    The synth probably used square waves or something close. That is why you can see the equally spaced little peaks across the audio spectrum when the loud note is played. It is physically impossible for the stylus to trace a square wave or the cutter to cut it in mastering. So what you see is the tapering off high order harmonics or even distortion. Because our hearing rolls off at high frequency plus the fact that the audio has rolled off (down around -72 dB in the demo) these high frequencies are inaudible. Of course, some magic eared audiophile will argue otherwise.

      @rich1051414 5 лет назад

      Interesting. I always assumed it was low pass filters in SOME stage of production that was responsible for heavy rounding of square waves introducing distortion. Understandable, a square wave is a very unnatural thing, and only really became intentional out of necessity due to limitations of early digital audio creation.
      The fact the stylus itself does this automatically is not something I had thought about.

    • @dtz1000
      @dtz1000 5 лет назад

      @Olav Viking But most digital music cuts out the frequencies above 20khz. This is not how natural sound is. Natural sound includes frequencies above 20khz. Vinyl also includes frequencies above 20khz which is why it sounds more natural to many people. I would rather listen to sounds that are closer to how nature intended them to be. Name calling people who point out this flaw in digital music is not going to solve this problem.

      @ReaktorLeak Didn't you see the video where VWestlife reproduced ultrasonic sounds using a cheap record player? It proves that even cheap record players can reproduce ultrasonic sounds.
      Vinyl sounds more natural because ultrasonic sounds exist in nature. So they should not be artificially removed as happens with digital music. Ultrasonic sounds have been shown to create alpha waves in the brain which gives positive feelings of relaxation. You don't get that with digital music stripped of ultrasonic sound.

    I did not expect to see that. But I'd like to see a double-blind test with "vinyl is better" audiophiles listening to the original 96kHz recording of that synth song, vs. a version of the same song where everything above (say) 24kHz is cut off to simulate the frequency response of the first recording but with the music of the second recording.

      While analog records obviously do not have the cutoff that is seen for digital recordings, I am a bit skeptical of that second example really being a good demonstration, considering the LP is marked as a 4 channel recording it probably has supersonic content that encodes the difference used to reconstruct the 4 channels from the audible sum channels.
      More importantly, though, is that the recording systems for a quadraphonic recording would likely include low pass filters to suppress the higher frequency content of the sound, so you would not get interference between the sum and diff channels.
      For example, I believe the CD4 system specified only up to 15kHz for the audio.

    • @Ts6451
      @Ts6451 7 лет назад +3

      Oh, I see. That does change things a bit, such a recording would probably not have such filters.
      After thinking a bit about it, I now think that even if it was a CD-4 recording, it still would be a viable example that records could store sound above the audible range, as the system would rely on it being possible to reliably reproduce those frequencies. So, I withdraw my concerns on this point.

    • @tisbonus
      @tisbonus 6 лет назад +1

      Yes. That's called a psychoacoustic phenomenon. When lower frequencies are cut, the remaining signal has less weight and the overall perception is brighter, clearer, cleaner and more spatial audio.

    @itsupport9757 6 лет назад +5

    I think that it is pretty much beyond dispute that vinyl can record up to 122 kHz is what I read. What I am unsure of is the benefit of recording frequencies beyond human hearing. Keep in mind that if there was merit to recording high frequencies that are well out of the range of human hearing, the Redbook Standard could have had a sampling rate of whatever was felt to be necessary. Maybe the CD would have had to be a bit bigger or a few minutes would have been taken off of the CD but the fact that 44.1 kHz was used seems to indicate that there was no need to using a higher sampling rate for audio.

      @Rocker01ndomablE let's assume you're right, it's not how science works of course; nothing is "obvious" in science. But for the sake of argument let's assume vinyls can indeed play sounds up to 45KHz, hell let's push this into the absurd, let's say it could play up to 100KHz. Would it matter? You cannot hear anything past 20KHz if your ears are flawless. And unless you're a newborn baby they aren't, but let's assume you can hear up to 20KHz. If your vinyl plays a 25KHz sound would you hear it? No. So does it matter than it did? Your dog could enjoy that higher frequency response but unless you replace your eardrum with that of a dog you will not hear it. And this is of course assuming your speaker can play 25KHz, because guess what: they're not built for dogs, so we don't bother making sure they can play frequencies that we're unable to hear. And even if they did play such tones, which some speakers can, the sound would still need to be heard by our eadrum which would act as a fiter for anything that isn't 20-20000Hz assuming flawless condition. And no matter how pure the sound is, no matter how much you spend on a vinyl player, amplifier and speaker set everything will still need to go through or millenia old, pretty inaccurare, and impossible to improve hearing apparatus. Stop trying to achieve perfection, no matter how hard you try you will never get any more quality than what your ears can hear. And they are far far from being perfect, even in their "advertised" 20-20000Hz range

    Good video. Frequencies above the audible range contribute directly to the sound dynamics. Most people would not tell the difference between a 320kbps mp3 file with a 16kHz to 20kHz lowpass filter and a full range flac at 16bit. But it does make a difference to cutoff the ultrasonic portion of the sound.
    I would recommend to you vwestlife to use a spectrogram with linear scale to view the high frequency range fast and clear. In my foobar2000 interface, it's a necessity for me in order to detect heavily encoded songs and to evaluate the quality of compression on the fly. It also shows any notch filters and interference waves.

      When it comes to commercial material, you're absolutely right. However, some low-pass filters, standalone or even in codecs (MP3), can sometimes cut a good deal of the frequencies in the neighborhood of 20kHz
      In digital photography, some shoot their pictures at the highest resolution possible and then re-sample them back to lower currently common commercial image sizes.
      When archiving vinyl though, I'd prefer to go 24bit/48kHz at the least to ensure the best possible results.

    • @mspenrice
      @mspenrice 6 лет назад

      If they're affecting the lower frequencies we can actually hear, surely when downsampled or filtered their contribution will be added to the low frequencies anyway, just the same as they would be in the ear with its limited range of sensory cells tuned to different frequencies? You can't have it both ways. Pressure waves and their recording aren't magic, they don't know whether it's a machine or a human receiving them.

      Some remasters are done better than others. The Led Zeppelin vinyl remasters are good. Are they going to beat the Classic Records all analogue, or some editions of originals? No. They compare favorably, and are cheaper and bought new. Music On Vinyl puts out consistently good reissues using digital, but a lot of them are above 44.1K, like 96k/24bit. Useless ones are like Four Men With Beards, some Plain Records (Ween, Elliott Smith, Sonic Youth) stuff. 44/16 and yucky!

      John Bliss; I cannot agree with you on the (current) price point of brand new vs. old/original records, regardless of their respective/comparable sound quality, (which is a whole other topic to dispute, which I'm not gonna go into here), but as far as current record *prices* go, the brand new pressings of albums which are available new in retail stores now are WAAAAY more expensive than their CD or downloadable MP3 versions are, which is extremely stupid marketing I think! (It's like the record companies are only trying to consider selling them to "audiophiles" or maybe DJs, more of which don't really care about the price than the average consumer does, which really pisses me off because it's just plain *greed*, simply because records are seeing a slight resurgence in popularity!)... From what I've continued to see for the last few years with every new album that comes out, is that if it's available in a vinyl version in the stores or on Amazon, etc., the vinyl version is always anywhere from 2-4 times as much as the CD version for example, quite often even more than that, which is totally ridiculous!...
      I think that the vinyl versions of any given album, whether a new release or a "classic", definitely *should* be even less than the CD version, (or at the very most at least comparably priced to CD or MP3 versions of that same album), but I have yet even *once* to see that with any new album that I want to buy!... And as far as "classic" albums like Pink Floyd, Rolling Stones, Beatles stuff, etc., the "new" pressings/cuttings of these types of albums are sometimes close to around $100 or so!... That is just completely unreasonable!... With the current retail record/vinyl pricing strategy as it is now, if I'm gonna get a brand new release album then I always just buy it on CD because it's always much cheaper than the LP version is, and if I want to ever get a classic album on vinyl that I don't already have, then I'd much rather just get a very well taken care of original copy of it at a garage sale or the fleamarket, etc, as records at those types of sales can very commonly be had for $1 each or sometimes even less!

    • @mspenrice
      @mspenrice 6 лет назад

      Well, heck, that's just a plain good idea even with CDs. I can show you even "remasters" of classic 80s rock albums that are utterly ruined vs the original release, and the difference can be heard well inside of 44.1/16 stereo, probably even if you downsampled to 22/8 mono (only bought the later copy because the first got damaged... I thought something had gone wrong with my hifi until I analysed the new one vs what my computer could read of the old).
      For vinyl releases, I wouldn't trust them as far as I could throw them. And I'm not even a subscriber to the high sample rate / bitdepth religion, as impressive as the spectrograms in these videos are. I mean, the one thing that's actually encouraging about them is that the discs being shown off obviously have quite a bit of wear left in them... I think all the old vinyl I have, partly from my parents' collection and partly from second hand stores, has been played almost to death and the effective sampling quality in digital terms is now decidedly down around the 32khz/12bit range. Doesn't stop me enjoying the music, but it does have a rather characteristic, overly resonant, dulled treble, high noise floor sound to it, that the very few brand new discs I have (other than a couple of very cheaply pressed late 90s EPs) all lack, even those which are likely pressed from a digital source.
      As for prices, I haven't found them to be _super_ expensive, but then I still remember the days of paying almost as much as a 12" costs now for CD releases, back when CD was king. Anything less than about £15 for an album is acceptable, under £10 is good, and upto £20 can be sort of justified if it's something amazing and the recording quality is good... beyond that, well, it had better be rare as hell. I've seen some places trying to charge £25+ for reissues of the White Album and so-on... I mean, come on, guys, stone cold classic it may be, but it's also common as muck and only the most pristine 60s originals are actually valuable.

    • @mspenrice
      @mspenrice 6 лет назад +1

      I wouldn't be surprised about that, particularly for singles and even moreso the "inner" tracks of a typical LP. With the sharper side angles and smaller front-to-back size of an elliptical stylus, it should have a much greater ability to reproduce high frequencies... although the absolute maximum frequency may actually be slightly lower, it'll have a much steeper roll-off at the top end and a much shallower one at the low-midrange end, so preserving a lot more of the high frequencies you can actually _hear_ .

  • @ShawnTewes
    @ShawnTewes 7 лет назад +5

    Adding to a comment made about the frequencies >20khz being nothing but distortion/noise, it would make sense that the harmonics in the synth notes are probably caused by micro vibrations from the needle. Plus, a master tape from 1971 probably couldn't reproduce anything higher than 30khz, even though according to Wikipedia, some records go up to 50khz, and a high end phono cart can go in excess of 120khz. Of course, science is one thing, but obsessing over whether analog vs. digital is better is another. Good experiment.

    • @mspenrice
      @mspenrice 6 лет назад

      Question is, how high an effective sample rate can the disc physically hold, and what can the needle read? As we're dealing with both a cutting head and a read stylus of certain minimum dimensions, and a medium passing them at a certain minimum and maximum speed, it should be possible to theorise what the genuine maximum sample rate of a given vinyl system is. Beyond the limits of your stylus, even if the master disc was been cut with an extremely fine head, and the pressing system and plastic substrate were of a suitable quality to preserve every last feature of that, you won't have the upper frequencies reproduced in any meaningful way because the edges of the needle will simply bridge over the narrowest points of each wave. I mean, they're generally oval, which helps to preserve the higher ranges somewhat because it only presents an effectively flat edge to the very smallest features, but it'll certainly start to suffer a drop in intensity from the point at which the disc features become smaller than its front-to-back size.
      Like if you have a stylus that's half a millimetre front to back, and it's on the very outer edge of an LP (say, exactly 30cm out, which is just under 12 inches) turning at 33.3rpm... effective media speed is about 1.883m/s, or 1883 millimetres per second, that's a maximum unattenuated frequency of just 3766hz (equivalent to a sample rate of 7532hz, or roughly what you get from a telephone), and if we consider the edge of the needle to be as good as flat at the point where a front-to-back chord is only 1/10th that (at which point the side to side movement in response to even the largest amplitude high frequency wave will be very much reduced), it's an equivalent sample rate of "just" 75.3khz (and 48khz equivalent where it's about 1/6th to 1/7th). This is pretty good, but not quite up to the levels demonstrated, and will require quite a bit of treble boosting EQ for anything much over 10khz to be properly audible - hence the need for pre-EQing of the record at the factory to reduce bass frequencies and accentuate treble, so the needle has a chance of picking them up at all and isn't thrown totally out of the groove by strong bass, and a similar but not as strong reverse correction in the phono stage.
      However, that's at the outside edge. If we move further in, to about the diameter of a 7" single, say 17cm once the lead-in is discounted, things are rather worse. Speed around the groove circumference reduces linearly thanks to c = 2 pi r, so instead of 1.883m/s it's now 1.067m/s; unattenuated frequency response is a mere 2134hz, equivalent to a 4268hz sample rate, and at our 1/10th size chord that's of course 42.7khz equivalent; raising the speed to 45rpm takes us up to 57.7khz equivalent, but it's still not quite as amazing, especially as we've got rather less amplitude (if I make a blind assumption that it's about 1/8th that of full travel, we've lost about 3 bits of resolution, or around 24 decibels of power).
      Just before the lead-out, which I'm going to take as approx 10cm (I'll check this momentarily with a ruler and an actual disc), things are even worse; for the LP, equivalent sample rate is just 1/3rd what it originally was, or about 25.1khz, though the single isn't quite so bad, at a still-acceptable 33.9khz.
      This is of course all a stab in the dark as I haven't got any stylus specs for maximum dimensions and degree of ovality to hand, but half a millimetre seems like a good place to start. I think I've bought at least one before that's about that size, and think I've seen them ranging from 0.3 to 0.7mm... the former giving you about 41khz equivalent still (after EQing, so the top end might be kinda noisy) at the inner edge of a disc.
      Assuming of course it's been cut with a stylus that's the same size as it or smaller, of course, else the grooves themselves are going to be relatively smoothed out and lacking in the tiny details.
      Really what I think this shows is that if you want the ultimate treble response from your records you need to play microgroove 78s... ;) ... even with a 0.7mm needle, going by my blind formula above, you'd see 42khz at the inner edge, and at the 10" outer diameter it'd be closer to 105khz equivalent (roughly matching what VW is getting on the spectrograph...)

      Follow up to my own comment: The stylus I have installed in my own deck at the moment turns out to be a 0.7 by 0.2mm type, which makes it damn near oblong and can probably be considered more or less rectangular (maybe at the level of 0.1mm, as there's *some* tail off, though it's very steep after that first half)... that raises the maximum frequency without attenuation to a healthy 9.4khz *at the outer edge* at 33.3rpm (actually that's for 12" diameter, real records are *slightly* smaller, but not enough to change this to any less than 9.3khz... and at the inner edge - no narrower than 4.75" for an LP - it's about 3.7khz; for 45s, 7.3khz at the outer edge and 4.5khz at the 4.25 inch inner diameter), and probably double that with only mild attenuation.
      Funny, I figured that it was going to make the headroom figures higher but those seem lower if anything. Maybe we still have some meaningful reproduction out to where the stylus chord is only 0.05mm, IDK?

    This is an interesting video. It's also worth noting that the majority of LPs produced since 1979 have been digitally mastered, due to the introduction of digital 'cutting delays' in the mastering chain.
    A delay is used to pre-adjust the groove spacing ahead of changes in audio amplitude, in order to squeeze more music onto the disc, and also to generate the 'shiny spaces' between tracks.
    Previously, a tape deck with two playback heads was used to provide the delay.

    • @mspenrice
      @mspenrice 6 лет назад +1

      There might be a digital system measuring the amplitude in order to space the grooves properly, but does that necessarily mean that the audio itself is being permanently converted into a digital form and then that copy used to lay down the final track? Seems it would be a lot easier and cheaper to simply record the maximum amplitude every millisecond or so and simply use that for controlling how fast the cutting head moved inwards, with the actual signal chain from analogue master tape to analogue disc still being, well, the same old analogue setup they already had in place.

    Could a test recording be done in which an LP that has a frequency range below 20 Hz and above 20 kHz, in which we delete or mute only the 20-20 kHz frequencies so we can test our ears to see if we can truly hear or make out with our ears these remaining higher and lower frequencies? I have some Sony headphones that can go from 3-100 kHz. It would be a great test for me and other so we can either prove or disprove these "internet experts" that claim all human cant hear outside of these frequencies. But even if we can't, how can we prove that the combination of those higher and lower frequencies do not add to the other frequencies and/or compliment them?

  • @jvzn2848

    Vinyl has a much higher frequency response, but it also adds distortion. Digital has a limited but sufficient (and practically pefect as far as humans are concerned) frequency response with no distortion.

  • @Perplexer1
    @Perplexer1 7 лет назад +1

    I don't get one thing. Ok, you mentioned you removed the preamp so let's say the built-in circuitry does not limit frequency response to 20 KHz like many non-pro preamps perhaps will. But how do you get over 20 KHz spectrum if AT95E specs say that the stylus/cartridge frequency response is 20 to 20,000Hz. Can someone explain that ?

    • @vwestlife
      @vwestlife  7 лет назад +6

      In the late '90s audio equipment manufacturers agreed to limit their frequency response tests to only 20 - 20,000 Hz because that is the commonly agreed range of human hearing. Before then you would often see tweeters and phono cartridges advertised as having response up to 30,000 or 35,000 Hz or sometimes even higher. This extended high frequency response can still exist in new audio equipment made today; it just isn't measured or advertised anymore.

    • @pennyloafers
      @pennyloafers 6 лет назад +2

      I would also like to add, that even if it's rated to say 20kh, it will still capture/reproduce beyond said frequency. But it will be below some threshold they used to get the advertised rating. Not taking into account filters.

    • @SoyAudiofilo

    We can only consciously hear up to a certain frequency. Perhaps at higher frequencies it becomes subconscious but still matters to how we feel about it. Perhaps the sense of the highs above 20 khz is there just below consciousness but still influences our feeling about the music. Bats locate insects between 20 kHz and 60 kHz. I'm not sure things have to be consciously noticed to be important. We govern and screen out certain sensory inputs to maintain mental control but those inputs still hit our brains.

    @electronash 7 лет назад +41

    The apparent wider frequency response of the LP is a pointless "test" tbh...
    You can't hear much above 20 KHz anyway (especially as we get older), and it's very likely that the original master recording chain would have had a low-pass filter too.
    That doesn't mean to say that vinyl is any less enjoyable a medium because of it, but the suggestion that it's somehow technically / objectively superior to modern digital recording formats is silly.
    We have very well defined tests for gauging the quality of an audio recording vs the master recording.
    Those are things like THD+N (Total Harmonic Distortion + Noise), and dynamic range tests.
    Even if you argue that vinyl (or tape etc.) are more "linear", the objective tests are exactly how we can compare each type of recording medium though. They tell the whole story.
    But, there is a lot to be said for the "character" and perceived added "warmth" of older recordings, and the tactile feel of actually collecting them etc.
    There's also a LOT to be said for the crappy "loudness wars" thing on most modern recordings. It basically spoiled the quality of most CD music from the late 90s onwards.
    Speaking of distortion - there's also a very high probability that all you are really seeing on the spectrogram is the distortion and harmonics caused by the needle itself bumping along the grooves in the vinyl, and unlikely to be any actual (wanted) recorded audio other than noise. Again, we can't hear that high up in frequency anyway.
    Unless you know exactly how the recording was mastered, then this sort of test can't really show us much.
    I expect 99.9% of humans wouldn't ever be able to tell the difference between an original vinyl pressing or a high-quality 24-bit / 96 KHz recording of the same vinyl in a blind test (with precisely the same volume levels / speakers / amp / equalisation etc.)
    Of course, many of the older recordings started life on a studio tape deck too - If the aim is to get as close to that tape master as possible, then technically the modern digital standards win every time (if properly done).
    EDIT: I get the point of the vid was to also show how many newer recordings are generally a bit crap though, and I can't disagree there. lol
    EDIT2: Oh, and the sharp cut-off of frequencies above about 20 KHz in digital recordings is entirely expected, and necessary. Even for the higher sampling rate / bit depth recordings, there is a well defined standard for the amount of roll-off to get the best quality for the audible range. Showing the graph up to 100 KHz isn't going to show the slope of the low-pass filter properly, as it's not zoomed in enough. Again, anything about ~20-24 KHz on the vinyl recording is just unwanted noise anyway, and can only have a detrimental affect on the objective audio quality (unless you subjectively prefer the character of vinyl or tape etc., which is fine.)

      Yep, but there is a video previous to this which suggests that the LP is somehow "better" because it shows frequencies above the ~20KHz range of human hearing?
      It's just going to be harmonics and noise above the normal recording anyway.
      Ideally, the vinyl decks would have a built-in low-pass filter too, but it really doesn't matter because most amps (and speakers) will filter that too.
      The low-pass on a CD is basically just the digital version of that. :p
      It's also necessary for filtering out the unwanted "mirror" images of the normal 20KHz audible range, otherwise it could introduce unwanted noise.

      CDs do have limitations. They are forever stuck with 1982 technology. 16-bit digital is noisy and the 44.1 kHz sampling rate requires a steep brickwall filter to prevent aliasing. Over the years the industry has come up with various "Band-Aid" fixes to alleviate these problems, such as dithering, noise shaping, oversampling, and HDCD, but it's still not perfect.
      Today there is no reason why we shouldn't be offering 24-bit 96 kHz digital audio directly to the consumer, because these days any computer, smartphone, or iPod is more than powerful enough to play it, but we're still stuck with the same old 16-bit 44.1 kHz standard from 1982, now made even worse with lossy AAC or MP3 encoding (itself forever stuck with antiquated 1994 technology).

    • @electronash
      @electronash 7 лет назад +5

      I completely agree. ;)
      44.1 KHz was enough for the audible spectrum, but that of course could always be improved so the noise is way lower and there is less aliasing / mirroring.
      I don't really download much music any more, but last time I did it was FLAC (96/24 where possible).

    I very much agree with your findings and I have for years. I remember being a small child in the mid 80's when Wal-Mart took out the vinyl section. Sad day that way LOL However, I think that a big thing a lot of people fail to remember, let alone know, is that sound and music, which we enjoy, all has harmonics. I noticed for the spectrum analyzer you had going of these recordings, the amount of higher end harmonics that get lost in the CD quality digital recordings. When I played back the early 70's analog recording of the synthesizer, you provided, the sound was more full bodied. It's 'easier' on the ear, is the best way to describe it Like that sneeze that almost get there, but then vanishes, leaving you unfulfilled, is the best way to describe the difference between the old analog and newer digital sample rates (referring to CDs).

      Look up the Shannon-Nyquist sampling theorem; the harmonics that get lost with the sampling rate of a CD (44.1kHz) are somewhat lower than half its sampling rate, because of low pass filtering to prevent aliasing, about 20kHz. So unless you can hear sounds above about 20kHz the limited sampling rate and therefore the "lost" harmonics of a CD recording are irrelevant

    It certainly looks like the higher frequency data is coming through on vinyl. I imagine, depending on everything else in your chain (phono amp, power amp, speakers) the higher frequency data will "sound" different due to harmonics. I think this is why various hack-fixes have been attempted to the CD audio format to improve its performance relative to analog sources. CD audio was a product of the digital electronics of its time. They weren't that good.

Not many instruments even go to 10k.

    • @MiguelCatalaoMusic
      @MiguelCatalaoMusic 6 лет назад +3

      While i agree with you on the discussion issue, an instrument goes to much more than 10k, since depending on the complexity of it's sound, it will create an infinite sum of harmonics, the harmonic series. This harmonic series, will have different intensities for each n making up the instrument timbre. Point is, we don't hear beyond a given number of harmonics that are in the perceived frequency range and it's true that we don't perceive tone for well, most of what is upper hearing (this might be related to our hearing evolution being very related to the human voice). There are also the inharmonic components, like ringing, or other aspects of the instrument that make up it's sound. Still, saying most instruments don't go upper than 10 kHz is reductive, or music would only be made of 10 kHz representations, and music is full up to at least 16 kHz spectrum. It's unfortunate you are on your 30's and don't hear from 12 kHz up, but there's still a lot of content from 10 kHz up.

Vocals also have a bunch of different components, depending on the mouth format generating comb filtering to form vowels, and different kinds of transients and sibiliants to form consonants .

    Quadraphonic LPs (CD4 format) of the early 70s relied on a sub-carrier frequency of 30khz to carry the extra 2 channels - much like music broadcast on a FM carrier. There is no doubt frequencies above 20khz can be cut into vinyl but in the case of CD4 - no one reported hearing it. Some of pointed out resonances in your cartridge may make it look like their is more music information above 20k as might digital specific distortions such as jitter in the ADC in your sound card.

      (neé Cool Edit Pro... really should pick it up myself one day, given that I really don't get on with Audacity and found CE's interface much more intuitive. Plus of course it has that nifty live spectrograph, which Audacity still doesn't have even in 2018 despite Cool Edit having it way back in at least the '96 version if not earlier... good to see that the live mode has been extended from 2048-band to at least 8192-band FFT though... that's probably about the limit for reasonable update speed, though. And really it's a bit pointless going that high with the linear chart, as you haven't that many pixels; 2048 would be perfectly good in this case and give a faster update speed (it's not that the computer can't handle it, it's just that the timebase for the analysis is smeared out over a great many more samples; 120,000 / 8192 is effectively a little under 15fps, whereas 2048 would be almost 60fps) without losing any visible resolution. Whereas 8192 would be much better for a log-scaled chart, retaining more resolution at the low frequency end that gets magnified in that view)
      Just a thought, have you considered showing the difference using the actual spectrogram display for the whole wave? That can show up just how much high frequency content is present, and how finely tuned it is, probably even better than the live line-chart can. And of course you can put two versions of the same recording side by side, one digital and one analogue, to show how things differ both above and below the cutoff :)
      Though of course its resolution is a bit more compromised than the live chart, because you have to fit two channels in sight, vertically stacked, within your vertical screen resolution, so anything beyond 512 bands will probably be a waste, whereas the live chart can almost show the full resolution of a 2048-band FFT horizontally, with both channels overlaid on each other... (assuming 1920x1080 pixels in both cases). Still, it can be worth it to see a lot more *time* all at once (one second, or one hour... whatever you feel like), rather than a series of 1/15th of a second snatches one after the other.

    I think someone should compare the frequency response of the vinyl, and master tape that the vinyl was produced from, and compare. Digitize each one at 96kHz/16-bit (24-bit is pointless) and compare. I have some modern SACD remasters of old analog recordings, and there's really nothing above 25-27kHz. Maybe 28-29kHz. And into the 40kHz range it's just noise. Now, I read this is because of DSD being different than standard PCM, but there's nothing up there. It would also be a good thing to see how an album that was digitally recorded at 96kHz looks like on vinyl compared to the master recording.

  • @deodatocosta8172
    @deodatocosta8172 7 лет назад +1

    Most Audiofiles believe that analog is better because it is "infinite" when it's actually not it's still subject to bandwidth size and other issues but it does not have a fixed bit depth while most digital recordings are made in 16bit depth which is a bit low probably because it was more economical at the time.I personally think they should have chosen 20bits as standard resolution increasing 4bits doesn't sound like much but the bit depth is increased by a whopping 1500% without taking up much more space.

      I'm one of those audiophile, musician and home recording studio types that agrees with what the science is telling us, e.g. that digital is more capable and that what is input is generally outputted the same etc, but I happen to have a preference for the sound of analogue tape and vinyl because to my ears it sounds and feels more musically pleasing. So when I say analogue is better than digital, it is meant in the context of preference rather than scientific fact.

  • @decnet100

    Coincidentially, what's the total harmonic distortion of a typical vinyl system? I've seen measurements higher than 1% (-40dB) even on decent quality equipment, most of it being introduced during the cutting and playback process. So for a high frequency event such as a cymbal hit, you automatically receive several higher frequency signals, which I think is what's going on during the"from digital" recording - even if the master contained no information whatsoever beyond 22kHz, the vinyl cutting and playback process will result in some high frequency content that is simply unintentional and probably wasn't even present in the original music. If we're talking single note signals such as those analog synths, that sort of high-frequency content is not too much of a problem since nobody can hear it anyway (and a square wave synth will even create it's own infinite harmonics), but as soon as you're running into several notes and harmonics getting played simultaneously, you also run into intermodulation distortion, and that's a very audible phenomenon. Maybe some people like certain aspects of it, I personally prefer not to have it in my music.

  • @elahuigmail
    @elahuigmail 7 лет назад +12

    The problem with vynil has never been frequency response; the issue is the S/N ratio. If at 40 khz you only get 20dB tops, then whats the use. Even in the hearing range Vynil has low S/N ratio. For analog resolution and S/N it's better to use a 2 inch magnetic tape at 30 ips. Just my opinion.

    • @nathan43082
      @nathan43082 7 лет назад +3

      A 2-inch magnetic tape at 30 ips-even with noise reduction-is never going to match just 16-bit digital let alone 24-bit digital.

    • @mspenrice
      @mspenrice 6 лет назад

      I don't see how that could be the case. If anything I'd expect it to lose some bass power. Are you sure you don't mean 7.5ips, rather then 30?
      As for SNR, it seemed to be thought acceptable to use as a master including for CDs for a good long time, and seemed to have a perfectly fine noise floor (it's what would be used as the master for some of the old vinyls shown here, and they look to have a noise level comparable to CD, ie the graph tails off to less than -96db). And generally even on fully digital CDs, you're not really getting much more than 20db SNR at the higher frequencies, if you look on a spectrogram. It's now much the active frequencies add up vs the noise that's more important than the SNR of any given frequency (which simply sets about how loud it sounds... you can't have everything at 0db or even -6db, it'd be a total racket). That's the reason the floor needs to be set so low, well beyond the realm of hearing, so that even quiet sounds can come through in a legible way... 16-bit is fine for that, 12-bit is sketchy, 8-bit is hopeless and rather like a low quality ferric compact cassette, except with the added fun of the noise being the digital quantisation type rather than the softer analogue type where you can still pick out some subtle sounds through the hiss at -45db instead of them being lost to the scratchiness down at the least significant bit level.
      Or let's put it another way... I used to have to do a lot of academic lecture-capture voice recordings, and background noise was always the enemy (projector and PC fans, outside noises if the sound insulation was imperfect, plus a hundred or more people breathing, coughing, muttering, moving papers around etc). Between trying to get the best mic setup, encouraging speakers to shout rather than whisper, and using as much digital noise filtering as I dared in post editing, it generally came out that about 20db is your limit for being able to produce an end product that sounds OK... 10-12db is the limit of being at all decipherable... and with anything over 30db you're good to go with hardly any editing at all - and that's the whole-spectrum intensity, not just a single band (which could often be as marginal as 6db and still be recoverable with only minor artefacts with a good noise reduction algorithm). So a single frequency band within a music recording having 20db SNR as-is should be fine... it would be like it being no quieter than about -27db on a cassette, and I'd bet if you had a piece of music with all its elements being that intensity or louder you wouldn't be able to make out the hiss (I figure anyone who says they can tell something's recorded on tape from listening to a full volume section, rather than a quiet intro or fade out, is probably lying; the entire foundation of mpeg audio encoding is based on psychoacoustic modelling of how the human auditory system automatically tunes out quiet noise in the presence of loud sounds after all).
      Besides, anything that's been subject to modern production methods probably doesn't even have that much dynamic range full stop... Everything's crammed into about the top 12db. :-/

      The thing is if you listen to a real band play you will hear background noise from people at the venue. moving, talking etc. No one complains about that. In a way vinyl is more like the real world where there is always background noise present. CD's sound artificial to me.

  • @nathan43082
    @nathan43082 7 лет назад +2

    So is your argument that vinyl is capable of preserving content upwards of 50k or that the content up there is in any way meaningful? The CD4 quad system relied on 45 kHz bandwidth to be accurately reproduced, but that was to embed an extra two channels’ worth of information. Most recordings don’t have any content above the range of human hearing, so attempting to preserve it seems pointless in most cases, at least when it comes to the final delivery mechanism. While vinyl *can* hold a very high frequency, it won’t do so for long due to wear and that high frequency is not going to be heard by anyone with human ears.

    • @vwestlife
      @vwestlife  7 лет назад +3

      Wrong. Lou Dorren, developer of the CD-4 format, did tests of playing a CD-4-encoded LP 500 times on a cheap record player with a ceramic cartridge and conical stylus tracking at 4.5 grams, and after cleaning the record, it played and decoded perfectly on a CD-4-equipped turntable: www.amstereo.org/files/cd-4paper4.pdf

    • @nathan43082

      Okay, for argument’s sake, let’s assume that this is true. So what? Why use vinyl? I can play a digital recording one million times and it never loses even 0.000001% of quality.
      There are no upsides to vinyl from a technical standpoint-digital can hold much more information if you want and more accurately to boot-and there are only downsides, unless you are in it for the nostalgia, the ritual, the album art, etc. One might argue that we should all go back to wire recorders or wax cylinders because older is somehow better.

      Not necessarily.

    I thought that stylus could only capture up to about 28k or something, and also human hearing stops at around 21khz, so all that musical information that your spectrograph shows, in the 30-60k range, isn't really there, it's just how your dac resolves it, its not real. Try to solo that range, if you have the means to (a highpass filter plugin) and set the filter to 30k/96db slope or brickwall. That means you will only hear that above 30k. I'm 100% positive you will hear ALOT even though that's impossible to do. Your vid is a very flawed representation of what is happening

    I think the vibrating needle acts like a pendulum and does not immediately stop at the end of a note.
