9. Dialog Normalization

Dialog Normalization is the use of metadata to control playback level. It has no effect on encoding or decoding. It is an instruction to playback equipment to adjust the level of all channels, post-decoding.

A single DIALNORM value is applied to a given program: level is not adjusted within a program. There is no compression involved. All channels are affected equally. DIALNORM can only attenuate.

The DIALNORM value entered into the encoder is the subjective average dialog level of the program, not the amount of playback attenuation. The subjective average dialog level is typically approximated by LeqA measurement. The correspondence between DIALNORM value and attenuation is given in the following table.

DIALNORM value	Attenuation	DIALNORM value	Attenuation
(dialogue level, dBFS LeqA)	(dB)	(dialogue level, dBFS LeqA)	(dB)
