Which file extension is associated with a WAV file that includes production metadata such as timecode?

• A. WAV
• B. BWAV/BWF
• C. AIFF
• D. MP3

Answer: (B)

In production audio, you need metadata that travels with the audio file to keep everything synchronized and well documented. A standard WAV file carries just the audio samples, with no guaranteed, structured way to store production notes like timecode. The Broadcast Wave Format extends WAV by adding dedicated chunks for metadata, including a time reference and often an iXML section that can hold timecode, description, originator, and other production details. This makes BWAV/BWF the clear choice for a WAV file that includes production metadata such as timecode, because it explicitly signals that the file is carrying broadcast-quality metadata and is intended for professional post workflows. The other formats don’t inherently provide this standardized production metadata format: plain WAV is generic, AIFF is another uncompressed format but not the standard for production metadata in many pipelines, and MP3 is a compressed format not suited for precise timecode and production logging.
