BWF (or Broadcast WAVE, BWAVE) is used for broadcast exchange and as an archival format for first-generation (master) audio files. BWF extends the WAV standard with a mandatory metadata chunk and restricts the audio datastream to Linear PCM (LPCM) or MPEG forms. RF64 is a compatible extended form of this format.
