AES-X206 Frequency Response Data file format
Initiated on 2012-02-08 by Subcommittee SC-02, and assigned to Working Group
SC-02-01
Scope:
An industry practice has evolved over the past years for the format of a file format for data exchange of frequency response (magnitude and phase) data of transducers and other audio systems. Two variants are documented. The scope of this project is to define the FRD format as closely as possible in standard terms.
AES-X205 Application of connectors, miniature XLR-type polarity and gender
Initiated on 2012-02-08 by Subcommittee SC-05, and assigned to Working Group
SC-05-02
Scope:
This standard shall apply to three-pin and five-pin circular connectors, generically known as miniature XLR-type, used for the connection of balanced audio signals between sound system components for professional audio and similar applications, regardless of function, type, or level of the signal. It specifies the application and polarity of signals for these connectors. This standard does not pertain to the dimensions of the connectors and does not consider safety issues arising from usage.
AES-X196 multi-channel audio in AES3
Initiated on 2011-07-28 by Subcommittee SC-02, and assigned to Working Group
SC-02-02
Scope:
An AES3 interface running at 192kHz could be adapted to carry 8 channels of linear audio sampled at 48kHz. The scope of this project is to formalise the use of the interface in this way, and to specify a means of signalling the use of an AES3 interface in this way to cover various use cases such as asynchronous switching, behaviour of existing devices, equipment not designed for this mode, and so on. Operational guidance may also be developed, if necessary.
AES-X192 streaming audio-over-IP interoperability
Initiated on 2010-12-01 by Subcommittee SC-02, and assigned to Working Group
SC-02-12
Scope:
To specify protocols and interoperability guidelines for professional, low-latency streaming audio over high-performance IP networks.
AES-X193 Array and cluster polar radiation measurements
Initiated on 2010-05-20 by Subcommittee SC-04, and assigned to Working Group
SC-04-01
Scope:
The standard will specify how the angular measurements of polar radiation data for arrays or cluster arrangements of loudspeakers shall be made and documented. This acquired data is suitable for application in room acoustic, electro-acoustic, and sound system predictions, and loudspeaker data sheets.
AES-X189 Connector for surround microphones
Initiated on 2010-05-20 by Subcommittee SC-04, and assigned to Working Group
SC-04-04
Scope:
to establish a standard for the connector type and contact assignment for microphones having four or more balanced analog output channels, as used in surround sound applications. It will include specifications for marking and identification for the audio channels. It will include recommendations for cable type and detailed wiring.
AES-X170 Integrated Control, Monitoring and Connection Management for Digital Audio Networks
Initiated on 2010-04-29 by Subcommittee SC-02, and assigned to Working Group
SC-02-12
Scope:
to create and standardize:
- A set of structured Internet Protocol-based messages that can be used to control single parameters or groups of parameters, and to monitor these parameters. The parameters are associated either with typical signal processing functionality within audio devices, synchronization between such devices, or connections between such devices.
- A mechanism for grouping of device parameters, and messages required to implement such grouping.
- A mechanism for the control of latency within networks of audio devices, and a specification of the messages and parameters required for the control of such latency.
- Parameter modifiers, and the messages required to create and configure such modifiers.
- Security levels, and the messages required to set and get such levels.
AES-X188 Screen-less navigation for high-resolution audio on Blu-ray Discs
Initiated on 2009-08-10 by Subcommittee SC-02, and assigned to Working Group
SC-02-08
Scope:
to recommend a method for authoring an audio-only Blu-ray Disc to enable playback in screen-less consumer systems, and to provide simple stream and track selection using the remote control of a normal Blu-ray Disc player.
AES-X183 Audio application of 25-way D-type connectors
Initiated on 2009-01-10 by Subcommittee SC-05, and assigned to Working Group
SC-05-02
Scope:
to recommended a pin assignment and gender for 25-way D-type connectors used to connect multiple audio signals in balanced analogue or AES3 digital form. Excludes consideration of connector and cable types for specific applications.
AES-X182 AES/Ethernet Simple Open Protocol
Initiated on 2008-08-05 by Subcommittee SC-02, and assigned to Working Group
SC-02-02
Scope:
to specify a means for transmission over category 5 data cable of unidirectional digital audio and bidirectional control data. Intended applications are active loudspeakers and amplifiers for live performance and for installations.
AES-X155 Production recording metadata set (iXML)
Initiated on 2008-05-02 by Subcommittee SC-03, and assigned to Working Group
SC-03-06
Scope:
to specify an XML-based metadata set to communicate file-based and project-based metadata between various stages of audio workflow in production, telecine, editorial, and post production. Production may include recordings made in studios and on location.
AES-X162 Amendment to AES31-2, File-size extension using the "RF64" technique
Initiated on 2007-12-17 by Subcommittee SC-02, and assigned to Working Group
SC-02-08
Scope:
This amendment to AES31-2 provides a method of extending audio files beyond the limits set by the RIFF Wave format. It uses the "RF64" technique to permit 64-bit file addressing to accommodate longer recording times and multiple channels in a single file.
AES-X172 Criteria for the authentication of digital audio recordings using an ENF methodology
Initiated on 2007-11-19 by Subcommittee SC-03, and assigned to Working Group
SC-03-12
Scope:
This report discusses the minimum procedure for the authentication of digital audio recordings intended to be offered as evidence or otherwise utilized in civil, criminal, or other fact-finding proceedings. This authentication is based on the analysis of low-level induced signals at electric-network frequency (ENF).
AES-X180 Amendment 5 to AES3, extensions to status data
Initiated on 2007-10-27 by Subcommittee SC-02, and assigned to Working Group
SC-02-02
Scope:
This amendment adds a flag to indicate hidden data within a PCM signal, provides indications for two additional sampling frequencies, and clarifies the use of certain status bits when the signal is non-PCM.
AES-X160 Powering and Analog Interface for Constant-Current Line Drive Transducers
Initiated on 2007-01-28 by Subcommittee SC-04, and assigned to Working Group
SC-04-04
Scope:
To define the powering parameters for constant current line drive (CCLD) transducers such as microphones, which may also be compliant with IEEE 1451.4.
AES-X161 Digital interface for loudspeakers
Initiated on 2007-01-19 by Subcommittee SC-02, and assigned to Working Group
SC-02-02
Scope:
To identify the different circumstances in which digital loudspeakers are used, arrange them into groups with similar requirements, specify those requirements, and identify existing standards that would be appropriate. A follow-on project could then develop any new standards that are needed, based on the specified requirements.
