FLAC is specifically designed for efficient packing of audio data, unlike general-purpose lossless algorithms such as DEFLATE, which are used in ZIP and gzip. While ZIP may reduce the size of a CD-quality audio file by 10–20%, FLAC is able to reduce the size of audio data by 40–50% by taking advantage of the characteristics of audio.
As such, the user normally doesn't have a raw AAC file, but instead has a .m4a audio file, which is a MPEG-4 Part 14 container containing AAC-encoded audio. The container also contains metadata such as title and other tags, and perhaps an index for fast seeking. [2] A notable exception is MP3 files, which are raw audio coding without a ...

The Windows Mobile operating system is able to support playback of FLAC files through the use of plugins or third-party applications such as TCMP and others. [34] On Windows Phone 7 (WP7) there is no FLAC support available in the default Zune media player [ 35 ] [ 36 ] though playback is supported in third-party applications like a Flac Player ...
According to Apple, audio files compressed with its lossless codec will use up "about half the storage space" that the uncompressed data would require. Testers using a selection of music have found that compressed files are about 40% to 60% the size of the originals depending on the kind of music, which is similar to other lossless formats. [3] [4]
Possible bitrate and latency combinations compared with other audio formats. Opus supports constant and variable bitrate encoding from 6 kbit/s to 510 kbit/s (or up to 256 kbit/s per channel for multi-channel tracks), frame sizes from 2.5 ms to 60 ms, and five sampling rates from 8 kHz (with 4 kHz bandwidth) to 48 kHz (with 20 kHz bandwidth, the human hearing range).
After FLAC compression, the file size is typically reduced to 50-60% of the original size, which is the same as saying that it is reduced by 40-50%. Although previous versions may have been confusing, I think the current text in the article states this accurately without any contradiction. LiberatorG 15:24, 1 August 2016 (UTC)
