Komitet IETF (Internet Engineering Task Force), kt\u00f3ry zajmuje si\u0119 rozwojem protoko\u0142\u00f3w i architektury internetu, zako\u0144czy\u0142 formu\u0142owanie RFC dla wolnego kodeka d\u017awi\u0119kowego FLAC (Free Lossless Audio Codec), opracowanego przez spo\u0142eczno\u015b\u0107 Xiph.Org. Powi\u0105zana ze formatem specyfikacja zosta\u0142a opublikowana pod identyfikatorem RFC 9639. RFC uzyska\u0142 status \u201eProponowanego standardu\u201d i opisuje istniej\u0105cy stan formatu kompresji FLAC, z wyj\u0105tkiem wyra\u017anego dodania wsparcia dla 32-bitowego d\u017awi\u0119ku oraz wprowadzenia ogranicze\u0144 dla jego adaptacji. <\/p>\n

Przewiduje si\u0119, \u017ce publikacja RFC upro\u015bci tworzenie nowych realizacji dekoder\u00f3w FLAC od podstaw i umo\u017cliwi przywr\u00f3cenie wsparcia dla formatu, aby uzyska\u0107 dost\u0119p do zachowanych plik\u00f3w d\u017awi\u0119kowych w dalekiej przysz\u0142o\u015bci, po tym jak format FLAC oraz jego realizacje zostan\u0105 zapomniane. Wcze\u015bniej deweloperzy otrzymywali dokumentacj\u0119 od projektu Xiph oraz referencyjn\u0105 realizacj\u0119, zawieraj\u0105c\u0105 wszystkie niezb\u0119dne szczeg\u00f3\u0142y. Dzi\u0119ki pojawieniu si\u0119 RFC wszystkie informacje zosta\u0142y zebrane w jeden dokument, eliminuj\u0105c potrzeb\u0119 odniesienia si\u0119 do \u017ar\u00f3d\u0142owego kodu referencyjnej biblioteki lub przeszukiwania archiw\u00f3w list mailingowych w poszukiwaniu szczeg\u00f3\u0142\u00f3w. <\/p>\n

Kodek FLAC stosuje metody kodowania bezstratnego (lossless), co gwarantuje pe\u0142ne zachowanie pierwotnej jako\u015bci strumienia d\u017awi\u0119kowego oraz jego to\u017csamo\u015b\u0107 z wersj\u0105 referencyjn\u0105. Stosowane metody kompresji bezstratnej pozwalaj\u0105 na zmniejszenie rozmiaru pierwotnego strumienia d\u017awi\u0119kowego o 50-60%. FLAC jest ca\u0142kowicie wolnym formatem strumieniowym, kt\u00f3ry oznacza nie tylko otwarto\u015b\u0107 bibliotek z realizacj\u0105 funkcji kodowania i dekodowania, ale tak\u017ce brak ogranicze\u0144 dotycz\u0105cych u\u017cywania i tworzenia wersji pochodnych. Kod referencyjnych bibliotek jest dystrybuowany na licencji BSD.
