AES42-2010 AES standard for acoustics —Digital interface for microphones has been published. This standard revises and updates AES42-2006.
The main addition to this standard is the AES42 system-command set to enable storage and recall of user settings in the microphone itself.
Additionally a new feature has been introduced: Since the upload times were not acceptable for a firmware update using the AES42 interface the bit rate can now be increased. This higher bit rate, called Fast-DPP mode, can be used to transmit DPP commands or firmware update data. It is introduced as an option.
Furthermore an optional periodic transmission control feature is introduced to allow manufacturer specific command sets for remote control of microphone features.
