There's has been a War going on in music over the past 30 years. And I don't mean the one between mainstream and indie music, West side and East side rappers, or the never-ending feud between Megadeth and Metallica. This war is over your stereo.
Go into your music library right now and play a song, any song made in the past 10 years. Adjust your volume setting so that it is comfortable for you. OK, now that you've done that, go and play a song recorded in the 60's. Play some Doors or maybe the Beatles (how about that new remastered box set if you're lucky enough to get it?). But don't touch your volume knob! I know you want to right now.
Want to know how I knew that? You probably lowered the volume when you played the first song because it's so loud. Now that you're playing something at a normal sound level, you cannot hear it. Yes, that's right, I said “normal.”
When you see a live band at a bar or small venue, it sounds natural. The kick drum thumps the room, the bass shakes the floor, and the guitars floating high above them both. Everything has it's place in the musical spectrum. When you listen to a recording done the right way, this natural sound is what you get.
However, when you listen to a recording done the new way, everything is as loud as it could possibly be. The thumping kick drum has nowhere to go, the bass is flat and plain, and the guitars sound boring. There is no dynamic range anymore (dynamic range: the ratio between the loudest and softest sound your ears can hear), there is just one setting: loud. And it cannot go any louder, digital recording won't allow it.
So lets say you've got a recording of 2 guitars, a bass guitar and drums. The 2 guitars and bass are maxing out the available amplitude (the correct term for “loudness”), now throw some drums into the mix. It didn't get louder though because you already maxed it out. So what happens? When a drum is hit, it sucks out the other instruments. Listen carefully to the first song you listened to. When a drum hits, suddenly you cannot hear the other instruments as well for that second. This is called pumping or breathing, the instruments go in and out throughout the recording. And it sounds terrible.
This loudness war actually goes back farther than the past 30 years. It first gained momentum back when jukeboxes filled with 7” vinyl singles were the mainstay of every bar/diner/bowling alley/wherever in the United States and abroad. The volume of the jukebox was set by the bar owner and very rarely touched. Recording artists soon realized if they cranked up the amplitude of their recording on the vinyl itself, their song would be louder than the others in the jukebox and therefore be more noticeable. It's the same motivation that continues the loudness war today.
However, this wasn't necessarily a bad thing back then. Vinyl and other analog media are very tolerant of high amplitude, you can go louder than it is “designed for” and it will still sound good. In fact, people intentionally do this on their analog recordings to get a desired effect. This is called “tape saturation” or “tape distortion.” It is distortion, but a “good” kind.
Digital recording does not have that benefit. When you get to peak amplitude, you now have bad harmonics, sour tones and distortion. If it breaks the 0dB barrier (the highest amplitude a digital recording will go), things are simply cut. Here's an example of Rush's song Tom Sawyer, released in 1981.
Now, let's artificially boost the same song by 9dB to approximate the amount of amplitude boosted in modern recordings.
See how the the tops and bottoms of the waveform are completely flat? That right there is called Peaking. And it sounds like shit. Modern recordings are generally like this. Here is the newest single That Was Just Your Life off of Metallica's most recent album, Death Magnetic:
Where's the wave? I can't see it, it's just one giant block of distortion. Needless to say, it sounds terrible. So bad that the mixing engineer refused to put his name on it. This was all the record labels' fault.It's not just rock music that suffers from this. Here is Jay-Z's newest single D.O.A. (Death of Autotune) off of his newest album The Blueprint 3. The title of the song is something I can definitely get behind (though that would take it's own article), but the method makes me cringe:
I suppose you have to tackle one problem with the music industry at a time... There is another problem with the loudness war. Have you ever listened to music for long periods of time? Two or more hours? Did your ears hurt? I bet they did. That is called Ear Fatigue. Listening to recordings that loud physically damages your hearing. And we certainly don't need any more damage to our ears, daily life does that enough!
