#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

. Default is 

NotDolbySrnd

. 

 

 

#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. Default is 

On

. 

 

 

#LFE filter 

LFE lowpass 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 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

 (active) or 

OFF

 (not active). Default is 

On

.

   

LFE filter is automatically switched on when ACMOD is 3/2.  

 

 

#Lowpass Filter 

Lowpass Filter. This setting determines whether a lowpass filter is 
applied to the main input channels of a Dolby Digital encoder to encode. 
This filter removes high frequent signals that are not encoded. At the 
suitable data rates this filter operates above 20 kHz. In all cases it 
prevents aliasing on decoding and is normally switched on. This 
parameter is not passed to the consumer decoder. 

On

 this function is 

active, 

OFF

 this function is not active. Default is 

On

.   

 

 

#Srnd 3Db atten 

Surround 3dB attenuation. This setting determines whether the surround 
channels are attenuated 3 dB before encoding. The attenuation actually 
takes place inside the Dolby Digital encoder. It balances the signals 
levels between theatrical mixing rooms (dubbing stages) and consumer 
mixing rooms (dvd or tv studios) Consumer mixing rooms are calibrated 
so that all five main channels are at the same sound pressure level (SPL). 
For compatibility reasons with older film formats, theatrical mixing 
rooms calibrate the surround channels 3dB lower in SPL that the front 
channels. The consequence is that signal levels on tape are 3dB louder. 
Therefore, to convert to a consumer mix from theatrical calibration it is 
necessary to reduce the surround levels by 3dB.  

On

 = this function is 

active, 

OFF =

 this function is not active. Default is 

Off.
