Digital audio compressed by FLAC's algorithm can typically be reduced to 50–60% of its original size〔(【引用サイトリンク】title=Comparison )〕 and decompress to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. FLAC has support for metadata tagging, album cover art, and fast seeking. FLAC support in portable audio devices and dedicated audio systems is somewhat limited compared to uncompressed PCM or common lossy formats such as MP3, but FLAC is generally supported by more hardware devices than competing lossless compressed formats that may have intellectual property constraints. == History == Development was started in 2000 by Josh Coalson.〔(【引用サイトリンク】title=News )〕 The bit-stream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. Version 1.0 was released on 20 July 2001.〔 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 behind other free compression formats such as Vorbis, Theora, Speex and Opus.〔 Version 1.3.0 was released on 26 May 2013, at which point development was moved to the Xiph.org git repository. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「FLAC」の詳細全文を読む スポンサード リンク
