The Apple Lossless Audio Codec (ALAC, / ə ˈ l æ k /), also known as Apple Lossless, or Apple Lossless Encoder (ALE), is an audio coding format, and its reference audio codec implementation, developed by Apple Inc. for lossless data compression of digital music.
In a lossless compressed format, however, the music would occupy a smaller file than an uncompressed format and the silence would take up almost no space at all. Lossless compression formats include FLAC, WavPack, Monkey's Audio, ALAC (Apple Lossless). They provide a compression ratio of about 2:1 (i.e. their files take up half the space of PCM).
An audio coding format [1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus.
FLAC is natively supported on IOS 11, including all "iDevices", but only via the Files (Apple) app or iCloud Drive. iTunes does not support FLAC, with Apple only offering native support for their own similar ALAC lossless audio format. Third-party applications are available in the App Store which enable FLAC playback.
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
Higher compression ratios than other widely used (FLAC/ALAC) open-source lossless audio codecs; Streaming support; Supports multichannel audio and high resolutions; Native support in WavPack 5.x for compressing Direct Stream Digital without converting the source file to PCM. Hybrid/lossy mode; Hardware support (provided by Rockbox firmware)
The short-term predictor is similar to FLAC in its operation – it is a quantized LPC predictor with a losslessly coded residual using Golomb Rice Coding or Block Gilbert Moore Coding (BGMC). [ 3 ] [ 4 ] The long term predictor is modeled by 5 long-term weighted residues, each with its own lag (delay).
