La specifica associata al formato \u00e8 stata pubblicata con l'identificativo RFC 9639. Il RFC ha ottenuto lo stato di \u00abStandard Proposto\u00bb e descrive lo stato attuale del formato di compressione FLAC, ad eccezione dell'aggiunta esplicita del supporto per l'audio a 32 bit e dell'introduzione di limitazioni per la sua adattabilit\u00e0.    <\/p>\n<p>Si prevede che la pubblicazione dell'RFC semplifichi la creazione ex novo di nuove implementazioni del decoder FLAC e consenta di ripristinare il supporto per il formato per accedere ai file audio conservati in un lontano futuro, dopo che il formato FLAC e le sue implementazioni saranno cadute nell'oblio. In precedenza, agli sviluppatori era fornita documentazione dal progetto Xiph e un'implementazione di riferimento contenente tutti i dettagli necessari. Con la comparsa dell'RFC, tutte le informazioni sono state raccolte in un unico documento, sollevando gli sviluppatori dalla necessit\u00e0 di consultare il codice sorgente della libreria di riferimento o di scorrere gli archivi delle mailing list alla ricerca di dettagli.        <\/p>\n<p>Il codec FLAC utilizza metodi di codifica lossless, il che garantisce la completa conservazione della qualit\u00e0 originale del flusso audio e la sua identit\u00e0 rispetto alla versione di riferimento. I metodi di compressione lossless consentono di ridurre la dimensione del flusso audio originale del 50-60%. FLAC \u00e8 un formato di flusso completamente libero, che implica non solo l'apertura delle librerie con le funzioni di codifica e decodifica, ma anche l'assenza di restrizioni sull'uso e sulla creazione di varianti derivate.
