Pub. 2013; Addendum 2014-03-24; Revised 2015; Revised 2018
Abstract:
High-performance media networks support professional quality audio (16 bit, 44,1 kHz and higher) with low latencies (less than 10 milliseconds) compatible with live sound reinforcement. The level of network performance required to meet these requirements is available on local-area networks and is achievable on enterprise-scale networks. A number of networked audio systems have been developed to support high-performance media networking but until now there were no recommendations for operating these systems in an interoperable manner. This standard provides comprehensive interoperability recommendations in the areas of synchronization, media clock identification, network transport, encoding and streaming, session description and connection management.

Abstract:
This standard is intended to apply to three- and five-pin circular connectors, commonly and generically known as miniature XLR-type, used for the balanced interconnection of all categories of sound system components for professional audio, commercial, recording, broadcast, and similar applications, regardless of function, type, or level of the signal. It specifies the application and polarity of analog signals for these connectors and is intended to avoid the inversion of absolute polarity among the items in the analog signal chain.

Abstract:
An increasing number of surround sound microphones are becoming available, however, there has been no common standard for the connectors between microphone and recording device. It is expected that a standard connection will create a basis for smaller and lighter recording devices.
This standard specifies a connector type and contact assignment for microphones having up to six balanced analog output channels, as used in surround sound applications. It includes specifications for marking and identification for the audio channels. It includes recommendations for cable type and detailed wiring. It is expected that other applications will also use this connection.

Abstract:
This standard for networked command, control, and connection management for integrated media is an IP-based peer-to-peer network protocol, in which any device on the network may initiate or accept control, monitoring, and connection management commands. The AES64 protocol has been developed around three important concepts: structuring, joining, and indexing. Every parameter is part of a structure, and control is possible at any of the levels of the structure, allowing for control over sets of parameters. Parameters can be joined into groups, thereby enabling control over many disparate parameters from a single control source. Every parameter has an index associated with it and, once discovered, this index provides a low bandwidth alternative to parameter control.

Abstract:
This document describes a standard contact assignment and gender convention for users of the 25-contact D-type connector as a multi-channel balanced audio interconnection, in analogue or AES3 digital form, to facilitate interconnection of equipment from different suppliers using standardized cables. The intent is to simplify the rapid and reliable interconnection of equipment in temporary installations, perhaps using rented equipment, although the method may be extended to permanent installations where appropriate.

Abstract:
Commonly used modular connectors are widely used, but are fragile in demanding installations, where a broken connection can affect the application critically. This is not important in many applications, such as structured data cabling for use with computer networks, or simple interconnect cabling and patching using Category 5 (or better) data cable. However, in professional audio applications, a broken connection can affect the application critically. A standard ruggedized fitting will promote system security in these applications. This document specifies a ruggedized data connector that is compatible with 8-position 8-contact (8P8C) modular connectors, commonly (though inaccurately) called RJ-45 connectors, with regard to mechanical aspects for proper mating and locking.

Pub. 2012; Reaffirmed 2017; Reaffirmed 2022
Abstract:
AES41 provides for the carriage of audio metadata by embedding it in the audio samples themselves. This tightly associates the meta-data with the audio, yet makes it fragile so that changes to the audio will invalidate the meta-data. Several metadata sets have been defined, covering applications such as cascaded compression (bit rate reduction), and loudness control. This part describes the format for the data to be transmitted with audio to signal loudness and true peak metadata as used in EBU Technical Recommendation R128. A method of carrying this data is described in Part 1 of this Standard.

Several metadata sets have been defined, covering applications such as cascaded compression (bit rate reduction), and loudness control. This part describes the format for the data to be transmitted with audio decoded from MPEG-1 Layer II or MPEG-2 LSF Layer II encoding. The data may be used to aid a subsequent re-encoding process. A method of carrying this data is described in Part 1 of this Standard.This standard revises AES41-2009: AES standard for digital audio - Recoding data set for audio bit-rate reduction
