Broadcast Wave Format (BWF) is an extension of the popular Microsoft WAV audio format and is the recording format of most file-based non-linear digital recorders used for motion picture, radio and television production.
It is based on the Microsoft RIFF/WAVE format and Wave Format Extensible for multichannel parameters. Additions are made to the basic specification to allow for more than 4 GB file sizes when needed (the new maximum filesize is now approximately 16 exabytes). The format is transparent to the BWF and all its supplements and chunks. RF64 WAV ...
The WAV file is an instance of a Resource Interchange File Format (RIFF) defined by IBM and Microsoft. [3] The RIFF format acts as a wrapper for various audio coding formats. Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed audio in the linear pulse-code modulation (LPCM) format.
BWF (Broadcast Wave Format) is a standard audio format created by the European Broadcasting Union as a successor to WAV. Among other enhancements, BWF allows more robust metadata to be stored in the file. See European Broadcasting Union: Specification of the Broadcast Wave Format (EBU Technical document 3285, July 1997). This is the primary ...
Part 1 - Disk format Ensures the ability to read files across platforms. Part 2 - File format Specifies use of monaural Broadcast Wave Format files Part 3 - Project interchange Provides a method of exchanging edit data in a text format. This allows an audio edit in one DAW to be opened in another, with little or no difference in the mix.
Resource Interchange File Format (RIFF) is a generic file container format for storing data in tagged chunks. [2] It is primarily used for audio and video, though it can be used for arbitrary data. [3] The Microsoft implementation is mostly known through container formats like AVI, ANI and WAV, which use RIFF as their basis. [4]
There are several competing approaches to including a time code in AVI files, which affects usability of the format in film and television post-production, although it is widely used. [15] For WAV audio files, Broadcast Wave (BWF) extensions were designed to standardize post-production metadata, but an equivalent for AVI files has not emerged ...
An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content —in computer science it is often limited to the audio file format , but its wider use usually refers to the physical method used to store the data.
