File format for professional transfer and exchange of digital audio data

IEC 62942:2019 specifies a file format for interchanging audio data between compliant equipment. It is primarily intended for audio applications in professional recording, production, post-production, and archiving. It is derived from the AES31-2 [2] but is also compatible with variant specifications including EBU Tech 3285 [3] to [10], ITU-R BR.1352-3-2007 [11] to [14], and the Japan Post Production Association's BWF-J [15]. This document contains the specification of the broadcast audio extension chunk and its use with PCM-coded audio data. Basic information on the RIFF format and how it can be extended to other types of audio data is given in Annex E. Details of the PCM WAVE format are also given in Annex A. An optional extended format, BWF-E, supports 64-bit addressing to permit file sizes greater than 4 GB.

Dateiformat für die professionelle Übertragung und den Austausch digitaler Audiodaten

Format de fichier pour le transfert et l'échange professionnels de données audionumériques

L'IEC 62942:2019 spécifie un format de fichier qui permet d'échanger des données audio entre des équipements conformes. Il vise principalement les applications audio en ce qui concerne l'enregistrement, la production, la postproduction et l'archivage professionnels. Il est obtenu à partir de l'AES31-2, mais est également compatible avec des spécifications proches, notamment l'EBU Tech 3285, l'ITU-R BR.1352-3-2007, et le BWF-J de la Japan Post Production Association. Le présent document contient la spécification du fragment d'extension audio pour diffusion et de son utilisation avec des données audio codées MIC. Des informations de base sur le format RIFF et sur la façon dont il peut être étendu à d'autres types de données audio sont données à l'Annexe E. Des détails sur le format WAVE MIC sont également donnés à l'Annexe A. Un format étendu facultatif, BWF-E, prend en charge l'adressage 64 bits pour permettre l'utilisation de fichiers dont la taille est supérieure à 4 Go.
