La sp\u00e9cification associ\u00e9e au format a \u00e9t\u00e9 publi\u00e9e sous l'identifiant RFC 9639.

Avec l'apparition du RFC, toutes les informations sont rassembl\u00e9es dans un seul document, \u00e9liminant ainsi le besoin pour les d\u00e9veloppeurs de consulter le code source de la biblioth\u00e8que de r\u00e9f\u00e9rence ou de parcourir des archives de listes de diffusion \u00e0 la recherche de d\u00e9tails.        <\/p>\n<p>Le codec FLAC utilise des m\u00e9thodes de compression sans perte qui garantissent la pr\u00e9servation compl\u00e8te de la qualit\u00e9 originale du flux audio et son identit\u00e9 par rapport \u00e0 la version de r\u00e9f\u00e9rence. Les m\u00e9thodes de compression sans perte utilis\u00e9es permettent de r\u00e9duire la taille du flux audio d'origine de 50 \u00e0 60 %. FLAC est un format de flux enti\u00e8rement libre, impliquant non seulement l'ouverture des biblioth\u00e8ques impl\u00e9mentant des fonctions d'encodage et de d\u00e9codage, mais aussi l'absence de restrictions quant \u00e0 son utilisation et \u00e0 la cr\u00e9ation de variantes d\u00e9riv\u00e9es.
