Specification of interactions between an audio and a systems subsystem

Editions

Edition - 1: Second Edition

Publication Year: 0
Status: released
Motivations: MPEG audio can have complex interactions with Systems, e.g. File Format.
Objectives: Show what interactions can occur and demonstrate how they should be handled.

Edition - 2: ISO/IEC TR 14496-24 Audio and systems interaction, 2nd edition

Publication Year: 0
Status: ongoing
Motivations:
Objectives: ISO/IEC TR 14496-24:2008 describes the desired joint behavior of MPEG-4 Systems (MPEG-4 File Format) and MPEG-4 Audio codecs. It is desired that MPEG-4 Audio encoders and decoders permit finite length signals to be encoded to a file (particularly MPEG-4 files) and decoded again to obtain the identical signal, subject to codec distortions. This will allow the use of audio in systems implementations (particularly MPEG-4 Systems), perhaps with other media such as video, in a deterministic fashion. Most importantly, the decoded signal will have nothing “extra” at the beginning or “missing” at the end.
