AES71-2018: Recommended Practice Loudness Guidelines for Over the Top Television and Online Video Distribution
Printing Date:
2018-07-21
Publication History:
Pub. 2018
Abstract:
This AES Recommended Practice (RP) describes the many issues related to online audio Loudness variations. It provides comprehensive recommendations documenting effective guidelines for managing audio Loudness of soundtracks of television and video content available to consumers by Over-The-Top (OTT) and by Online Video Distributors (OVD).
When followed, these guidelines will provide consistent Loudness, appropriate playback loudness range, reduce audio quality degradation from excessive limiting, preserve the original artistic intent, and improve the listening experience. This document does not provide specific recommendations about target playback loudness or dynamic range.

AES-R16-2021: AES Standards Report - PTP parameters for AES67 and SMPTE ST 2059-2 interoperability
Printing Date:
2021-10-20
Publication History:
Pub: 2016; Rev. 2021
Abstract:
Three profiles for Precision Time Protocol (PTP) might potentially be used in the professional media environment: the Peer-to-Peer Default PTP Profile of IEEE Std 1588-2008, the Media Profile of AES67 and the SMPTE Profile of SMPTE ST 2059-2. This report compares the profiles and identifies features and parameter ranges that should enable interoperability among equipment conforming to the different profiles.

AES31-4-2015: AES standard for network and file transport of audio - Part 4: XML Implementation of Audio Decision Lists
Printing Date:
2016-02-08
Publication History:
Pub. 2015
Abstract:
This document provides a syntax mapping for AES31-3 Edit Decision Markup Language (EDML) to XML Schema Language. This facilitates the expansion of the Audio Decision List format to include non-ASCII characters and updates the format facilitating it\92s implementation using standard XML parsers and tools. It also supports multi-byte chacter sets for human-readable metadata in all territories worldwide. This document includes both an XML schema definition and an XSLT implementation capable of transforming a conforming XML instance document back to EDML. [37 pages]

AES70-3-2018: AES standard for audio applications of networks - Open Control Architecture - Part 3: OCP.1: Protocol for IP Networks
Printing Date:
2019-01-14
Publication History:
Pub: 2015, Rev: 2018
Abstract:
AES70 defines a scalable control-protocol architecture for professional media networks. AES70 addresses device control and monitoring only; it does not define standards for streaming media transport. However, the Open Control Architecture (OCA) is intended to cooperate with various media transport architectures.

AES69-2020: AES standard for file exchange - Spatial acoustic data file format
Printing Date:
2020-12-06
Publication History:
Pub. 2015, Revised 2020
Abstract:
Binaural listening is growing fast, because of growing sales in smartphones, tablets and other individual entertainment systems. The lack of a standard for the exchange of head-related transfer functions (HRTF) means each company keeps its binaural capture and rendering algorithms private. 3D audio is arising, and binaural listening could be the very first 3D audio vector with sufficient fidelity of HRTF.
The use of convolution-based reverberation processors in 3D virtual audio environments has grown with the increase in available computing power. Convolution-based reverberators guarantee an authentic and natural listening experience, but also depend on the acoustic quality of the applied spatial room impulse response (SRIR).
With a standardized file format for HRTF and SRIR data, each company can contribute its best algorithms, providing good personalized capture and/or rendering, allowing the consumer to choose a combination of technologies for the best quality of experience.
This document standardizes a file format to exchange space-related acoustic data, such as binaural listening parameters in the form of head related transfer functions. The format is scalable to match the available rendering process and is designed to include source materials from different databases.
