AES3-am5-2008, Amendment 5 to AES standard for digital audio - Digital input-output interfacing - Serial transmission format for two channel linearly represented digital audio data, has been published 2008-04-19. Recent projects to support carriage of MPEG Surround data in an AES3 bitstream (see AES55-2007), as well as questions arising when considering non-PCM data in an AES3 signal, require some detailed changes to the AES3 specification. 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.
