Lo/Ro preferred
: Left only/Right only. The Lo/Ro downmix
discretely adds the Left and Right Surround channels to the Left
and Right speaker channels, respectively. This preserves stereo
separation for stereo-only monitoring and produces a
monocompatible signal.
The LFE channel is not included in any downmixes.
Lt/Rt center downmix level (multi-channel only)
: level shift
applied to the Center channel when adding to the left and right
outputs as a result of downmixing to an Lt/Rt output, in decibels.
Lt/Rt surround downmix level (multi-channel only)
: level shift
applied to the Surround channels when downmixing to an Lt/Rt
output, in decibels.
Lo/Ro center downmix level (multi-channel only)
: level shift
applied to the Center channel when adding to the left and right
outputs as a result of downmixing to an Lo/Ro output, in decibels.
Lo/Ro surround downmix level (multi-channel only)
: level
shift applied to the Surround channels when downmixing to an Lo/Ro
output, in decibels.
Dolby surround mode (stereo only)
: indicates whether the
stereo audio is Dolby® Surround encoded or not. The value is not
taken into account in 1/0 mode.
Dialogue normalisation
: average dialog level, in decibels.
DC highpass filter
: set to
true
to enable the high pass filter on the
input audio samples.
Copyright bit
: set to
true
if the encoded Dolby® Digital bitstream is
copyright protected.
Original bitstream
: set to
true
if the encoded Dolby® Digital
bitstream is the master version or to
false
if it is a copy.
LFE channel filter
: set to
true
to enable a 120 Hz filter. The 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. The filter
removes frequencies above 120 Hz that would cause aliasing when
decoded. This filter should only be switched off if the audio to be
encoded is known not to have any signals above 120 Hz.
Surround 3 dB attenuation
: set to
true
to apply a 3 dB attenuation
before encoding the Surround channel(s).
Surround phase shift
: set to
true
to apply a 90-degree phase shift
to the Surround channels. The Dolby® Digital decoder can therefore
easily create an Lt/Rt downmix.
