Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 8 to ISO/IEC 14496-3:2005 was prepared by Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

AMENDMENT 8: MP4FF box for original audio file information
1 Scope
After 1.6.7, add the following subclause:
1.6.8. Definition of the Original Audio File Information for the ISO Base Media file format
1.6.8.1 Introduction
The Original Audio File Information Box permits the storage of the ancillary (non-audio) data of an original
audio file in an ISO Base Media File format file. This file would typically also contain the compressed audio
data of the original audio file. This box is particularly useful in combination with lossless audio coding (e.g.
MPEG-4 ALS, SLS) when restoration of the original input audio file is of interest.
1.6.8.2 Definition
Container: Meta box ('meta')
Mandatory: No
Quantity: Zero or one
The original audio file information provides information about an original audio file, including a file type, and
provides the OriginalHeader(), OriginalTrailer() and AuxData() blocks via the item location box.
The OriginalHeader() block stores the header part of the original audio file and it is referenced from an entry of
the item location box. The header part includes all bytes prior to the first audio data sample in the original file.
The OriginalTrailer() block stores the trailer part of the original audio file and it is referenced from an entry of
the item location box. The trailer part includes all bytes after the last audio data sample in the original file.
The AuxData() block stores additional information added by the encoder related to the original audio file and is
referenced from an e
