Teksty Piosenek writes "Artists and record bosses believe that the best album is the loudest one. Sound levels are being artificially enhanced so that the music punches through when it competes against background noise in pubs or cars. 'Geoff Emerick, engineer on the Beatles' Sgt. Pepper album, said: "A lot of what is released today is basically a scrunched-up mess. Whole layers of sound are missing. It is because record companies don't trust the listener to decide themselves if they want to turn the volume up." Downloading has exacerbated the effect. Songs are compressed once again into digital files before being sold on iTunes and similar sites. The reduction in quality is so marked that EMI has introduced higher-quality digital tracks, albeit at a premium price, in response to consumer demand.'"

The parent poster is completely right, hearing damage is a function of Sound Pressure Level and time, and sound pressure level is a measurement of energy in the air, and not a measure of your perception. Something people don't recognize along these lines, is that a lot of people do terrible damage to themselves by simply driving with the car window down on the freeway, as (in our modern aerodynamic cars) the turbulent airflow can pummel your ears with LF, though it doesn't bother you because it's below 20 Hz. And the wind noise makes you turn up the radio louder.
With regard to graphic EQ, the things were invented, partly, to help engineers correct the acoustic characteristics of rooms -- if your room has a mode at 400 Hz, turn down 400 Hz, if it has some high ringiness due to some resonance, turn down the high end. A 30 band graphic EQ is ideal for this sort of work because some rooms have a bunch of little peaks and troughs on an RTA and you'd need a ton of parametric EQs to do the same goofiness. A 5 band graphic EQ is just for show, you need at least 10 before you can do anything particularly fun, and even then in a car I can't imagine where it'd get you. Maybe you could shape the music over the engine noise or something
It should go without saying, if you want to hear the song the way the band mixed it, they listened to it with a flat EQ, and if you want to enjoy the nuances of a piece of music, don't listen to it in a car. Also, the standard practice in music mixing since forever is to record the song as loud as possible without distorting on the medium. Compression (the audio kind) is a style thing, and bands have been using since the beginning of rock and roll, and particularly with CDs, the music is physically incapable of getting any louder on the medium. You kids have just been cranking up your damn volume knobs.

What's different now that the video shows is the peaks are not getting clipped anymore, instead they reach 0.0 db but the entire mix is digitally volume maximized so almost every single peak is that loud. Vocals and instruments like guitars are always the same maximum loudness. If the singer sings louder or plays harder the volume the listener hears doesn't change.
It's also why the theme song to Casino Royale, You Know My Name by Chris Cornell sounds so weak. Not only is it rock with orchestral backing, so it's already a wall of sound, but since everything is maximized, when Chris starts singing his lungs out there's no change in the volume. The power and energy of his voice and the music is just destroyed. [alterpersanium.com]

Re:A good video explanation (Score:5, Informative)
No, they are getting clipped. Have a closer look for flat topped peaks.
The damage is being done by look ahead limiters like Waves L2, which are the last process in the mastering chain.
These limiters work on psychoacoustic principles, employing some of the temporal masking ideas used in lossy audio compression to make the artifacts of very fast peak limiting as inaudible as possible.
It's known that humans cannot hear short periods of clipping distortion (less than 2ms or so), so these limiters allow that to happen, clamp down a millisecond later, and increase the subjective loudness of the signal without losing 'punch'. As this kind of limiter incorporates a delay line in the audio output path, but not the side chain, it's always looking a few milliseconds ahead and so knows how to react to a peak in advance.
The problem is that if you push a limiter of this kind really hard, it cannot keep it's artifacts inaudible, the clipped periods get longer, and the music starts to sound harsh and tiring.
It's a shame as they a beautifully clean limiters if used correctly, you can knock 4-6db of pop material without the kind of artifacts a traditional analog limiter would produce.

I'd be amazed if any album other than classical music were made without compression. A drum kit or other similar drums without at least some compression sound pretty silly. Basically, you end up burying the entire mix in the mud to keep the drums from clipping... unless you record on analog tape and just let it clip (soft saturation), but in that case, you're really compressing the signal, just without calling it compression. The peak of the sound is just too soft compared to the meat of the sound to give you a usable volume without either adding compression or limiting (which is just a special case of compression).

We always called it "peaking", and it's something that everyone who's recorded an album in the spare bedroom of their band mate's house can attest to - if you record with fewer peaks (places where the sound wave maxes out at the top of the available volume area), it sounds better. It just plain sounds better.
But, take songs off that CD and slam them onto a mix-tape style rotation or an iPod, and you'll be reaching to turn up the volume every time your song comes on.
From what I can tell, recording engineers are responding to the bands who don't want people to have to turn the music up (in particular record execs). It's one of those terrible problems - if everyone would agree on such-and-such date to back off the recording volume and get less peaks (say, no more than 7 per album), everyone's music would instantly sound better. But the fact that everyone's competing, and you don't want your copycat pop punk band to be the quiet one, means it's a self perpetuating problem.

Re:Peaking (Score:5, Informative)
Compression is a necessary part of recording. Judicious use of compression can make a mix really come together and fit everything into it's right place. Notice that I said judicious. It's unfortunately a very useful tool which can easily be abused. OVER compression starts to result in the degradation of the signal. Sometimes you can hear it "pumping and breathing." Over compression is nasty, plus it destroys dynamics. Forget that crescendo on the second movement. Your violin solo is now exactly as loud as your entire orchestra. Are you excited yet? It's also extremely tiring to listen to. Take a pure square wave and pump it through a speaker. Look at that speaker and notice how fast and constantly the speaker cone is vibrating. Take your newfangled over compressed rock/pop CD and extract audio into some sort of multitracking software like Pro Tools or Ardour even. Expand the view a bit and look at the wave form. Looks a lot like a square wave the way the tops and bottoms of that wave form are chopped off doesn't it? Extract audio from a cd you really like from say, the mid 60s. Look at the wave form. There are peaks and valleys and quiet parts and loud parts, the tops and bottoms of the waveform are not chopped off. Now imagine what that new over compressed pop/rock record is doing to your eardrum even at low volume while keeping in mind the speaker cone. Your ear works a lot like that speaker cone. It's vibrating exactly as fast as that speaker cone. It's a mechanical part. There is fatigue involved. Plus it's just boring to listen to. It sucks out emotion and excitement.
By the time you hear your average top 40 hit on the radio, it has been compressed during recording twice (on individual sound sources and probably again when a stereo mix is produced), during mastering, then again at the radio station. Radio stations want their station to catch your ear, plus it helps in keeping signal strength over long distances. Labels want louder songs to compete with the other loud songs, bands want their record to sound like this other loud record, mastering engineers are asked by either the band or the label to make it as loud as possible. You know who's paying the bill so they do it. Recording engineers can be pressured to over-compress by the band or label or just by wanting to have a job in the next year and they might do it as well. Even if they turn in a good balanced mix for mastering, it's a crap shoot whether their mixes will sound the same when the record actually gets put out.
It's a shite state of affairs all around.

It really is true: if you apply too much sound-level compression to a recording, the recording sounds worse. Music is more interesting with some dynamic range. Some of my favorite classic rock songs sound much better from the CD than they do when played on the radio, because the radio station applies sound-level compression.
On the other hand, it's not really wrong for the radio station to apply the sound-level compression; you wouldn't thank them if you set your volume control knob for one song and then the next song was much louder. And the compression helps the music "cut through" the background noise of driving, so you can hear it better. But it is a pity if the CD is mastered with that kind of sound-level compression from the beginning!
Here's another really good web page about this.
http://www.mindspring.com/~mrichter/dynamics/dyna
Just take a look at the Ricky Martin song. The gain was set far too high, and as a result many waveforms went outside legal bounds; when you try to master a CD with a wave that is simply too extreme to be legal, it is hard-clipped to make it legal. That sort of clipping makes an unpleasant sound, and makes the CD sound even louder. And hard-clipping means discarding audio data; there is no way to reconstruct it later.
The above is one of the reasons why vinyl LPs still have their fans. You simply cannot push an LP so hard that it's playing hard-clipped square waves. But a well-mastered CD will have more dynamic range than even the best-mastered LP, and less distortion. (Some of the distortion you get with an LP can actually improve your music, and that's another of the reasons why LPs still have fans. But you could apply a digital effect that sounded like LP distortion, if you wanted to.)

That is partially right, but there's more to it... (Score:5, Insightful)
It's a vicious circle and it is caused essentially by one feature: shuffle mode.
Here's how the problem reveals itself:
Band A decides they want to have the "heaviest, loudest album ever made", so they tell the mastering engineer to make their master louder.
Band B is hears Band A's album and wants to be louder (or at least AS LOUD) as Band A. So they tell their mastering engineer to pump up the volume, too.
Assume the same thing happens with Bands C through L.
Now Band M comes along and they've had these other 12 albums playing on iTunes while they're mixing their album. Band M isn't so concerned with being "the loudest", but when the put their ref CD into iTunes and are listening in shuffle mode, their songs get completely drowned out by a factor of 6-12 dB of amplitude difference.
So Band M now asks their mastering engineer to make their master louder so they'll match up with everyone else's.
And Bands N-Z follow suit.
It's a very difficult domino knockdown to break out of, since no one wants to make the album that is super quiet and requires intervention with the volume knob. (Yes, I'm aware of the "Sound Check" feature in iTunes, but that's just a lousy attempt to solve the problem with technology.)
In 2005 I recorded an album for a Hawaiian band. It was gorgeous and I convinced the band to master the album at Universal because I knew the main mastering engineer and was adamant that he was the ONLY guy who could do the record justice. I was also adamant that the album did NOT need (and would avoid) any compression.
We only boosted the overall level of the album by 4 dB and that was purely using a limiter to ensure no overs.
I then sent the first ref CD to the band member who couldn't be present. He was thrilled with the mastering but had just one question: Do they make it louder when the CDs get pressed?
I told him that it was at the level I was recommending and that Mastering was the time to change levels, but that we really wanted it to sound good, not loud. His response? "Oh. But it's so much quieter than every other CD I own."
And he's right. Compared to every CD that has come out in the past 5 years, his album is seriously quiet. Possibly as much as 8 dB quieter than current albums. And maybe we did it TOO quiet. But it matches in amplitude to CDs that came out in 1989, back when some dynamic range was still an OK thing in music. Nowadays we don't like ANY dynamics.
So who is right? And can we go back?
I've been a HUGE advocate of dynamic range and NOT destroying our months of hard work at the last step in the process. But I can only do what my clients want. And I was really hoping we had a chance with DVD-Audio and other surround formats, but the over-compressors are winning out there, now, too. And it's a bigger problem on that format, since you are now forcing people to change levels between movies and surround music, when both are calibrated identically.

You are SOL if the record company has already applied dumb techniques to the CD before you get it. Peak "compressing", where all of the peaks are maxed out is a real distoriton of the original sound. When you add a heavy handed turn up that clips as well, you get Californication as mentioned. As the article also notes, it's difficult to digitize clipped audio. A clipped wave is like a square wave - it has all frequencies and takes lots of bandwith.
