AES66-2012, AES standard for professional audio equipment - Application of connectors - Miniature XLR-type polarity and gender, has been published.
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.

AES65-2012, AES standard for interconnections - Connector for surround microphones, has been published.
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.

AES-1id-2012, AES Information Document for Acoustics - Plane-Wave Tubes - Design and Practice, has been published
The standard AES2 calls for the use of plane-wave tube measurement of high-frequency horn drivers. Because many variations and results are possible, depending on the details of construction of plane-wave tubes, this document discusses those variations for the purpose of encouraging further experimentation.
This 2012 edition is a revision of AES 1id-1991. Additional uses of a plane-wave tube are listed. Further tests were performed to compare a distant microphone location with a close location to test the hypothesis that non-plane-wave radiation would be more accurately measured. A termination method is described. A modern method of calibration is referenced and summarized.
