Shipping Container City

There's an entire city of made out of recycled shipping containers which recently sprang up about two hours outside of Mexico City. Along with a few residential apartments, the eco-friendly Container City houses restaurants, bars, shops, art galleries, and an open public area with ping pong tables. I want to live there! (Note: There’s also a Container City in London. As far as I can tell, they’re similar, but unrelated.) More images after the jump.

Solar P-Flip by Dexim

Dexim has launched five new accessories for use with iPod, iPhone and the BlackBerry at CES 2010. One of the more intelligent offers are solar P-Flip. It can be flipped vertically or horizontally for hands-free viewing and can extend talk time up to eight hours.

Unique design of P-flip allows it easy to fold, carry and charge and it provides efficient charging capabilities using green solar power. It owns a 2000mAh lithium polymer battery that provides for eight hours of talk time, 15 hours for video or games, or 60 hours of music. Holders of this desktop also allows you to charge and sync and can be used as a back-up battery for games and video.

Solar P-Flip is expected to be released in a few months and should retail for USD79.90.

The Loudness Wars: Why Music Sounds Worse

Christopher Clark graphed the peak levels of and RMS levels of three hit songs a year over the past three decades. This image links to a PDF of his full poster, "A Visual History Of Loudness."

As we come to the end of the decade, we turn to one of the more dramatic changes we've heard in music over those 10 years: It seems to have gotten louder.

We're talking about compression here, the dynamic compression that's used a lot in popular music. There's actually another kind of compression going on today — one that allows us to carry hundreds of songs in our iPods. More on that in a minute.

But first, host Robert Siegel talked to Bob Ludwig, a record mastering engineer. For more than 40 years, he's been the final ear in the audio chain for albums running from Jimi Hendrix to Radiohead, from Tony Bennett to Kronos Quartet.

Bob pointed to a YouTube video titled The Loudness War. The video uses Paul McCartney's 1989 song "Figure of Eight" as an example, comparing its original recording with what a modern engineer might do with it.

"It really no longer sounds like a snare drum with a very sharp attack," Ludwig says. "It sounds more like somebody padding on a piece of leather or something like that," Ludwig says. He's referring to the practice of using compressors to squash the music, making the quiet parts louder and the loud parts a little quieter, so it jumps out of your radio or iPod.

Ludwig says the "Loudness War" came to a head last year with the release of Metallica's album Death Magnetic.

"It came out simultaneously to the fans as [a version on] Guitar Hero and the final CD," Ludwig says. "And the Guitar Hero doesn't have all the digital domain compression that the CD had. So the fans were able to hear what it could have been before this compression."

According to Ludwig, 10,000 or more fans signed an online petition to get the band to remix the record.

"That record is so loud that there is an outfit in Europe called ITU [International Telecommunication Union] that now has standardization measurements for long-term loudness," he says. "And that Metallica record is one of the loudest records ever produced."

Old News

"The 'Loudness Wars' have gone back to the days of 45s," Ludwig says. "When I first got into the business and was doing a lot of vinyl disc cutting, one producer after another just wanted to have his 45 sound louder than the next guy's so that when the program director at the Top 40 radio station was going through his stack of 45s to decide which two or three he was going to add that week, that the record would kind of jump out to the program director, aurally at least."

That's still a motivation for some producers. If their record jumps out of your iPod compared with the song that preceded it, then they've accomplished their goal.

Bob Ludwig thinks that's an unfortunate development.

"People talk about downloads hurting record sales," Ludwig says. "I and some other people would submit that another thing that is hurting record sales these days is the fact that they are so compressed that the ear just gets tired of it. When you're through listening to a whole album of this highly compressed music, your ear is fatigued. You may have enjoyed the music but you don't really feel like going back and listening to it again."

Ludwig's final assessment of the decade in music?

"It's been really rough, folks," he says. "But it can get better and I think it will get better. I'm glad it's going to be over."

Digital Compression

Digital compression is the process that allows a song to go from being a very big sound file in its natural state to a very small file in your iPod — so you can carry your entire record library in your pocket. But at what cost?

Dr. Andrew Oxenham is a professor in the psychology department at the University of Minnesota. His specialty is auditory perception — how our brains and ears interact. He also started out as a recording engineer.

Robert Siegel asked him to explain digital compression.

"Really, the challenge is to maintain the quality of a CD, but to stuff it into a much smaller space," Oxenham says. "Let's think about how digital recording works. You start out with a very smooth sound wave and we're trying to store that in digital form. So we're really trying to reproduce a smooth curve [with] these square blocks, which are the digital numbers [the 1s and 0s that are used to encode sound digitally].

"Now, the only way you can make square blocks look like a smooth curve is by using very, very small blocks so it ends up looking as if it's smooth. Now using lots and lots of blocks means lots of storage, so we end up using [fewer] bigger blocks. Which means we end up not representing that curve very smoothly at all."

Lost? Go back and re-read it — you'll get it.

"The difference between the smooth curve and the rough edges you end up with in the digital recording, you can think of as noise because that is perceived as noise," Oxenham says. "It's perceived as an error, something that wasn't there in the original recording. The trick is to take the noise — which is the loss of fidelity — and just make it so you can't hear it anymore."

In Hiding

It's called "masking." Think of it this way: You're having a conversation in a quiet room, and you can hear every word, every mouth noise, every stomach rumble. But if you were having that same conversation outside on a busy street, you'd get the gist of what was said, but you'd probably miss a few words. The traffic noise would mask them.

So let's say you're listening to a Brahms symphony.

"[The loud parts of the music are] giving the coding system a lot of leeway to code things not quite as accurately as it would have to," Oxenham says, "because the ear is being stimulated so much by the loud sound it won't pick up very small variations produced by the coding errors."

In other words, the loud parts of a recording are used to "mask," or hide that noise produced by the rough-edged squares of those digital 1s and 0s.

But are we missing something?

"There are really different levels of MP3 coding," Oxenham says. "You can go from much less data — which people can hear the difference — to higher levels of coding which take up more space on your MP3 player but sound better and are basically indistinguishable from a CD. And I would argue that under proper listening conditions — if it's really indistinguishable from the CD as far as your ear is concerned — then you really haven't lost anything perceptually."

Oxenham likes the convenience of portable MP3 players. But ultimately, he says, he prefers going to concerts.
