AAF (Advanced Authoring Format)

professional file interchange format used to move a sequence or timeline between different software applications, primarily for audio post-production. Unlike an OMF, an AAF can contain more complex metadata, including volume automation, clip gain, and references to the original high-resolution media, making it the modern standard for sound turnovers. It essentially translates the editor's audio timeline into a language the sound mixer's software (like Pro Tools) can understand.
