Description
Indicates the acoustic sound pressure level of the dialogue
level during the final audio mixing session.
Type and calibration of the mixing room used for the final
audio mixing session.
Indicates if the material is copyright protected
Indicates if source is the original or a copy
Flags if additional information is available for downmixing.
Indicates if the producer would prefer a Lt/Rt or a Lo/Ro
downmix. Can be over-ridden by the decoder.
Indicates the required level reduction of the center channel
when mixed with the L& R channels for a Lt/Rt downmix.
Similar to 'Center mix level'.
Indicates the required level reduction of the surround
channels when mixed for a Lt/Rt downmix. Similar to
Surround mix level'.
Indicates the required level reduction of the center channel
when mixed with the L& R channels for a Lo/Ro downmix.
When present this replaces the value set for the 'Center
mix level'
Indicates the required level reduction of the center channel
when mixed for Lo/Ro downmix. When present this
replaces the value set for the 'Surround mix level'.
Flags if the stream has been encoded in 'Surround Ex'.
Only used if surround channels are present.
Indicates type of A/D conversion used.
To meet the Dolby Digital encoding algorithm specification
the audio must not have pre-emphasis applied. If the input
signal does have pre-emphasis applied, a de-emphasis
filter must be applied prior to encoding.
Removing the DC component can lead to more efficient
encoding, but there is a risk that signals that do not reach
100% PCM may exceed this after filtering and therefore
must be clipped.
Remove high frequency signals before encoding. The filter
removes frequencies that would not normally be encoded.
Apply a 120 Hz low pass filter prior to an encode. Should
only be switched off if it is known that there are no
frequencies above 120 Hz.
Attenuate surround channels by 3 dB before encoding.
Theatrical and consumer mixing rooms use different levels
for the surround channels, and this can be used to
compensate.
Apply a phase shift of 90 degrees to the surround
channels. This simplifies the decode process for producing
a 'Lt/Rt' downmix.
