Records are big, fragile, unwieldy, and generally inconvenient. Digital alternatives like MP3s and CDs are, on the other hand, small, portable, durable, easily reproducible, and generally convenient. Plus, you look totally trendy with your iPod (keep telling yourself that). So, why would anyone bother with vinyl? Why not melt all your records down into some kind of crazy sculpture?

Digital vs. Analog Sound

Any good vinylholic will tell you that analog recordings sound better than digital ones. In principle, this is true - provided you take care of your equipment and clean your records.

What Is Sound?

Sound, as you hear it, is analog by definition. It's a waveform [fig. 1] that hits your ear, vibrating the eardrum. Any analog recording - a vinyl record, for instance - duplicates the waveform of the sound that was recorded in full. Every point on the wave, of which there are infinitely many, is reproduced by the analog recording.

Digitizing a Sound

A digital recording samples a certain finite number of the infinite points to reproduce a likeness of the original (analog) sound [Fig. 2]. There are plenty of reasons to do this. Most notably, the amount of information involved is much smaller, so it's easier to manipulate, store, transfer, etc.

However, no matter how good your sample, it will always be missing some data points, and this will (theoretically) always affect the sound. The human ear's ability to distinguish is finite, and at a certain point a digital recording will sound indistinguishable from the analog version, but the level of sampling fidelity required for this is so high that it eliminates most of the aforementioned benefits of digitization.

Compression

In order to produce a digital sound that isn't totally unlistenable, you need to have a pretty large file. Rais your hand if you store your music in .wav format. Nobody? Hmm...

The reason, of course, is compression. There is a veritable cornucopia of competing data compression formats, and different ones are best for different applications. Compressing data, in short, allows you to produce those nice, compact audio files, so you can have a dozen albums on an MP3-CD in your car instead of one on a conventional audio CD (which is uncompressed).

You hear a lot about "lossless" audio compression (the FLAC format, for instance) these days. A lot of people think that this sort of file hasn't lost any fidelity from the original recording (as opposed to an MP3, which is a "lossy" compression format) - but that's not true. What "lossless" means in this context is that no fidelity has been lost from the uncompressed digital recording, so your FLAC file still might not sound as good as an analog track.

Recap: The Bottom Line

All other things being equal, a digital recording typically doesn't sound as good as an analog recording because parts of the sound are always missing.

Still with me? Good.

The Listening Experience

This is where I get all philosophical. Hang in there.

I've alluded elsewhere to the powerful aesthetic vinyl holds for the true enthusiast. There's something ritualistic - religious, almost - about sliding a treasured LP out of its jacket, laying it on the platter, dropping the needle, and just listening.

Listening to an LP is an active experience [Fig. 3] that simply can't be duplicated. Don't get me wrong: I own an iPod, and use it extensively. But beyond the pure sound of a properly cared-for record on a high-quality sound system, the reward to be had from being present in the moment, engaged with the music, is very real and very powerful indeed.

So, what are you waiting for? Dust off the old LPs and get cracking!

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

That's hot.

I've made a deal with myself that anything I think I might want to still listen to in ten years (for reasons other than nostalgia), I'll get on vinyl. Music is personal, and analog formats are tactile and, well, personal.

Evan... you are a legend! You have totally inspired me and I am, as I write, cracking out my vinyl and contemplating a trip to the markets and my fav second hand store to purchase some more. I prefer buying LPs recorded when vinyl was king, something about the sound and the look that can't be matched by cd recordings of the same records or even LPs made in the CD age.

I am also a huge fan of both the tactile and aesthetic qualities that vinyl has (I do include cds in this but I suspect I am not so much a purist as you are). While I have an ipod for mobile convenience I NEVER listen to music on my computer or use my pod at home. I will always and forever love the jacket, the liner notes, the tangibilty of a record... *sigh*

Thanks, NewsFlake, for your kind words.

As for being a purist, this is something that I've always felt conflicted about. On the one hand, I absolutely love vinyl: I love the liner notes, the album art, the feel, the smell... I love flipping through crates of records and unearthing hidden gems.

On the other hand, I love what easily-produced digital music is doing to distribution.

I suppose it all comes down to this: music is digitizing, and vinyl is slowly fading. So cherish what you have, try to get your hands on more before it disappears, and embrace the best of what's new!

Thanks for reading.

    I remember the whole cd-versus-vinyl debate and later the mp3-versus-cd debate. During the cd-versus-vinyl debate I was working at a radio station and all of us were of the opinion that vinyl was better. Most of us on-air dj's used vinyl in our shows but there were a few who chose to use cd's. My opinion at the time was that we owed our listeners the best sound reproduction that we could put out, and that was vinyl.

    I suppose it all comes down to this: music is digitizing, and vinyl is slowly fading.

    I suppose in some ways you're right, but the fading varies by relative genre. In the hip-hop world there is still a lot of vinyl being produced for the DJs. Also, more and more "indie" rock artists are coming out with vinyl versions of their CDs, becuase audiophile hipsters have all stolen their parent's (or, for even greater cred, their grandparent's) turntables, but don't really dig all the Burt Bacharach and Grateful Dead. For example, CocoRosie released an album on both CD and LP, with the LP edition providing a link where you could download their songs in MP3 - acknowledgment of people's love for analog sound as well as their love of digital portability.

    As an aside, someone told me once that something in vinyl provides a natural high-frequency compression, as opposed to digital formats that have to crunch the data down so you're ears don't bleed. The issue though (at least, for him) is that digital compression, being artificial, doesn't relay sound the same, so the CD still has a slightly audible harshness to it, where an LP is a "softer" listen due to its naturally-occurring compress. He claimed that after listening to CDs for hours (especially with headphones) would gradually hurt his ears, whereas he could listen to LPs all night long. I don't know if there's any credence to this, but it would make sense.

    Now, if you really want to talk about extinct, try tapes.

    You're right, of course - but I see more of a> around all the time. I was thinking longer-term.

    As for the natural compression, I've heard that before too. Not sure if it's true, but it seems plausible.

    Now, if you really want to talk about extinct, try tapes.

    When the Tower Records by my old place was going out of business, they were selling tapes for $0.25. It was great. Picked up a bunch of cool stuff.

    I still haven't listened to them though. Don't have a tape player.

    I have a bunch of tapes and can often find good used tapes for 50 cents.
    But when I had to get a new car stereo I was told that unless I wanted to spend major dollars I had to choose between a cd player and a tape player and I went for the former. (I was hoping for a dual player.)

    Good article, Evan.

    Very nice article Evan. It's all about the sine waves. Another name for the digitization phenomenon you are talking about is "aliasing" -- a curious phenomenon in which high frequencies (high tones which are almost inaudible to human ears) can become low frequencies (which are spurious, audible, and very annoying). There is a pretty good article on that here. This article includes tasty tidbits such as the "Nysquist Frequency" for those ready to geek out. For what is is worth, this phenomenon isn't limited to music. It occurs in digital photography (moire effects), and even in the debate about global warming and detection of climate change above background "noise", and sonar for finding submarines, and in oil exploration -- really anything that uses digital data. OK, end of lecture. You got it.
