Dialnorm: History, Applications & Measurement

Dialnorm is the metadata parameter that controls playback gain within the Dolby Laboratories Dolby Digital (AC-3) audio compression system. Dialnorm stands for dialog normalization. Dialnorm is an integer value with range 1 to 31 corresponding to a playback gain of −30 to 0 dB (unity) respectively. Higher values afford more headroom and are appropriate…
