On MacOSForge, Apple has announced that they are releasing the Apple Lossless Audio Codec as an open source project:
The Apple Lossless Audio Codec (ALAC) is a lossless audio codec developed by Apple and deployed on all of its platforms and devices for some years now. Apple is making the Apple Lossless Audio Codec (ALAC) available as an open source project. Full details can be found on the Apple Lossless Audio Codec project page.
The Apple Lossless Audio Codec is a similar to other "lossless" codecs such as FLAC which offer audio compression without any loss in audio information. ALAC is said to compress files only by "about half" as compared to the originals.
Formats such as MP3 and AAC are considered "lossy" and result in much greater compression but at the cost of some fidelity. The main advantage of using ALAC over competing lossless formats is that ALAC is supported by all of Apple's iPods and iOS devices. The format had already been reverse engineered prior to this release, but this opens the door to even more products supporting both ALAC creation and playback.

In the mid-to-late 2000s, Facebook was all about staying connected with friends and family. However, as the social media platform added new features and grew over time, that core experience began to get drowned out.
That changes starting now, according to Meta, which today introduced a new feature that will "bring back the joy" of classic Facebook.
Specifically, Meta has redesigned the...

Update 7:25 pm: Based on comments from our forums, it appears the original Weibo post may have been mistranslated and "8K" actually refers to the high price of the device rather than 8K video recording capabilities. The iPhone 16 Pro currently starts at 7,999 yuan in China.
Our original article follows below.
Apple's forthcoming iPhone 17 Pro models are capable of shooting 8K video, up...

Last week, we covered a report claiming that Apple's book-style foldable iPhone (or "iPhone Fold," as we are provisionally calling it here) will use liquid metal hinges to improve durability and help minimize screen creasing. Today, a Chinese leaker provided more details on the properties of this hinge material that help to clarify why Apple chose it for its first foldable device.
According...
The iOS 19 mockup images that leaker Jon Prosser shared today are not representative of the actual iOS 19 design, Bloomberg's Mark Gurman said on social media.
According to Gurman, the images that are "floating around" are based on "very old builds" or "vague descriptions," and are lacking key features. Gurman says that we can "expect more from Apple in June."
Gurman made the same comment ...

The upcoming iOS 18.4 update for the iPhone adds an Ambient Music feature to Control Center. Below, we take a closer look at how it works.

To use the feature on iOS 18.4, open Control Center and tap on the plus sign in the top-left...
The main advantage of using competing lossless formats is that they are supported by ALL devices on any platform.
They're not. Many devices do not natively support FLAC. iOS devices will natively support ALAC, so that will outnumber "all devices" as you put it.
Can someone explain what "half as much" means? I though the ALAC didn't create fidelity loss. Or is some compression possible without such?
It doesn't create loss in sound. It's a lossless format. What they mean by compression is the file size. So if the original file is 30MB, ALAC compression will make it 15MB in file size but still sound like the original, with no loss of audio.
Android's market share has long surpassed that of iOS. I'd say theres little debate over which open source format will have more success.
Not to start a platform argument, but Android's marketshare may be bigger than the iPhone's. But if you include all iPods (non iOS ones), iPod Touches, and iPads, that market size is certainly still bigger than Android. In terms of devices which support ALAC.
Good news for widespread support, but one wonders why Apple didn't just go with FLAC in the first place.
As with most things Apple, presumably because they thought they could do better. They don't tend to do anything that they don't think is an improvement on something that already exists. If I recall correctly, isn't ALAC about half the file size?
The main advantage of using competing lossless formats is that they are supported by ALL devices on any platform*.
