Defining the Scope of Audio Standards
Explore the responsibilities, focus areas, and technical domains covered by AES standards committees, subcommittees, and working groups
SC-00
Subcommittee on Stabilized Documents
SC-02
Subcommittee on Digital Audio
The scope of the SC-02 Subcommittee on Digital Audio includes, transmission and recording of digital audio data for professional recording and broadcasting including any labeling and control data which accompanies the audio data.
SC-02-01
The scope of the SC-02-01 Working Group on Digital Audio Measurements includes measurement methods for equipment used for the recording, reproduction, and transmission of digital audio signals within the scope of SC-02. It includes effects of perceptually based coding algorithms on audio signals within the scope of SC-02. It includes psychophysical and electrical analysis under all operational and listening conditions. It includes ranking of codecs and test methods to determine presence of coders or their proper operation.
SC-02-02
The scope of the SC-02-02 Working Group on Digital Input-Output Interfaces includes synchronisation and the specification of configurations and operating limits for digital interfaces carrying audio, labeling, and control data within the scope of SC-02.
SC-02-08
The scope of the SC-02-08 Working Group on Audio-File Transfer and Exchange includes, within the scope of SC-02, the specification, user implementation, and adoption of technologies for the exchange of audio data files and editing information among systems, by either transfer over a network or by exchange of physical media.
SC-02-12
The scope of the SC-02-12 Working Group on Audio Applications of Networks includes, within the scope of SC-02, the use of various network types for audio and audio-related applications.
SC-03
Subcommittee on the Preservation and Restoration of Audio Recording
The scope of the SC-03 Subcommittee on the Preservation and Restoration of Audio Recording includes test methods, practices, and specifications pertaining to the life expectancy and retrieval of audio information recorded on mechanical, optical and magnetic systems, including their respective media. It includes coordination with other organizations concerned with this scope and with those concerned with preservation and restoration of recorded images. [group closed 2011-11-14 following AESSC LB11093001]
SC-03-06
The scope of the SC-03-06 Working Group on Digital Library and Archive Systems addresses, within the scope of SC-03, the application of digital technologies for media preservation and access. Among the topics covered are strategies for content conversion and migration, content integrity, methods of access and distribution, storage systems and media, formats for preservation and distribution, and metadata and documentation. The working group will take account of the work of other organizations in this and related fields, and will liaise and work in conjunction with them.
SC-03-07
The scope of the SC-03-07 Working Group on Audio Metadata includes, within the scope of SC-03, the co-ordination and support of the metadata activities of other groups within the AESSC and harmonization with other bodies through working-group level liaisons and the preparation of related documents. It does not include preparation of documents covered in the scopes of other AESSC working groups, except where documents are required to provide co-ordination, overview, and structural requirements for carrying metadata across protocols.
SC-03-12
The scope of the SC-03-12 Working Group on Forensic Audio includes methods for the evaluation of audio material for authenticity and for preparation of audio material for clarity when used as evidence for argument or litigation.
SC-04
Subcommittee on Acoustics
SC-04-03
The scope of the SC-04-03 Working Group on Loudspeaker Modeling and Measurement includes the specification, modeling, and measurement of the electromechanical and free-field radiation characteristics of loudspeakers, individually and in arrays, intended for propagation of audio signals within the scope of SC-04.
SC-04-04
The scope of the SC-04-04 Working Group on Microphone Characteristics includes the specification, measurement, and description of the pressure and pressure gradient transduction characteristics in amplitude, time, phase, and spatial domains of microphones intended for the reception of audio signals within the scope of SC-04, individually and in arrays, with and without accessory response-modifying devices, and the interface, environmental, and compatibility characteristics of such microphones.
SC-04-08
The scope of the SC-04-08 Working group on Measurement and Equalization of Sound Systems in Rooms includes the description, specification, measurement, and calibration of electroacoustic sound systems in rooms and the characteristics of sound presented to an audience.
SC-04-09
This effort identifies practices for estimation of annoyance of man-made sounds in the presence of background sounds, for automotive/aircraft, consumer, professional and land use planning applications. It includes intentionally generated sounds such as music and sporting events, and unintentional sound such as transportation system noise. It is to include auditory masking, not only integrated sound pressure. It considers relative disturbance but does not set thresholds for acceptability. It does not consider health impacts of sound.
Standards Supporters
Our standards are strengthened by the organizations that support their development, helping drive accuracy, reliability, and progress across the audio industry.
