FLAC (; Gratuitous Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the proper name of the free software project producing the FLAC tools, the reference software bundle that includes a codec implementation. Digital sound compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size[4] and decompresses to an identical copy of the original audio data.

FLAC is an open format with royalty-gratuitous licensing and a reference implementation which is gratis software. FLAC has back up for metadata tagging, anthology comprehend art, and fast seeking.

History [edit]

Development was started in 2000 by Josh Coalson.[5] The bit-stream format was frozen when FLAC entered beta phase with the release of version 0.v of the reference implementation on fifteen January 2001. Version 1.0 was released on 20 July 2001.[5]

On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incorporation of FLAC under the Xiph.org banner. Xiph.org is abode to other gratis compression formats such as Vorbis, Theora, Speex and Opus.[5] [6] [7]

Version ane.3.0 was released on 26 May 2013, at which point development was moved to the Xiph.org git repository.[8]

Composition [edit]

The FLAC project consists of:

  • The stream formats
  • A simple container format for the stream, likewise chosen FLAC (or Native FLAC)
  • libFLAC, a library of reference encoders and decoders, and a metadata interface
  • libFLAC++, an object-oriented wrapper around libFLAC
  • flac, a command-line plan based on libFLAC to encode and decode FLAC streams
  • metaflac, a command-line metadata editor for .flac files and for applying ReplayGain
  • Input plugins for diverse music players (Winamp, XMMS, foobar2000, musikCube, and many more)
  • With Xiph.org incorporation, the Ogg container format, suitable for streaming (also called Ogg FLAC)

The specification of the stream format tin can be implemented by anyone without prior permission (Xiph.org reserves the right to set the FLAC specification and certify compliance), and neither the FLAC format nor any of the implemented encoding or decoding methods are covered past whatsoever patent. The reference implementation is free software. The source lawmaking for libFLAC and libFLAC++ is available nether the BSD license, and the sources for flac, metaflac, and the plugins are available under the GNU General Public License.

In its stated goals, the FLAC project encourages its developers not to implement copy prevention features (DRM) or lossy compression of whatever kind.[9]

Pattern [edit]

File construction [edit]

A FLAC file consists of the magic number FLaC, metadata, and encoded audio. [10]

The encoded sound is divided into frames, which consists of a header, a data block, and a CRC16 checksum. Each frame is encoded independent of each other. A frame header begins with a sync discussion, used to identify the beginning of a valid frame. The rest of the header contains the number of samples, position of the frame, channel assignment, and optionally the sample rate and scrap depth. The data block contains the audio information.[ten]

Metadata in FLAC precedes the sound. Properties like the sample rate and the number of channels are always contained in the metadata. It may also contain other information, the album encompass for example.[10] FLAC uses Vorbis comments for some types of metadata, similar the title and artist name.

Encoding and decoding [edit]

The FLAC encoding algorithm consists of multiple stages. In the first stage, the input audio is divide into blocks. If the audio contains multiple channels, each aqueduct is encoded separately as a subblock. The encoder then tries to find a proficient mathematical approximation of the cake, either by plumbing equipment a simple polynomial, or through full general linear predictive coding. A clarification of the approximation, which is only a few bytes in length, is then written. Finally, the difference between the approximation and the input, called residual, is encoded using Rice coding. In many cases, a description of the approximation and the encoded residual takes upwards less space than using pulse lawmaking modulation.[10]

The decoding process is the reverse of encoding. The compressed residual is offset decoded.[11] [12] The description of the mathematical approximation is then used to summate a waveform. The result is formed by calculation the residual and the calculated waveform.[13] [fourteen] As FLAC compresses losslessly, the decoded waveform is identical to the waveform earlier encoding.

For two-aqueduct stereo, the encoder may choose to joint encode the audio. The channels are transformed into a side aqueduct, which is the difference betwixt the two input channels, and a mid channel, the sum of the two input channels. In place of a mid channel, the left channel or the right aqueduct may exist encoded instead, which is sometimes more infinite efficient.[15]

Even though the reference encoder uses a single block size for the whole stream,[10] FLAC allows the block size in samples to vary per block.

Pinch [edit]

The amount of compression is adamant by various parameters, including the order of the linear prediction model and the block size. Regardless of the amount of compression, the original data tin can always be reconstructed perfectly.

For user's convenience, the reference implementation defines nine compression levels, which are presets of the more than technical parameters to the encoding algorithm. The levels are labeled from 0 to 8, with higher numbers resulting in a higher compression ratio, at the toll of pinch speed. The significant of each compression level varies by implementation.[xvi] [17]

FLAC is optimized for decoding speed at the expense of encoding speed. A benchmark has shown that, while there is little variation in decoding speed as pinch level increases, across the default pinch level five, the encoding process takes up considerably more than time with lilliputian space saved compared to level v.[18]

Comparison to other formats [edit]

FLAC is specifically designed for efficient packing of sound data, unlike full general-purpose lossless algorithms such every bit DEFLATE, which are used in Zero and gzip. While ZIP may reduce the size of a CD-quality audio file by 10–twenty%, FLAC is able to reduce the size of audio information past 40–50% by taking advantage of the characteristics of audio.

The technical strengths of FLAC compared to other lossless formats lie in its ability to be streamed and decoded quickly, independent of compression level.

Since FLAC is a lossless scheme, it is suitable as an annal format for owners of CDs and other media who wish to preserve their audio collections. If the original media are lost, damaged, or worn out, a FLAC copy of the audio tracks ensures that an exact duplicate of the original data can be recovered at whatsoever time. An verbal restoration from a lossy copy (e.one thousand., MP3) of the same data is impossible. FLAC being lossless means it is highly suitable for transcoding due east.one thousand. to MP3, without the normally associated transcoding quality loss betwixt one lossy format and some other. A CUE file can optionally be created when ripping a CD. If a CD is read and ripped perfectly to FLAC files, the CUE file allows after burning of an sound CD that is identical in audio information to the original CD, including track gild and pregap, but excluding CD-Text and other additional information such as lyrics and CD+G graphics.[xix]

Adoption and implementations [edit]

The reference implementation of FLAC is implemented as the libFLAC core encoder & decoder library, with the main distributable program flac being the reference implementation of the libFLAC API. This codec API is besides available in C++ as libFLAC++. The reference implementation of FLAC compiles on many platforms, including most Unix (such as Solaris, BSD) and Unix-like (including Linux), Microsoft Windows, BeOS, and OS/2 operating systems. In that location are build-systems for autoconf/automake, MSVC, Watcom C, and Xcode. In that location is currently no multicore back up in libFLAC, but utilities such as GNU parallel and diverse graphical frontends tin be used to spin up multiple instances of the encoder.

FLAC playback support in portable audio devices and defended sound systems is limited compared to formats such equally MP3[20] or uncompressed PCM. FLAC support is included past default in Windows 10, Android, BlackBerry ten and Jolla devices.

In 2014, several aftermarket mobile electronics companies introduced multimedia solutions that include support for FLAC. These include the NEX series from Pioneer Electronics and the VX404 and NX404 from Clarion.

The European Broadcasting Matrimony (EBU) has adopted the FLAC format for the distribution of high quality audio over its Euroradio network.[21] The Windows operating organisation has supported native FLAC integration since the introduction of Windows 10.[22] The Android operating organization has supported native FLAC playback since version 3.1.[23] [24] macOS High Sierra and iOS xi add native FLAC playback support.[25]

Amidst others the Pono music role player and streaming service used the FLAC format.[26] [27] Bandcamp insists on a lossless format for uploading, and has FLAC as a download selection.[28] The Wikimedia Foundation sponsored a gratuitous and open-source online ECMAScript FLAC tool for browsers supporting the required HTML5 features.[29]
