Apple's lossless audio format goes open source

Apple made its lossless audio format open source this week, allowing for others to view and change the code for use in their own software and tools.

As Daring Fireball notes, the format--which goes by the name, Apple Lossless Audio Codec (or ALAC)--adopted the Apache license yesterday.

ALAC was first introduced to Apple's Mac OS X Core Audio framework in 2004, where most users saw it as part of iTunes 4.5. It let users rip a CD into smaller compressed files without reduction in quality. Still, the resulting files are considerably larger than the more ubiquitous MP3, … Read more

A 'cure' for the Loudness Wars: Give us two mixes!

Most of today's music on CD, LP, or download is compressed to sound loud all the time. The engineers, producers, and record labels are afraid not to make music sound as loud as possible.

Dynamic range compression isn't new, it's been used by recording, mixing, and mastering engineers for decades. A little bit of compression is fine, but the unnatural onslaught of dynamically compressed sound obliterates musical nuance, delicacy, and emotional power. Compression's loud-all-the-time nature sucks the life out of music. The overuse of compression has become known as the Loudness War.

The CD isn't dead yet

Reports of the death of the CD have been greatly exaggerated. With sales hovering around 326 million units in the U.S. in 2010, the CD still generates a sizable hunk of income for the music business. You may not give a hoot about that, but if you care about sound quality, it still makes sense to buy a great-sounding CD player. I buy one or two CDs a week on average, and as I recently pointed out, it may be a very long time before iTunes or Amazon ever get around to selling CD-quality downloads. Why waste your money … Read more

Poll: Would you pay more for high-resolution music on iTunes?

Last month the Internet was ablaze with articles like Mark Milian's "Apple in talks to improve sound quality of music downloads." Milian did mention that the improved sound might be accompanied by higher prices, but no further details were covered.

He also said, "Many models of Mac computers can play 24-bit sound, and the iTunes program is capable of handling such files. But most portable electronics, and many computers, don't support 24-bit audio." Right, so I can't see why significant numbers of iTunes buyers would even consider purchasing higher-resolution files.

Does lossless audio guarantee good sound?

It took a long time for me to work up any enthusiasm for the original digital consumer format, the CD. Coming from an all-analog perspective, first-generation CDs and CD players in the early 1980s didn't light my fire. The problem wasn't that they sounded "bad," it was that CDs robbed music of its soul and emotional connections. LPs' sound engaged you; the CD's sound was too easy to ignore. People put music on, and started reading, talking, working, anything but actually listening to music.

That's why I waited six years to buy my first … Read more

Five ways to make digital music sing

Neil Young says the tech industry doesn't care as much about music quality as it should.

Perhaps that's because the average iPod-toting iTunes customer doesn't give a second thought to whether the digital file of the latest single they just bought is uncompressed or lossless.

Young told a bunch of tech luminaries gathered for an industry conference as much on Wednesday: "People's understanding has been skewed by MP3s and convenience. It's important to get music out there...but not at the expense of quality."

He's not the only one who feels that … Read more

The '500,000-song' iPod isn't surprising

IBM researchers have reportedly demonstrated technology that will increase hard drive capacity 100-fold, as well as offer major improvements in energy consumption (leading to much longer battery life) and better reliability. Production is estimated in seven to ten years.

The reports summarizing the researchers' findings, which were published in Science (subscription required), use the shorthand "500,000 songs on a portable MP3 player" to describe the advance.

Today's iPod lineup contains no product advertised to hold 5,000 songs, so I'm not sure where the 500,000 figure came from. In fact, the current highest-capacity iPod is 160GB, … Read more
