Eac3Settings Structure Reference
Eac3Settings
public struct Eac3Settings : AWSShapeUndocumented
-
Declaration
Swift
public static var _members: [AWSShapeMember] -
When set to attenuate3Db, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.
Declaration
Swift
public let attenuationControl: Eac3AttenuationControl? -
Average bitrate in bits/second. Valid bitrates depend on the coding mode.
Declaration
Swift
public let bitrate: Double? -
Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. See ATSC A/52-2012 (Annex E) for background on these values.
Declaration
Swift
public let bitstreamMode: Eac3BitstreamMode? -
Dolby Digital Plus coding mode. Determines number of channels.
Declaration
Swift
public let codingMode: Eac3CodingMode? -
When set to enabled, activates a DC highpass filter for all input channels.
Declaration
Swift
public let dcFilter: Eac3DcFilter? -
Sets the dialnorm for the output. If blank and input audio is Dolby Digital Plus, dialnorm will be passed through.
Declaration
Swift
public let dialnorm: Int? -
Sets the Dolby dynamic range compression profile.
Declaration
Swift
public let drcLine: Eac3DrcLine? -
Sets the profile for heavy Dolby dynamic range compression, ensures that the instantaneous signal peaks do not exceed specified levels.
Declaration
Swift
public let drcRf: Eac3DrcRf? -
When encoding 3/2 audio, setting to lfe enables the LFE channel
Declaration
Swift
public let lfeControl: Eac3LfeControl? -
When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with codingMode32 coding mode.
Declaration
Swift
public let lfeFilter: Eac3LfeFilter? -
Left only/Right only center mix level. Only used for 3/2 coding mode.
Declaration
Swift
public let loRoCenterMixLevel: Double? -
Left only/Right only surround mix level. Only used for 3/2 coding mode.
Declaration
Swift
public let loRoSurroundMixLevel: Double? -
Left total/Right total center mix level. Only used for 3/2 coding mode.
Declaration
Swift
public let ltRtCenterMixLevel: Double? -
Left total/Right total surround mix level. Only used for 3/2 coding mode.
Declaration
Swift
public let ltRtSurroundMixLevel: Double? -
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.
Declaration
Swift
public let metadataControl: Eac3MetadataControl? -
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.
Declaration
Swift
public let passthroughControl: Eac3PassthroughControl? -
When set to shift90Degrees, applies a 90-degree phase shift to the surround channels. Only used for 3/2 coding mode.
Declaration
Swift
public let phaseControl: Eac3PhaseControl? -
Stereo downmix preference. Only used for 3/2 coding mode.
Declaration
Swift
public let stereoDownmix: Eac3StereoDownmix? -
When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.
Declaration
Swift
public let surroundExMode: Eac3SurroundExMode? -
When encoding 2/0 audio, sets whether Dolby Surround is matrix encoded into the two channels.
Declaration
Swift
public let surroundMode: Eac3SurroundMode? -
