ALAC stands for Apple Lossless Audio Codec and it is a high-definition lossless audio format made by Apple, Inc. Just as other compression solutions for audio (the likes of FLAC, TTA or APE) or the same way as ZIP, RAR and 7z do not alter the original data, ALAC also leaves the source audio data untouched.
What’s so good about ALAC?
First and foremost, it is the default high-definition audio codec for all Apple devices, meaning that is has outstanding support out-of-the-box.
Is it popular?
Absolutely! From the hardware devices (like the iPod) right down to the operating systems (OSX / macOS / iOS / tvOS / watchOS), it is possible to play this format on any Apple device. From this standpoint it is really important for any third-party player to seamlessly integrate with with this ecosystem.
