Description: 

This standard defines a formal model of describing how audio data is structured. It does not specify carrying audio data. The model supports combinations of channel, object and scene-based formats of audio data. It can be used with a large variety of audio file formats – such as BWF and RF64 – to provide a complete set of technical and informative metadata that describes the audio content of the file. At first sight this may seem trivial but what it does is to completely unlock file formats to as-yet-unknown audio arrangements and applications. These could, for example, encompass channel-based audio (where numbers such as 1, 2, 5.1, 7.1, 10.1, 22.2 and 15.1 might occur to you), or scene-based, periphonic, binaural or even object-based audio. Tech 3364 can cope with all of these and it will accommodate as-yet-unknown formats by extension of the ADM. It effectively makes the audio file format substantially agnostic to its payload.
