Digital and Analog Audio's Curious Coexistence (cnet.com) 345

Steve Guttenberg, writing for CNET: It's a funny thing, the ongoing turntable sales surge shows no signs of slowing down, but nearly all new music is recorded digitally. It seems like a contradiction, turntables and LPs are purely analog in nature, but nearly all new (not remastered LPs) made over the last 30+ years were recorded, mixed, and mastered from digital sources. Older, pre 1980 LPs were made in an all-analog world. Today's LPs are hybrids of a sort, the grooves are still analog, but the music was probably made in the digital domain.

Be that as it may, LPs, regardless of vintage, can sound great. While pre-1980s records may be richer in tone and warmth, there are lots of more recent albums that sound just as good or better. In other words vinyl's sound quality or lack thereof has mostly to do with the quality of the original recording, and the choices made by the recording, mixing, and mastering engineers.

Despite the overwhelming number of digital recordings, there is still a tiny percentage of all-analog recordings being made. To cite one mostly analog studio, the legendary Electrical Audio, which owner Steve Albini told me records and mixes around 70 percent of all of its sessions on tape.

    No, if everything comes from the same digital master, then vinyl's difference in sound quality comes from imperfections in the medium itself.

      It's a bit of both. A regular 44khz audio CD can't capture the full resolution of a digital master done at e.g 96khz. But imperfections in the medium are more likely to cause differences you can actually hear.

            The 44kHz CD can exactly reproduce all the waveforms in the 96kHz source, provided they are below 22 kHz. The analog vinyl can reproduce some waveforms over 22 kHz, but introduces distortion over the entire frequency spectrum.

            Over the part that we can hear, the 44 kHz CD is more faithful to the original than vinyl. In either case, the differences are not due to the source material.

            Also, none of the components in the sound system, such as filters, amplifiers, and microphones are designed to operate properly at ultrasonic frequencies.

                I took a course in audio engineering in the late 90s. I would like to have had the world settled on 48kHz and 20-bit for listening. 96kHz 24-bit for mastering is just fine. 44.1/16 was a good technical compromise for 1980 and superior in almost every way to vinyl, epically in the reproducibility department.

                That being said, my ears do like Blu-Ray audio a lot. But my CD collection isn't going anywhere. My vinyl collection was liquidated in the 90s and I do not miss it. Though I do miss my record player and old 60s "HiFi" for sentimental tactile reasons.

                All analog systems had filters and bias compensating EQs built in. From the late 70s on these were ALL digital. So even people thinking their tape master was Analog were wrong. All tape has a bias and must be compensated for. The main difference to me in recording is clipping, digital clips horribly and analog sometimes sounds good when it clips. This is not an accurate reproduction of the sound, but so many people think it is. If you want this effect, you can do it in the studio with digital.

                Most consumer audio systems can't reproduce anything beyond 18kHz or below 20Hz. That is probably a good thing to protect the speakers from over heating their coils due to long tones playing that no one bothers to listen for. But I do miss overtones in violins and wind instruments. I had documented ability to hear 24kHz when I was 20. I was the only one in the class. I could also hear and transcribe accurately conversation and test tones at SPL levels most people couldn't distinguish from background noise. Now I don't think I can hear past 19kHz. But I am very sensitive to 16-17 for some reason and am still Radar O'Rielly when it comes to hearing things way before others (and some dogs) do.

                So, if you want to better replicate the entire experience of GOOD human hearing, boost the dynamic range to 20-bit and extend out to 10Hz-24KHz, with Nyquist this means 48kHz sampling playback. Whether anyone but one in a million will notice is another question. So thus, contentment with redbook 44.1/16.

                Note: a properly mastered CD should sound great at 16-bit, giving around 60dB dynamic range. An orchestra has considerably more dynamic range, but usually not in the same passage. So if you master correctly, 16-bit listening should be enough... but I'm anal and would like loud-soft transitions to be done more natural. For recording and mastering 24-bit is a major plus. Aliasing is a bitch. Most pop songs could probably be listened to in 10-bit without any noticeable difference. Too much compression.

                    I agree, it is distortion, but then again so is the clipping. It's digital aliasing, a sampling error due to the signal being beyond the maximum range of the digital representation.

                    So actually the smoothing that vinyl/valves produces could reduce the amount of error through a kind of anti-aliasing, similar to anti-aliasing that some DACs use. It can seem counter-intuitive, but adding a certain amount of noise is a common way to reduce overall error.

        For me, personally, put the vinyl mix on a CD and it'd settle it pretty decisively. Most CD recordings are way overcompressed and I do like me some dynamic range.

    • There's a big difference between fidelity and quality. Sometimes the distortion introduced by a medium or by processing can make the music sound better, even if it is also less like the original.

      Plus the vinyl version often has a slightly different mix than the CD version - it's not even the same song.

    • Or, "digital" doesn't offer enough information in order to make an accurate assessment of what's going on. For example: I'm no sound engineer, but I'm guessing the studio has far higher quality equipment using far higher sampling rates and bit depth per sample than standard 44khz PCM. Once the master is made in the much higher quality, it's then downsampled to the CD audio and digital files distributed to iTunes / Google Play / Pandora / Spotify / Amazon / Whoever.

    • by AmiMoJo ( 196126 )

      You are both rights.

      The original master is often made with CDs in mind. CDs have more dynamic range than vinyl, and can have more loudness enhancement applied. If your recording is too loud the needle will skip out of the track on a vinyl record, so lazy sound engineers just apply some filtering and send the file off to be duplicated.

      Good engineers do a proper re-mixing of the source material, which often ends up with the vinyl release sounding better because it is less compressed and more dynamic.

      In theory yes, but in practice CDs are capable of reproducing very highly compressed audio that would make the needle jump on vinyl. So the CD ends up being far more compressed than the vinyl release, and the vinyl sounds more dynamic.

      Sometimes the digital master for the vinyl version leaks out, and is highly prized by fans. Sometimes the Japanese special editions have less compression too, because for some reason that market prefers it or is more willing to buy re-masters.

  • The obsession with analog audio stems from a gross misunderstanding of what digital audio is. People see digital sampling as a partial capture of the analog waveform, and thus conclude analog must be superior. Digital sampling is not a partial capture. It's an exact capture of the analog waveform within the frequency range (22 kHz in most cases - well beyond what most people can hear). The part that's not intuitively obvious which trips most people up is that if you take a digital sample of an analog waveform, there is only one possible analog waveform which passes through all those digital samples while not exceeding the frequency cutoff. So the digital sample ends up being a perfect reproduction of the analog waveform (within the frequency range of interest).

    You can demonstrate this by taking an analog waveform, feeding it into a digital sampler, then converting that digital sample back into an analog waveform. The beginning and ending waveforms will be identical [youtube.com] despite the latter one having been converted to digital and back to analog.

    All the "warmth" and "richness" of analog audio is nothing more than distortion.

  • The real points here are not with the recorded sound quality, but with the listened sound quality.
    If you insist in using earpieces, noisy environments, low attention and MP3-like sources, the vinyl ain't any better than a 192 kHz MP3. And it loses quality play after play.
    If you instead use high end speakers in adequately insulated rooms and keep your attention to the sounds you're are listening to, than maybe the first plays on a vinyl will make some difference.

    Aside from the only truly valid reason to own a turntable, which is, 90+ % of all the music produced prior to about 1990 will never be released in a digital format ... in other words it's about the software, not the hardware. It is the fundamental reason for owning a vinyl playback system, or a cassette deck for that matter. All this hardware talk is just noise. Sure, some people want better playback of these analog formats, but focusing on that is a huge Red Herring. For some reason Tech writers can't get past a focus on hardware, and that goes for digital as well as analog audio.

    But, we live in an analog world when it comes to music. It starts analog, and it ends analog (playback). A very, very long time ago I learned that with electronics, every time you make a translation ... whether that's simply recording live to tape or Digital Audio Workstation, or a change in format, or any number of ways to do a job with the electronics ... and there is always the final translation to moving air in a room, you lose something. Maybe not much, but something.

    The other thing is you use the best tools for the job. Recording on a DAW is better than recording on magnetic tape, the only real viable alternative option. Yes, you can record direct to (vinyl) disk, but that's hard and doesn't lend itself to large quantity replication, so it's a niche example. It is better than mag tape, but it's also severely limiting, an "old-school" technique, live to final mix, that was happily abandoned when multitrack recording technology came along.

    So, whatever tools were used to *create* an album, when it's final form is finished, that's your product. It doesn't matter if it was recorded, mixed and mastered on a DAW anymore than it matters that the artist used a toy piano or a concert grand to make the music. Once in finished form, then it matters how it's played back, because a vinyl record doesn't sound like a CD, and it shouldn't sound like a CD, otherwise there is something seriously wrong going on (with the CD, probably).

    So, a phono cartridge is a transducer. Like a dynamic microphone, like a loudspeaker. What distinguishes transducers from other parts of the playback chain is they are not powered devices. A phono cartridge has no power supply, it generates it's own voltage through movement. If you push on the cone of your subwoofer, it generates a back-electromagnetic force on the power amp. And so on.

    And although it's not obvious to most people, when you listen to music through a modern sound system, you are listening to the power supply, modulated by a music signal. So the quality of the power supply is paramount to the sonics.

    CD player? Power Supply modulated by a music signal.
    Amplification? Power Supply modulated by a music signal.

    But not a phono cartridge. There is a vast array of issues to deal with when you have to use a power supply driven by mains current from the wall. It would not be an exaggeration to say that almost everything in audio that has developed since the early 20th century is the story of power supply technology and ways to modulate that supply.

    So, it would be unusual if vinyl *didn't* sound different, even if the final product (the shipping software, in LP or CD or whatever form) was created exactly the same way.

    Not audiophiles but Nyquist deniers !

    People on here who say something is lost really really haven't read up to Nyquist or watch the excellent
    "D/A and A/D | Digital Show and Tell" video on YouTube.

    They are true science deniers. They say it's better but can point to no measurement of why this is. The best they can come out with is frequencies above 22KHz, which are likely noise and even if not, most cutting heads cut ultrasonics to avoid overheating the cutting head anyway. Yet they still claim their medium that is crackles, gets worn out, is likely mono at low frequencies to avoid the needle jumping out of the groove (above the subwoofer cut off frequency) is better.

    A few reasons to like vinyl, the art work, avoiding the loudness war and nostalgia. Best to digitise vinyl of first play and never play again, this digital recording will always be the best one.

    The analog is always better people need to ask themselves, so why is our DNA is digital, simple, to maintain fidelity across copies.

      Yup, this is what annoys me the most about most of the vinyl crowd. It really wouldn't bother me if most of 'em understood that their format was shit, but as a matter of personal preference they still preferred it. However, there's almost always this insistence that science is wrong, "vinyl is a superior audio reproduction medium!"

      The primary reason it was popular in its heyday was that vinyl was easy and cheap to mass produce, making it an ideal high-profit format for distribution and sales of music. Ev

    • Keep in mind music is recorded to sound best in the media it's going to be distributed in. The ambience of the media is factored into the production, whether intentionally or not.

      If you play an old 78 from the 1920's on a modern turntable with modern amplification, it sounds like someone is frying an egg in the background, because modern equipment can pick up the defects in the media.

      If you play it on 1920's Victrola, it'll actually sound pretty decent, because the acoustic reproduction equipment is incapab

      • The are several reasons why a 78 will sound bad on a modern turntable. First you need a different needle for 78s. Secondly back then the speed at which the record was cut could fluctuate a lot between manufacturers so you need more leeway on adjusting the rotation speed. Third the RIAA equalization curve is different or non existent for 78s so yeah it's going to sound bad. Go on YouTube to hear some properly played 78 records.

    • Nyquist isn't the whole story about digital audio, though in practice it's a major argument. When you look at the math of the Nyquist limit, it assumes a few things that don't hold precisely in real life. One of the real-life issues is quantization error, which is kind of obvious: higher bit depth per sample is better. If you use 1-bit sampling at 44.1 kHz, it'll probably sound horrible.

      The subtler issue about quantization error is that it's not a random error. So adding a bit of analog noise at levels u
