Comitetul IETF (Internet Engineering Task Force), care se ocup\u0103 cu dezvoltarea protocoalelor \u0219i arhitecturii internetului, a finalizat formarea RFC pentru codec-ul audio liber FLAC (Free Lossless Audio Codec), dezvoltat de comunitatea Xiph.Org. Specifica\u021bia asociat\u0103 cu formatul a fost publicat\u0103 sub identificatorul RFC 9639. RFC a primit statutul de \u201eStandard propus\u201d \u0219i descrie starea actual\u0103 a formatului de comprimare FLAC, cu excep\u021bia ad\u0103ug\u0103rii explicite a suportului pentru sunet de 32 de bi\u021bi \u0219i a introducerii de restric\u021bii pentru adaptarea acestuia. <\/p>\n

Se presupune c\u0103 publica\u021bia RFC va simplifica crearea de la zero a unor noi implement\u0103ri ale decoder-ului FLAC \u0219i va permite recrearea suportului pentru format pentru a accesa fi\u0219ierele audio p\u0103strate \u00een viitorul \u00eendep\u0103rtat, dup\u0103 ce formatul FLAC \u0219i implement\u0103rile sale vor fi uitate. \u00cen trecut, dezvoltatorii aveau la dispozi\u021bie documenta\u021bia de la proiectul Xiph \u0219i o implementare de referin\u021b\u0103 care con\u021binea toate detaliile necesare. Odat\u0103 cu apari\u021bia RFC, toat\u0103 informa\u021bia a fost concentrat\u0103 \u00eentr-un singur document, eliber\u00e2nd dezvoltatorii de necesitatea de a consulta codul surs\u0103 al bibliotecii de referin\u021b\u0103 sau de a r\u0103sfoi arhivele listelor de discu\u021bii \u00een c\u0103utarea detaliilor. <\/p>\n

Codec-ul FLAC utilizeaz\u0103 metode de codare f\u0103r\u0103 pierderi (lossless), ceea ce garanteaz\u0103 p\u0103strarea complet\u0103 a calit\u0103\u021bii originale a fluxului audio \u0219i identitatea acestuia cu varianta de referin\u021b\u0103. Metodele de compresie f\u0103r\u0103 pierderi utilizate permit reducerea dimensiunii fluxului audio ini\u021bial cu 50-60%. FLAC este un format de streaming complet liber, care presupune nu doar deschiderea bibliotecilor cu implement\u0103rile func\u021biilor de codificare \u0219i decodificare, ci \u0219i absen\u021ba restric\u021biilor la utilizare \u0219i crearea de variante derivate. Codul bibliotecilor de referin\u021b\u0103 este distribuit sub licen\u021ba BSD.
