An emerging new AES standard that’s an extension of the current AES3 digital audio interface standard. AES42-2001 provides for interfacing digital microphones and includes the ability to transmit and receive a great deal of data along with the digital audio signals. For example, a user of a digital microphone will be able to remotely control parameters such as polar pattern, pre-attenuation, low cut filter, pre-amplification, mute, and polarity in addition to getting feedback about signal levels and the status of the mic.
