Properties

attenuationControl → Eac3AttenuationControl?
When set to attenuate3Db, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.
final
bitrate → double?
Average bitrate in bits/second. Valid bitrates depend on the coding mode.
final
bitstreamMode → Eac3BitstreamMode?
Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. See ATSC A/52-2012 (Annex E) for background on these values.
final
codingMode → Eac3CodingMode?
Dolby Digital Plus coding mode. Determines number of channels.
final
dcFilter → Eac3DcFilter?
When set to enabled, activates a DC highpass filter for all input channels.
final
dialnorm → int?
Sets the dialnorm for the output. If blank and input audio is Dolby Digital Plus, dialnorm will be passed through.
final
drcLine → Eac3DrcLine?
Sets the Dolby dynamic range compression profile.
final
drcRf → Eac3DrcRf?
Sets the profile for heavy Dolby dynamic range compression, ensures that the instantaneous signal peaks do not exceed specified levels.
final
hashCode → int
The hash code for this object.
no setterinherited
lfeControl → Eac3LfeControl?
When encoding 3/2 audio, setting to lfe enables the LFE channel
final
lfeFilter → Eac3LfeFilter?
When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with codingMode32 coding mode.
final
loRoCenterMixLevel → double?
Left only/Right only center mix level. Only used for 3/2 coding mode.
final
loRoSurroundMixLevel → double?
Left only/Right only surround mix level. Only used for 3/2 coding mode.
final
ltRtCenterMixLevel → double?
Left total/Right total center mix level. Only used for 3/2 coding mode.
final
ltRtSurroundMixLevel → double?
Left total/Right total surround mix level. Only used for 3/2 coding mode.
final
metadataControl → Eac3MetadataControl?
When set to followInput, encoder metadata will be sourced from the DD, DD+, or DolbyE decoder that supplied this audio data. If audio was not supplied from one of these streams, then the static metadata settings will be used.
final
passthroughControl → Eac3PassthroughControl?
When set to whenPossible, input DD+ audio will be passed through if it is present on the input. This detection is dynamic over the life of the transcode. Inputs that alternate between DD+ and non-DD+ content will have a consistent DD+ output as the system alternates between passthrough and encoding.
final
phaseControl → Eac3PhaseControl?
When set to shift90Degrees, applies a 90-degree phase shift to the surround channels. Only used for 3/2 coding mode.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stereoDownmix → Eac3StereoDownmix?
Stereo downmix preference. Only used for 3/2 coding mode.
final
surroundExMode → Eac3SurroundExMode?
When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.
final
surroundMode → Eac3SurroundMode?
When encoding 2/0 audio, sets whether Dolby Surround is matrix encoded into the two channels.
final
