#ProdMixLvl
The audio production mixing level parameter describes the peak sound pressure
level (SPL) used during the final mixing session at the studio or on the dubbing
stage. The parameter allows an amplifier to set its volume control such that the
SPL in the replay environment matches that of the mixing room. This control
operates in addition to the dialogue level control, and is best thought of as the
final volume setting on the consumer’s equipment.
This value can be determined by measuring the SPL of pink noise at studio
reference level and then adding the amount of digital headroom above that level.
For example, if 85 dB equates to a reference level of -20 dBFS, the mixing level is
85 + 20, i.e. 105 dB. Can be set to any value between 80 and 111 dB. This item will
only influence the output if #Prod_Mix_LvlSrc is set to
Int_Meta
.
The default setting is
0
.
#ProdRoomType
The Room Type parameter describes the equalization used during the final mixing
session at the studio or on the dubbing stage. A
Large
room is a dubbing stage
with the industry standard X-curve equalization; a
Small
room has flat
equalization. This parameter allows an amplifier to be set to the same equalization
as that heard in the final mixing environment. Can also be set to
Not Indicated
or
to use the metadata settings in the external program (Ext_meta).
#LFE_Filter
This setting determines whether a 120Hz 8 order lowpass filter is applied to the
LFE channel input of a Dolby Digital encoder prior to encoding. It is ignored if the
LFE channel is disabled. This parameter is not sent to the consumer decoder. The
filter removes frequencies above 120Hz that would prevent aliasing when
decoded. This filter should only be switched off if the audio to be encoded is
known to have no signal above 120 Hz. Options are
On
(active) or
OFF
(not
active).
You can also choose to use the metadata settings in the external program (Ext_
meta). Default is Ext_meta.
#AC3OrigBitstr
AC3 original bitstream. Here you set whether the incoming signal is of the original
master bitrate (yes) or if it has been converted before (no).
You can also choose to use the metadata settings in the external program (Ext_
meta).
#Pref_Dwnmx
Preferred Down mix. This parameter allows the user to select either Lt/Rt or the
Lo/Ro downmix in a consumer decoder that has stereo outputs. Consumer
receivers are able to override this selection, but this parameter provides the
opportunity for a 5.1 channel soundtrack to play in Lo/Ro mode without user
intervention. This is especially useful on music material. The possible mix types
are
NOT indicated
,
Lt/Rt
and
Lo/Ro
.
You can also choose to use the metadata settings in the external program (Ext_
meta). Default is Ext_meta.
