AES Convention 116 · Paper 6058 · May 2004

Abstract

Since the early days of audio stereophony we tend to think of audio transmission and audio presentation in terms of loudspeaker feeds or "channels". This seemed to be appropriate for as few channels as two and still reasonable for five, but is rapidly loosing its meaning with the advent of technologies like e.g. wave field synthesis.
A key part of MPEG-4 is the introduction of object-oriented thinking for the description, generation, transport, and rendering of audio scenes. Binary Information for Scenes (BIFS) is that part of the MPEG-4 standard that enables to transmit scene descriptions together with the audio signals to facilitate the final rendering.
The latest version of AudioBIFS (Version 3) now has a number of improvements and new concepts that are explained in detail.
