Surround Sound Standards

Introduction MPEG Surround (Spatial Audio Coding, SAC) [23003-1] is an International Standard that was finalized by MPEG in January 2007. It is capable of re-creating N channels based on M < N transmitted channels and additional control data. In the preferred modes of operating the Spatial...

This document specifies the general channel assignment and the metadata for multichannel audio format. This document, with its channel mapping and labelling content, provides the unified usage of channel assignments for source devices, digital audio interfaces and sink devices. The general channel...

Master algorithms and standards for transparent coding of high-fidelity audio Here is an in-depth treatment of algorithms and standards for transparent coding of high-fidelity audio. Readers learn how algorithms for high-quality digital audio deliver transparent signal reproduction with a minimum...

This part of ISO 11546 specifies in situ methods for the determination of the Sound insulation performante (insertion loss) of machine enclosures. lt applies to a total enclosure only and not to the individual Panels from which the enclosure is made. NOTES 1 Sound insulation for...

This part of ISO 11546 specifies laboratory methods for the determination of the Sound insulation performante (insertion loss) of small machine enclos-Ures. lt applies to a total enclosure only and not to the individual Panels from which the enclosure is made. NOTES 1 Sound insulation...

Classification and properties of glazing compounds and sealants; design considerations (daylighting, durability, thermal expansion and contraction, thermal insulation, double and multiple glazing, sound insulation, fire protection, recommended glazing thicknesses, safety considerations...

This document describes methods for calculating the attenuation of sound due to line-of-sight blockage or shielding from non-level terrain. This method applies to sound propagating from an airplane to locations on the ground during ground roll, climbout after liftoff, and landing...

ESDU 02009 provides methods for the estimation of averaged radiation efficiencies of orthotropic, rectangular plates which are simply supported at all edges and surrounded by an infinite baffle. Isotropic plates are also included as a special case of orthotropic plates. The method used is...

Specifies the materials, sizes and construction of softwood and hardwood surrounds for use with steel windows and doors specified in BS 990:Part 2:1972.

General Concrete shall be produced and placed in accordance with this Section when it is to be used for minor works or when small quantities of concrete are needed. Mass concrete for applications such as concrete foundations to platform walls, manholes, duct or drain pipe surrounds, and...

This part of IEC 61937 describes the method to convey non-linear PCM bitstreams encoded according to the MPEG-4 AAC format and its extensions spectral band replication, parametric stereo and MPEG surround, framed in MPEG-4 LATM/LOAS.
