| Dialnorm is used in film sound mixing and describes the normalization of the dialog loudness level (dialogue normalisation) with respect to a certain reference monitoring level (-31 dBFS in surround applications). The idea behind this scheme is that the perceived total loudness of a mixed audio signal may be determined and kept constant at the listening end by using the dialogue level (optimized for a combination of good intelligibility and minimal nuisance through excessive volumes) with its fixed loudness ratio in relation to music and sound effects as a reference. |
