Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Amendment 5 to ISO/IEC 23003-2:2010 was prepared by Joint Technical Committee ISO/IEC JTC 1,

Part 2:
Spatial Audio Object Coding (SAOC)
AMENDMENT 5: SAOC Reference Software
Page 1, Clause 11
Replace Clause 11 with the following.
11 Reference software
11.1 Reference software structure
11.1.1 General
This clause contains simulation software for SAOC as defined in Clause 1 to Clause 9 and Annex A to
Annex G. This software has been derived from verification models used in the process of developing the
standard.
Reference software is normative in the sense that it correctly implements the SAOC transcoding/decoding
processes described in this document. Complying implementations indicated in this document are not
expected to follow the algorithms or the programming techniques used by the reference software.
Although the decoding software is considered normative, it cannot add anything to the textual technical
description of SAOC included in this document.
The software contained in this clause and in Annex H is divided into three categories.
a) Bitstream decoding software is catalogued in 11.2. This software accepts bitstreams encoded
according to the normative specification given in this document and decodes the streams into the
audio signals associated with each bitstream. While this software appears in the normative part
of this specification, attention is drawn to the fact that the implementation techniques used in this
software are not considered normative (several different implementations could produce the same
result) but the software is considered normative in that it correctly implements the SAOC decoding
processes described in this document.
b) Bitstream encoding software is catalogued in Annex H. This software creates bitstreams from
associated audio signals. The encoders are provided as a means to obtain bitstreams with the
normative syntax described in this document. The techniques used for encoding are not specified
by this document, and the quality and complexity of these encoders has not been optimized.
c) Utility software is catalogued in Annex H. This software was found useful by the
...
