broadcast wave format (D-Cinema) (BWF)

Broadcast Wave Format (BWF) is an audio file format based on the WAV file format for cross- platform data exchange of audio files.

The BWF file format was specified and standardized by the European Broadcasting Union( EBU) in 1996, and subsequently adopted by the Audio Engineering Society( AES). It is used in broadcasting and supports data exchange between audio servers with different file formats.

In terms of structure, the BWF file format consists of the PCM encoded audio data and metadata containing the information about the file format, sampling rate, recording date, performer and other information. A BWF file can have a size of up to 4 gigabytes and can be processed by programs that interpret the Waveform Audio File (WAV). Also, a WAV file can be converted to a BWF file by adding the metadata.
