AES3-4-R: (A003-4) Review of AES3-4-2009, AES standard for digital audio - Digital input-output interfacing - Serial transmission format for two-channel linearly represented digital audio data Part 4: Physical and electrical
Project scope: These four documents specify a recommended interface for the serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This Part 4 document specifies the physical and electrical parameters for different media. The transport format defined in part 3 is intended for use with shielded twisted-pair cable of conventional design over distances of up to 100 m without transmission equalization or any special equalization at the receiver and at frame rates of up to 50 kHz. Longer cable lengths and higher frame rates may be used, but with a rapidly increasing requirement for care in cable selection and possible receiver equalization or the use of active repeaters, or both. Provision is made in this standard for adapting the balanced terminals to use 75 Ohm coaxial cable, and transmission by fibre-optic cable is under consideration. The document does not cover connection to any common carrier equipment. In this interface specification, mention is made of an interface for consumer use. The two interfaces are not identical.

AES-X074: (D074) Recommended Practices for Internet Audio Quality Descriptions (IAQUAD)
Project scope: Prepare AES documents to provide descriptor guidelines to rate the audio quality of Internet transmissions. The guidelines for Internet Audio Quality Descriptions (IAQUAD) will be based on specific criteria that can be efficiently measured by audio manufacturers.
