Dynamic Resolution Adaptation

Dynamic Resolution Adaptation (DRA) is an audio encoding specification developed by DigiRise Technology. It has been selected as the Chinese national audio coding standard.^[1]

It is one of the standard formats for Blu-Ray audio, introduced with Blu-Ray 2.3.^[2] There are no discs as yet released with DRA audio, though there are expected to be such discs for the Chinese market.
