Don't miss the point that (IIRC...) Dolby Digital (AC3) decoders are able to use metadata in the bitstream to know immediately recommended values already stored by the encoder. May they just be the exponent of a floating point representation of loudness or DialNorm values, or even respect acoustic room models set up in the AC3 encoder, I am not sure; but there is definitely an advantage over dynamic range control for unexpected miscellaneous audio which requires a look-ahead window and introduces a latency.
