Well, not really, but I thought it would make a good, nerdy Audiophile/Highlander reference...

I figure the death of the mp3 is only a few years off anyway. With broadband download speeds increasing and storage capacity following Moore's Law, we already have 160GB iPods which could hold my entire CD collection at full quality, no compression.
I want to make my next release available for download at 44.1/16 and I plan to not master it at full throttle, hopefully people interested in my music will appreciate that, I think there's going to be a sea change in the way music is being mixed and compressed... I hope.

The Death of High Fidelity

Appeared on Rolling Stone issue 1042/1043 (Dec. 27, 2007 - Jan. 10, 2008), the following is an article I agree with completely…however, it dosen’t alleviate the 50+ lbs of vinyl I had to haul around to gigs.

The Death of High Fidelity
In the age of MP3s, sound quality is worse than ever
By Robert Levine

David Bendeth, a producer who works with rock bands like Hawthorne Heights and Paramore, knows that the albums he makes are often played through tiny computer speakers by fans who are busy surfing the Internet. So he’s not surprised when record labels ask the mastering engineers who work on his CDs to crank up the sound levels so high that even the soft parts sound loud.

Over the past decade and a half, a revolution in recording technology has changed the way albums are produced, mixed and mastered -almost always for the worse. “They make it loud to get [listeners’] attention,” Bendeth says. Engineers do that by applying dynamic range compression, which reduces the difference between the loudest and softest sounds in a song. Like many of his peers, Bendeth believes that relying too much on this effect can obscure sonic detail, rob music of its emotional power and leave listeners with what engineers call ear fatigue.

“I think most everything is mastered a little too loud,” Bendeth says. “The industry decided that it’s a volume contest.” Producers and engineers call this “the loudness war,” and it has changed the way almost every new pop and rock album sounds. But volume isn’t the only issue. Computer programs like Pro Tools, which let audio engineers manipulate sound the way a word processor edits text, make musicians sound unnaturally perfect. And today’s listeners consume an increasing amount of music on MP3, which eliminates much of the data from the original CD file and can leave music sounding tinny or hollow. “With all the technical innovation, music sounds worse,” says Steely Dan’s Donald Fagen, who has made what are considered some of the best-sounding records of all time. “God is in the details. But there are no details anymore.”

The idea that engineers make albums louder might seem strange: Isn’t volume controlled by that knob on the stereo? Yes, but every setting on that dial delivers a range of loudness, from a hushed vocal to a kick drum - and pushing sounds toward the top of that range makes music seem louder. It’s the same technique used to make television commercials stand out from shows. And it does grab listeners’ attention - but at a price. Last year, Bob Dylan told ROLLING STONE that modern albums “have sound all over them. There’s no definition of nothing, no vocal, no nothing, just like - static.” In 2004, Jeff Buckley’s mom, Mary Guibert, listened to the original 3/4″ tape of her son’s recordings as she was preparing the tenth-anniversary reissue of Grace. “We were hearing instruments you’ve never heard on that album, like finger cymbals and the sound of viola strings being plucked,” she remembers. “It blew me away because it was exactly what he heard in the studio.”

To Guibert’s disappointment, the remastered 2004 version failed to capture these details. So last year, when Guibert assembled the best-of collection So Real: Songs From Jeff Buckley, she insisted on an independent A&R consultant to oversee the reissue process and a mastering engineer who would reproduce the sound Buckley made in the studio. “You can hear the distinct instruments and the sound of the room,” she says of the new release. “Compression smudges things together.” Too much compression can be heard as musical clutter; on the Arctic Monkeys’ debut, the band never seems to pause to catch its breath. By maintaining constant intensity, the album flattens out the emotional peaks that usually stand out in a song. “You lose the power of the chorus, because it’s not louder than the verses,” Bendeth says. “You lose emotion.” The inner ear automatically compresses blasts of high volume to protect itself, so we associate compression with loudness, says Daniel Levitin, a professor of music and neuroscience at McGill University and author of ‘This Is Your Brain on Music: ‘The Science of a Human Obsession. Human brains have evolved to pay particular attention to loud nQises, so compressed sounds initially seem more exciting. But the effect doesn’t last. “The excitement in music comes from variation in rhythm, timbre, pitch and loudness,” Levitin says. “If you hold one of those constant, it can seem monotonous.” After a few minutes, research shows, constant loudness grows fatiguing to the brain. Though few listeners realize this consciously, many feel an urge to skip to another song. “If you limit range, it’s just an assault on the body,” says Tom Coyne, a mastering engineer who has worked with Mary J. Blige and Nas. “When you’re fifteen, it’s the greatest thing - you’re being hammered. But do you want that on a whole album?”
To an average listener, a wide dynamic range creates a sense of spaciousness and makes it easier to pick out individual instruments - as you can hear on recent albums such as Dylan’s Modern Times and Norah Jones’ Not Too Late. “When people have the courage and the vision to do a record that way, it sets them apart,” says Joe Boyd, who produced albums by Richard Thompson and R.E.M.’s Fables of the Reconstruction. “It sounds warm, it sounds three-dimensional, it sounds different. Analog sound to me is more emotionally affecting.”

Rock and Pop producers have always used compression to balance the sounds of different instruments and to make music sound more exciting, and radio stations apply compression for technical reasons. In the days of vinyl records, there was a physical limit to how high the bass levels could go before the needle skipped a groove. CDs can handle higher levels of loudness, although they, too, have a limit that engineers call “digital zero dB,” above which sounds begin to distort. Pop albums rarely got close to the zero-dB mark until the mid- 1990’s, when digital compressors and limiters, which cut off the peaks of sound waves, made it easier to manipulate loudness levels. Intensely compressed albums like Oasis’ 1995 (What’s the Story) Morning Glory? set a new bar for loudness; the songs were well-suited for bars, cars and other noisy environments. “In the Seventies and Eighties, you were expected to pay attention,” says Matt Serletic, the former chief executive of Virgin Records USA, who also produced albums by Matchbox Twenty and Collective Soul. “Modern music should be able to get your attention.” Adds Rob Cavallo, who produced Green Day’s American Idiot and My Chemical Romance’s The Black Parade, “It’s a style that started post-grunge, to get that intensity. The idea was to slam someone’s face against the wall. You can set your CD to stun.” It’s not just new music that’s too loud. Many remastered recordings suffer the same problem as engineers apply compression to bring them into line with modern tastes. The new Led Zeppelin collection, Mothership, is louder than the band’s original albums, and Bendeth, who mixed Elvis Presley’s 30 #1 Hits, says that the album was mastered too loud for his taste. “A lot of audiophiles hate that record,” he says, “but people can play it in the car and it’s competitive with the new Foo Fighters record.”
Just as CDs supplanted vinyl and cassettes, MP3 and other digital music formats are quickly replacing CDs as the most popular way to listen to music. That means more convenience but worse sound. To create an MP3, a computer samples the music on a CD and compresses it into a smaller file by excluding the musical information that the human ear is less likely to notice.

Much of the information left out is at the very high and low ends, which is why some MP3s sound flat. Cavallo says that MP3s don’t reproduce reverb well, and the lack of high-end detail makes them sound brittle. Without enough low end, he says, “you don’t get the punch anymore. It decreases the punch of the kick drum and how the speaker gets pushed when the guitarist plays a power chord.” But not all digital music files are created equal. Levitin says that most people find MP3s ripped at a rate above 224 kbps virtually indistinguishable from CDs. (iTunes sells music as either 128 or 256 kbps AAC files -AAC is slightly superior to MP3 at an equivalent bit rate. Amazon sells MP3s at 256 kbps.) Still, “it’s like going to the Louvre and instead of the Mona Lisa there’s a 10 megapixel image of it,” he says. “I always want to listen to music the way the artists wanted me to hear it. I wouldn’t look at a Kandinsky painting with sunglasses on.” Producers also now alter the way they mix albums to compensate for the limitations of MP3 sound. “You have to be aware of how people will hear music, and pretty much everyone is listening to MP3,” says producer Butch Vig, a member of Garbage and the producer of Nirvana’s Nevermind. “Some of the effects get lost. So you sometimes have to over-exaggerate things.”
Other producers believe that intensely compressed CDs make for better MP3s, since the loudness of the music will compensate for the flatness of the digital format. As technological shifts have changed the way sounds are recorded, they have encouraged an artificial perfection in music itself. Analog tape has been replaced in most studios by Pro Tools, making edits that once required splicing tape together easily done with the click of a mouse. Programs like Auto-Tune can make weak singers sound pitch-perfect, and Beat Detective does the same thing for wobbly drummers. “You can make anyone sound professional,” says Mitchell Froom, a producer who’s worked with Elvis Costello and Los Lobos, among others. “But the problem is that you have something that’s professional, but it’s not distinctive. I was talking to a session drummer, and I said, ‘When’s the last time you could tell who the drummer is?’ You can tell Keith Moon or John Bonham, but now they all sound the same.”

So is music doomed to keep sounding worse? Awareness of the problem is growing. The South by Southwest music festival recently featured a panel titled “Why Does Today’s Music Sound Like Shit?” In August, a group of producers and engineers founded an organization called Turn Me Up!, which proposes to put stickers on CDs that meet high sonic standards. But even most CD listeners have lost interest in high-end stereos as surround-sound home theater systems have become more popular, and superior-quality disc formats like DVD-Audio and SACD flopped. Bendeth and other producers worry that young listeners have grown so used to dynamically compressed music and the thin sound of MP3s that the battle has already been lost. “CDs sound better, but no one’s buying them,” he says. “The age of the audiophile is over.”

Get the Most of your iPod.

1. Increase the bit rate: Higher bit rates = better sound. Set your iTunes to rip at 192 kbps, or better - we recommend jacking it all the way to 320. (AustinVegas recommends always 320 for MP3 but you can always rip straight to WMA)
2. Ditch the white earbuds: For an upgrade. try higher-end earphones from Shure. Ultimate Ears or Etymotic. Bonus; fewer muggings! (AV says true that on the muggings!)
3. Don’t re-rip!!! Morality aside, it’s a bad idea to re-rip a CD burned from MP3s - the sound will be noticeably worse. (AV says: Did you ever make a copy of someone elses copy of a cassette tape? Yeah with this is the same concept)
4. Upgrade from MP3: Use iTunes’ AAC format or windows Media Audio . (AV says SKIP! the AAC, it’s proprietary and if you don’t plan on using iPod for life, don’t get stuck with this format, use WMA instead).

    ???

    WMA is _far_ more proprietary than AAC -- WMA is Windows Media Audio, as in "Microsoft." As in one company. What can _possibly_ be more proprietary than one company controlling audio compression standards?

    If you really want to get an idea of "proprietary" or not when it comes to AAC and WMA, do this: try to find the WMA spec -- the whole spec, describing every bit that is part of a WMA file / stream, and how to generate the correct value for that bit. With MPEG, you can go to ansi.org to get info on how to get the specs, which describe _every_ header, _every_ data section, in programmer-friendly pseudocode, for a very reasonable fee, no matter _who_ you are. Try to do that with Microsoft. I know, because i've done both of these things. For $240 (I think), I was able to purchase a download of the 11172 and 13838 MPEG audio specs, described with enough detail that I could write my own encoder, or decode any un-DRMd stream I was given. I've also tried this with Microsoft in 2001, and their response was "we'll consider it for $800,000, and you can only use it for what we say" (they ended up saying "no" to the company I was working for at the time).

    Really -- anyone who thinks that WMA is somehow more open than AAC is _quite_ mistaken.

    i'm going to come up with a new genre of music that consists only of pulse-width modulated squarewaves at -0.0db, such that the entire song is at the theoretical maximum volume for its entirety. then the world will understand!

          What volume control? There aren't silly things called "volume controls". That's why everything has to be so much louder.

          Jeez. So absurd!

              the funny thing is I cant stand mp3 anyway and only put aif on my ipod ...I dont need to store shit loads of music there since thats what my computer and the extensive amount of external drives i have is for. I cant believe that we are settling for sound quality that is lower than that of a cassette tape just for the sake of storage space. I mean it's not that difficult to plug in an digital player and dump some more songs on there when you get tired of the old ones. to me music is not only about the song but the quality of the sound as well.

              I did a little test the other day on my car stereo and even noticed the difference on there between the aiff file and the mp3 ...the mp3 sounded lieke I was listening to a transistor radio( my stereo is pretty crappy in the car) vs the aiff which sounded listenable on my shitty system. And then as a dj I see tons of guys and gals playing mp3 on live sound systems like there is no difference.

              Hopefully the mp3 will die !!

                  This is a virtual can of worms, but to be honest I can tell the difference between converters in a studio, but in a car listening environment I have a difficult time telling the difference between a 320kbps mp3 and a wave file on my iPod (maybe this is more a limitation of iPod's converters?)

                  The difference between a 128kbps mp3 (which looked like the standard for a minute) and a wave are huge. I suppose on large, nice systems the difference tends to stand out.

                  That said I have a coworker who, no lie, has spent over $40,000 on a home stereo. He has bought special power cables (over a $1,000 each) and special coasters for the components to stack with. To him it makes a difference, I have to admit it sounded good, but the brain adjusts after about 30 seconds anyway and it just sounded good... hmmm.

                    I do notice that an aif file sounds better on my ipod than an mp3... when I listen using sony in-ear headpones... but rarely am I using my ipod in an environment where it matters.

                    car? with the road noise and engine running?

                    subway? bus? walking on busy city streets?

                    I think that high quality mp3 (though I do prefer aac) is just fine for most portable applications. when I'm at home is when I want the good sound on the good speakers!
