Fields

preferred_downmix_type: u32

Type of downmix preferred by the mastering engineer.

center_mix_level: f64

Absolute scale factor representing the nominal level of the center channel during a regular downmix.

center_mix_level_ltrt: f64

Absolute scale factor representing the nominal level of the center channel during an Lt/Rt compatible downmix.

surround_mix_level: f64

Absolute scale factor representing the nominal level of the surround channels during a regular downmix.

surround_mix_level_ltrt: f64

Absolute scale factor representing the nominal level of the surround channels during an Lt/Rt compatible downmix.

lfe_mix_level: f64

Absolute scale factor representing the level at which the LFE data is mixed into L/R channels during downmixing.
