#Dolby Srnd EX
Surround EX. This setting is used to identify the encoded audio as
surround EX encoded material. This parameter is only used if the encoded
audio has two surround channels. An amplifier or receiver with Dolby
Digital EX decoding can use this parameter as a flag to switch the
decoding on or off automatically. The behavior is similar to the Dolby
Surround Mode parameter. Not Indic., NotDolbySrnd, DolbySrnd. You
can also choose to use the metadata settings in the external program
(
Ext_meta
, only usable when the
MD_enc1
till
MD_enc4
are set to
MxA
till
MxH
). Default is Not Srnd.
#DC filter
DC filter. This setting determines whether a DC blocking 3Hz highpass
filter is applied to the main inputs channels of a Dolby Digital encoder
prior encoding. This parameter is not carried to the consumer decoder. It
is used to remove DC offsets in the program audio and would only be
switched off in exceptional circumstances. On this function is active, OFF
this function is not active. You can also choose to use the metadata
settings in the external program (
Ext_meta
, only usable when the
MD_enc1
till
MD_enc4
are set to
MxA
till
MxH
). Default is ON.
#LFE filter
LFE lowpass filter. This setting determines whether a 120hZ 8 order
lowpass filter is applied to the LFEE 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 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. On this function is active, OFF this function is
not active. You can also choose to use the metadata settings in the external
program (
Ext_meta
, only usable when the
MD_enc1
till
MD_enc4
are
set to
MxA
till
MxH
). Default is ON.
