) - iAudio X5, some iRiver models, and (no, not kidding) the original iPod shuffle reputedly have very good sound quality compared to their peers. I cannot verify this because I only have an X5 - The iAudio X5 and iRiver models seem to be favorites of the Rockbox project - I would recommend using RockBox--it won't improve sound quality, but it does add things like wider format support and gapless playback (which is a must-have for classical fans) - Make sure that your studio-class headset really is all it claims to be Good luck! -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=30642 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: WMPlayer / wma lossless - EAC / FLAC
EAC is definitely better. If your CDs are in pristine shape, you won't see the difference, but otherwise you will. EAC will protect you against the nasty and rather obvious pops and clicks that plague a lot of tracks ripped from CD. And sometimes the scratches are not terribly visible, so a visual inspection may not help you determine what condition your CDs are in. Go with EAC, because it's the only way to be sure. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=29534 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Location of table of all supported formats and bitrates
Ah, with that I'm afraid I can't help you. You could always experiment yourself to find out, but that's certainly not as easy as a simple chart. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=29354 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Location of table of all supported formats and bitrates
By "supported", do you mean "it works" or "SlimDevices will give me official technical support for this". That could be a significant distinction. Since server-side transcoding is very flexible, I'd say that any format that can be understood by the server platform can work on the client. Since SlimServer runs on any platform you are likely to have, you could safely say the clients work for every format you are likely to consider. So I guess you should specify what your exact needs are. If you're asking "What works?", well, everything works. I'm sure even MIDI files could be made to work. (Hey, that's a good idea...!) I'd follow the ripping guideline in the Wiki (http://wiki.slimdevices.com/index.cgi?BeginnersGuideToFileFormats) FLAC is a good choice for the uncertain. Even if you decide at a later time that you want to use a different format, because it's lossless, you can safely convert to a new format without losing any data (unless you choose to convert to a lossy format). Also use EAC if it works on your platform--not all CD rippers are created equal. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=29354 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Science and audiophilia
At the risk of making absolute statements on sensitive topics, double-blind tests are the only scientific way to gauge whether or not a subject can perceive the difference between two stimuli. This isn't limited to audio. There are plenty of perception tests around vision, smell, etc. that follow the same rules. Smell these test tubes--which one is different? And so on. This goes on in the very real scientific field of perception every day. That said, setting up a controlled laboratory in your own home is not as easy as some objectivists may lead you to believe. There's the playback hardware itself, the listening environment, and several biological factors (can tinnitus be amplified by blood pressure variations and caffeine? I don't know, but it's plausible. What about mental distractions/altered states? Et cetera) If a double-blind test shows that the subject cannot identify the different stimulus with certainty, that does prove that the subject can't tell the difference--but only within the parameters of the test. If one of those parameters was off (say, the subject was hung over but did not want to inform the tester), then the test isn't really valid in other circumstances. So I guess my point is: objectivists are correct that all differences can be measured (go ahead, call me autistic!). However, failure to measure a difference may be a failure of methodology rather than an indicator that the difference cannot be perceived by the subject. People who classify themselves as subjectivists have a lot to offer in terms of setting up the test environment correctly, but it's not meaningful without the double-blind test at the end. That's my two cents. Really not trying to troll, perhaps succeeding anyway. My first venture into this fray. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=28368 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
