The Rise of "Hybrid" Vinyl-MP3s

Khyber writes to let us know that First Word Records, a U.K.-based record label, is now selling vinyl records that come with codes that allow you to download a 320-kbit MP3 of that record's content. The article mentions another independent label, Saddle Creek, that also offers DRM-free downloads with some vinyl records. The co-founder of First Word is quoted on why they didn't DRM the download: "Making a legal, paid-for version of the file less useful than a copied or pirated one doesn't make sense."

      My understanding is that CDs go up to 20 kHz ... but that the bit-depth is somewhat course at that range.

      You are probably thinking of 'one-bit' (or bitstream) digital to analogue converters. (Wikipedia article.) It gets around the problem of producing 16 bits of resolution with a single bit by switching at a frequency many times that of the sampling frequency and averaging over time.

      In its purest form, it would switch at 2^16, or 65536 times the CD sample frequency. If one CD sample value is 0, the DAC would be off for 65536 DAC output samples. If the CD sample value is 65535 it is on for 65536 DAC output samples. For intermediate values it is on for the given proportion of the time. In other words, the CD sample value determines the duty-cycle of the output from the DAC. The one-bit on/off output is then averaged over time. This results in a conversion with almost no non-linear distortion of the signal.

      Unfortunately a frequency of 65536 * 44.1 kHz would be in the THz range, so the actual frequency that a 1 bit DAC operates at is somewhat lower. For lower frequency audio signals the averaging process is still very accurate, but it loses some accuracy for the highest frequency audio tones mostly when there are rapid transients in the high frequencies. You might refer to this as a 'coarsening of the bit-depth'.

      A full 16-bit DAC doesn't suffer from this problem because each sample from the CD is converted straight into a voltage proportional to that sample value in a single step. But it is very difficult to make a completely linear 16-bit DAC, so the non-lineararity of the DAC introduces its own distortions. But these distortions do not depend on frequency as they do with a 1-bit DAC.

      Yes. Nyquist. There's a Theorem, a Limit, and a Guy that discovered these, all by the same name.

Humans can focus on any part of the audible spectrum, but voices won't typically fall outside the 300-3300 Hz range. Thus aLaw (US) and mu-Law (outside the US, a.k.a. "uLaw", since the Greek mu looks like a u with a tail) are typically 8000 Hz sample rate, 8-bit-sample, monophonic (who has a stereo telephone?) signal when digitized.

      The GP was worried that the bit depth is "coarse". This is not the case. Bit depth "distance" is constant for a given depth.

      CD's are 44.1kHz, 16-bit, stereo. Always. So there are always 44100 samples per second per channel. There are always two channels (stereo, one left, one right). And each sample in each channel is always 16 bits. A 16-bit integer can represent numbers from 0-65535 (2^0-1 through 2^16-1), and since there's no need for negative numbers (this is Pulse Code Modulation, or PCM, so no, you don't need to represent a +/- of a waveform) you get the full 0-65535 swing. From there, the value is directly translatable into a DC voltage that goes to the speakers. (Most of the heavy lifting is done in the A/D phase, D/A phase is a simple value-to-DC conversion.) The change in DC voltage over time is what causes the magnets to move, which moves the speaker cones, which moves air, which moves your tympanic membrane, which blah-blah-blah... eventually you hear sound.

      So there's no need to worry. Nothing gets coarse. Nothing loses fidelity. Nothing loses audible quality. This is why vinyl fanatics get laughed at by people who know how and why digital audio works. The limits of even now-mundane CD audio are far above the possible limits of even hypothetically perfect human hearing. Nobody can hear 22kHz. Nothing below 22kHz is misrepresented in CD-quality audio. For mastering work, where effects will be applied later, higher quality recordings are wonderful, since you can guarantee that it will stay high-quality when downsampled to CD-quality, but other than that (and "economies of scale" where better parts are just as cheap to produce), there's no need for anything better.

      Look, if you're going to make up justifications for using vinyl, make them more convincing. Much of the theory about human hearing is based on the assumption that the ear acts as a linear system. If the ear were a linear system there is no way it'd be possible for "certain confluences of sound react with each other and produce further sounds". In linear systems harmonics at different frequencies simply add, there is no possible 'interaction' that can happen between them.

      But nonlinear systems are quite different. The classic example is soliton waves. When two of these meet, they don't simply combine additively. In particular, different harmonics don't necessarily pass straight through each other and its quite possible for two very high frequency signals to interact and produce a low frequency signal in the result. And of course there really is no reason to expect the ear to remain close to a linear system, even ordinary sound waves in air become nonlinear if the sound is loud enough.

      So if you want to sound convincing, talking about nonlinearity is your best bet. I can guarantee that 90% of the engineers you talk to won't have a sensible response because they've never studied nonlinear signal processing, and they'll be less likely to laugh at you.

      Modern digital equipment sounds far better than it should because of the tricks employed in the converters. Oversampling and noise dithering has a massive effect on the sound, and you aren't really hearing the true digital signal but a smoothed one. Before such techniques were used, digital equipment got huge criticism for being clinical sounding (quite rightly). Vinyl and other analogue systems don't have this problem obviously, but bring loads of others to the table (wear and tear, damage, static, etc).

      For some material, 16bit is definitely not enough. It's fine for a lot of modern chart material, where the mastering has multiband compressed it to hell and back to make it sound louder than the competition, but those tracks don't need the dynamic range of a Chopin valse, or a Beethoven symphony. The quiet bits on 16 bit recordings definitely lose a lot compared to 24bit (side by side comparison using old and new gear) - but I think it is really the recording and production stages that need 24bit or more, not necessarily replay because of the tricks that can now be applied.

Since that is less "natural" than a good stylus / magnetic cartridge, it implies design desicions, which are most certainly not tailored for my taste. Most CD players focus on harmonics and fidelity in the higher ranges of sound (above 500 Hz) to improve quality while listening classical music or non-distorted pop / dance.

    There are no such thing as analog values in this universe, everything is quantized. You cannot possibly have an electric signal that's totally free of noise, what you get is a number of "clicks", one for each electron that goes by.

    Now, I know people will say, "sure, but these effects are very small". Well, think again. Human hearing evolved to be as sensitive as it physically could be. Inside an anechoic chamber you can hear the blood flowing through your veins. The sensitivity of our ears is just short from hearing individual molecules hitting the eardrum. In any analog pick-up, be it moving coil or moving magnet, human ears are sensitive enough to hear the noise due to the quantization of electric current.


    Digital equipment have much better signal-to-noise rations because they have high currents in low-impedance circuits, the effect of charge quantization is diluted by averaging a large number of electrons. In analog vinil pick-ups either the impedance is relatively high for moving magnet models or the voltage is very low for moving coil types.


    And all this is considering only the most fundamental effects, not to mention problems as dust on the record. The cleanest cleanroom specified in the ISO-14644 standard has 12 particles per cubic meter. The lowest spec in ISO-14644 allows over 40 million particles per cubic meter. Does the room where you do your listening conform to an ISO "cleanroom" specification?


    Digital sound standards were created to be as good as they need to be. CDs have all the bandwidth and dynamic range one needs in the final recording. It's only when you are going to mix and resample the music that you may need better quality to avoid round-off error in the processing.

  16. The REAL reason behind 44.1 kHz by darkain · · Score: 4, Informative

    http://en.wikipedia.org/wiki/CD#Audio_format

    "The sampling rate of 44.1 kHz is inherited from a method of converting digital audio into an analog video signal for storage on video tape, which was the most affordable way to get the data from the recording studio to the CD manufacturer at the time the CD specification was being developed. A device that turns an analog audio signal into PCM audio, which in turn is changed into an analog video signal is called a PCM adaptor. This technology could store six samples (three samples per each stereo channel) in a single horizontal line. A standard NTSC video signal has 245 usable lines per field, and 59.94 fields/s, which works out at 44,056 samples/s/stereo channel. Similarly, PAL has 294 lines and 50 fields, which gives 44,100 samples/s/stereo channel. This system could either store 14-bit samples with some error correction, or 16-bit samples with almost no error correction."

  17. Wish I could mod that up... by Valtor · · Score: 2, Insightful

    Making a legal, paid-for version of the file less useful than a copied or pirated one doesn't make sense. It is a pity we can't mod that +5 insightful for the other guys in that industry...

  18. Not a True Hybrid by PPH · · Score: 2, Funny
    Its not a true hybrid until they figure out a way to get MP3s to skip and warp if you leave them in a hot car.

    They do have MP3 turntables you can use to 'scratch' recordings.

  19. 'digital' vinyl by hack++slash · · Score: 2, Interesting

    When I first saw the heading I thought the mp3s were stored on the actual vinyl and wondered how they'd be retreived from them, nothing so fancy but it reminded me of the plastic flexi-disc I have stored away with my miniscule vinyl collection, the flexi-disc in question having a couple of Sinclair ZX81 programs on them whereby you use a turntable instead of a tape recorder to load the programs in.

  20. Hmm... by Ayanami+Rei · · Score: 2, Interesting

    I think it's disingenious to talk about air as a non-linear system. It doesn't start acting non-linear until you're talking about distances (and/or/which imply) amplitudes that would shatter your eardrums or kill you.

    I mean, let's talk about the non-linearity of speakers! They're damped oscillators!

    And you can prove to an audiophile (hearing is believing) that sound is sufficiently linear to make such arguments irrelevant.

    Take two frequencies (say... 14000 and 14300). If you play them, you get a 300Hz beat. Put that on one channel. Now take a 300Hz sine on the other channel, and then adjust the phase slowly. You should "hear" the 300Hz tone moving around the sound stage.

    This experiment only works because sound reproduction (and your ears/brain) are a sufficiently linear system that trying to call it anything else when making qualitative arguments is just silly.

  21. What's the point? by Daishiman · · Score: 2, Interesting

    What's the point of a vinyl of a digital master?

    As I've mentioned on a previous thread, I'm a huge fan of classical jazz and I have invested very seriously on a pile of records from the time, and I'm of the opinion that mastering was done more carefully back then and made to sound well with the way vinyl colors the sound.

    But sheesh, if you're going to master an album digitally then why add noise of the line by converting it to a physical medium with a low S/N ratio?
