| An object-oriented schema for describing time-varying
3-D audio scenes is proposed. The creation of
this schema was motivated by the fact that current
virtual reality description schemes (VRLM,X3D) have
only basic 3-D audio description capabilities In contrast,
MPEG-4 AudioBIFs has advanced 3-D audio
features but is not designed as a metadata language.
MPEG-4 BIFs is particularly targeted as a binary
scene description language for scene rendering purposes
only. Our proposed 3-D audio scene description
schema features state of the art 3-D audio description
capabilities while being usable both as a
metadata scheme for describing 3-D audio content
(for example, 5.1 or Ambisonics B-format) and as a
format for scene rendering. |
