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.
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 ISO documents 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 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 1: MPEG-H, 3D audio profile and levels
Page 346
Add the following section after Clause 18.
19 MPEG-H 3D Audio Profile Definition
19.1 Profile: Main Profile
The Main Profile for MPEG-H 3D Audio contains all normative bitstream elements and normative
decoder tools defined in MPEG-H 3D Audio specification.
That means that the following tools will be included Main Profile decoders:
— MPEG-H 3D Audio Core Decoder
— HOA Rendering
— SAOC 3D Renderer
— Static object metadata (MAE) and rendering
— Dynamic object metadata (OAM) and rendering
— Generic Loudspeaker Rendering/Format Conversion
— Immersive Loudspeaker Rendering/Format Conversion
— Binaural Rendering Time Domain and/or Frequency Domain
— H2B Binaural Rendering
— Loudness Metadata
— DRC processing
ISO/IEC 23008-3:2015/Amd.1:2016(E)
