AES41-1-2012-r2022: AES standard for digital audio - Audio-embedded metadata - Part 1: General
Printing Date:
2017-12-31
Publication History:
Pub. 2000; Reaffirmed 2005; Revised 2009; Revised 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 metadata with the audio, yet makes it fragile so that changes to the audio will invalidate the metadata. Several metadata sets have been defined, covering applications such as cascaded compression (bit-rate reduction), and loudness control. This Part specifies the method by which a metadata set is embedded in the audio samples. Other parts define the content and format of the metadata sets. This standard revises AES41-2009: AES standard for digital audio - Recoding data set for audio bit-rate reduction

AES32-tu: PROPOSED DRAFT AES standard for professional audio interconnections Fibre optic connectors, cables, and characteristics (for Trial Use)
Printing Date:
2000-07-12
Publication History:
Pub. 2000 for Trial Use
Abstract:
This document covers fibre-optic connectors and cables for professional use in audio applications not included in other AES standards.
AESSC wishes to provide opportunity for discussion and trial use before the document is presented as a call for comment leading to finalization of the standard. It is therefore initiating a process of public discussion via the Internet. (25 pages)

AES31-3-2021: AES standard for network and file transfer of audio - Audio-file transfer and exchange - Part 3: Simple project interchange
Printing Date:
2021-05-19
Publication History:
Pub. 1999; Revised 2008; Reaffirmed 2013; Reaffirmed 2019 with editorial corrections; Revised 2020; Revised 2021
Abstract:
This standard provides a convention for expressing edit data in text form for digital audio stored as random access disk files in a manner that enables simple and accurate computer parsing while retaining human readability. It also describes a method for expressing sample-accurate time-code information in character notation, and simple automation for stereo & surround panning and audio gain. (49 pages)

AES31-1-2001 (s2012): AES standard for network and file transfer of audio - Audio-file transfer and exchange Part 1: Disk format
Printing Date:
2011-10-17
Publication History:
Pub. 2001; Reaffirmed 2006, reaffirmed 2011; Stabilized 2012.
Abstract:
This document defines a disk format specification to maintain compatibility with as wide a user base as possible to facilitate audio-file transfer and exchange between differing systems. The document does not describe a complete disk format but provides enough information to choose a proprietary system that will maintain compatibility. The main objective of this disk format specification is to ensure compatibility with as wide a user base as possible to facilitate audio-file transfer and exchange between differing systems.

AES28-1997 (s2012): AES standard for audio preservation and restoration - Method for estimating life expectancy of compact discs (CD-ROM), based on effects of temperature and relative humidity (includes Amendment 1-2001)
Printing Date:
2009-02-16
Publication History:
Pub. 1997; Am. 1 - 2001; Reaffirmed 2003; Reaffirmed 2008; Stabilized 2012.
Abstract:
This standard specifies test methods for estimating the storage life expectancy (LE) of information stored on compact discs (CD-ROM). Only the effects of temperature and relative humidity are considered. Block error rate (BLER) is the measured response and the end-of-life criterion. An Eyring model is developed from accelerated test results. Data are normalized to 25 degC and 50 % relative humidity, and the LE, percent compliance, and confidence intervals at these conditions are calculated. (22 pages)

AES27-1996 (s2012): AES recommended practice for forensic purposes -- Managing recorded audio materials intended for examination
Printing Date:
2008-02-05
Publication History:
Pub. 1996; reaffirmed 2002, reaffirmed 2007; Stabilized 2012.
Abstract:
This document specifies recommended practices for safekeeping, conveyance, inspection, description, and labeling of audio recordings offered as evidence in criminal investigations, in criminal or civil proceedings, or in other forensic applications. It does not cover analysis of magnetic tapes or other recording media for the purposes of authenticity determination, talker identification, copyright violation, enhancement of oral conversations or other signals, or otherwise characterizing signals recorded on such tapes.
