How to edit an MP3 audio file

Whether it's a two-hour Grateful Dead concert or a 45-minute DJ mix, we all have an MP3 in our music collection that gets skipped for being too long. Tragically, there's usually one or two great songs in these recordings that would otherwise be in heavy rotation if they weren't tied to such a tediously long file.

Well, today we're going to show you how to cut these songs loose by opening up and editing your MP3s in Audacity. The whole process is relatively painless, and if you set it up correctly, you can easily drag and … Read more

China Unicom: 5,000 iPhones sold in first weekend

The iPhone didn't get quite the reception in China as it did in other markets.

The exclusive carrier for the device in the country, China Unicom, said Tuesday that it signed up 5,000 iPhone subscribers in the first four days it was available. While that's certainly not a blockbuster opening weekend, the carrier says it's pleased nonetheless.

"We are satisified with iPhone sales so far, and we aim to have an additional 1 million new 3G subscribers each month in the near future," China Unicom Chairman Chang Xiaobing told Reuters.

How to set up an iPod Nano

In recent statements, Apple reports 50 percent of new iPod sales are going to customers who are buying their very first iPod. That means millions of people are setting up an iPod for the first time. Personally, I'm a little scared for them.

The iPod celebrates its 8th birthday this month, and it has come a long way. What started out purely as a digital music player has evolved into a video-recording, movie-renting, fitness-tracking, do-everything device. For first-time users, I can imagine the experience of setting up a new iPod is as overwhelming as it is exciting.

MLB uses World Series to warm up Android app

Alex Rodriguez won't be the only big baseball name making its World Series debut Wednesday night.

When the New York Yankees and Philadelphia Phillies take the field for the first game of the World Series, Major League Baseball will also introduce its popular At Bat mobile application for Android phones.

Previously only available for Apple's iPhone and iPod Touch, the application can be downloaded from MLB.com's mobile site but not the Android Marketplace, since the league is still testing the app in advance of next season. For that reason, the Android version will be free.

At Bat for Android delivers live scoreboards, box scores, and pitch-by-pitch or play-by-play updates, along with updated video highlight reels. The big difference between the free beta Android version the full paid version now for iPhone is that there's no option for live streaming video. There will, however, be live streaming audio for the remainder of the baseball postseason.

MLB says for now it's testing the waters, and it doesn't mean there will definitely be an Android app for next season.

"We were intrigued by the adoption of Android and the recent announcements by carriers releasing devices in the coming weeks and months, and we wanted to take this opportunity during World Series" to test it out, said Adam Ritter, vice president of wireless at MLB Advanced Media. "The beta Android app will give us the feedback we need from a product and technical perspective to see what's possible for next season."

It's been a big day for Android, Google's free Linux-based mobile operating system, and MLB's embrace of the OS shows its technology savvy. While iPhone and iPod Touch sales have exploded, Android is also gaining momentum, as seen with Wednesday's high-profile launch of the Motorola Droid series. There are at least 10 Android phones available now or within the next week, and at least 10 more rumored models on the way for the holidays or next year.

MLB At Bat 2009 and MLB At Bat Lite (the free version) is currently on 1.2 million devices, according to MLB.

How to record audio with your computer

There's an entire hardware industry built of products that ease the pain of recording audio to a basic home computer. But the truth is, you really don't need things like USB turntables, USB cassette decks, or USB microphones in order to make decent digital audio recordings.

A willingness to experiment and $15 PC microphone or $3 minijack cable should be enough to get you up and running with computer audio recording. The trouble is, most people just don't know where to begin. I can't promise that he following How To video and slideshow will turn your … Read more

Quanta takes stake in gesture control maker

While Panasonic, Sony, and other heavy hitters in the consumer electronics world are working hard to bring 3D to TVs, a far less recognizable name is working to bring 3D to computer interfaces.

You might never have heard of Canesta--and that's OK--but the largest contract manufacturer of notebook PCs, Quanta Computer, has. On Wednesday, Canesta will announce that it's raised another $16 million in funding, from new investors Quanta, chipmaker SMSC, and returning backers Carlyle Growth Partners, Hotung Venture Group, and Venrock. The new round of capital brings Canesta's total raised since 2001 to $70 million.

Kohjinsha's doublewide laptop display

CHIBA, Japan--This otherwise run-of-the-mill laptop from local PC purveyor Kohjinsha has not one, but two widescreen displays.

One of the 10.1-inch screens actually slides behind the other, so it's able to be closed like a normal laptop. When they slideout they form an admittedly odd-looking, but useful dual display setup.

Also inside the laptop: a 1.6 Ghz AMD Athlon Neo-MV40, 4GB of memory, Bluetooth, a TV tuner, and a biometric fingerprint reader. The OS will be Windows 7 Home Premium, graphics are DirectX 10 compatible, and the whole thing weighs about 4 pounds. More photos of the sliding screens in action after the jump.… Read more

A Netbook/ultramobile hybrid from Sharp

CHIBA, Japan--The Sharp NetWalker comes off like a computer with an identity crisis.

It's part Asus Eee PC Netbook and part Samsung Q1 ultramobile PC.

And it's a little bit puzzling.

The NetWalker is dressed up like a super-petite Netbook, weighing less than a pound, with a five-inch touchscreen and a measly 512MB of memory and wireless LAN.

It's got a pretty robust battery life--up to 10 hours, according to Sharp--and runs Ubuntu. There's a Firefox browser, Thunderbird for e-mail, a Twitter app, and some open-source programs for word processing and reviewing spreadsheets, so you can … Read more
