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] and also suitable for China Multimedia Mobile Broadcasting and DVB-H as extensively addressed in the International Journal of Digital Multimedia Broadcasting.

It is one of the standard formats for Blu-ray Disc audio, introduced with Blu-ray Disc 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.
