Eac3Settings

Gets and sets the property AttenuationControl. If set to ATTENUATE_3_DB, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.

Gets and sets the property Bitrate. Specify the average bitrate in bits per second. The bitrate that you specify must be a multiple of 8000 within the allowed minimum and maximum values. Leave blank to use the default bitrate for the coding mode you select according ETSI TS 102 366. Valid bitrates for coding mode 1/0: Default: 96000. Minimum: 32000. Maximum: 3024000. Valid bitrates for coding mode 2/0: Default: 192000. Minimum: 96000. Maximum: 3024000. Valid bitrates for coding mode 3/2: Default: 384000. Minimum: 192000. Maximum: 3024000.

Gets and sets the property BitstreamMode. Specify the bitstream mode for the E-AC-3 stream that the encoder emits. For more information about the EAC3 bitstream mode, see ATSC A/52-2012 (Annex E).

Gets and sets the property CodingMode. Dolby Digital Plus coding mode. Determines number of channels.

Gets and sets the property DcFilter. Activates a DC highpass filter for all input channels.

Gets and sets the property Dialnorm. Sets the dialnorm for the output. If blank and input audio is Dolby Digital Plus, dialnorm will be passed through.

Gets and sets the property DynamicRangeCompressionLine. Choose the Dolby Digital dynamic range control (DRC) profile that MediaConvert uses when encoding the metadata in the Dolby Digital stream for the line operating mode. Related setting: When you use this setting, MediaConvert ignores any value you provide for Dynamic range compression profile. For information about the Dolby Digital DRC operating modes and profiles, see the Dynamic Range Control chapter of the Dolby Metadata Guide at https://developer.dolby.com/globalassets/professional/documents/dolby-metadata-guide.pdf.

Gets and sets the property DynamicRangeCompressionRf. Choose the Dolby Digital dynamic range control (DRC) profile that MediaConvert uses when encoding the metadata in the Dolby Digital stream for the RF operating mode. Related setting: When you use this setting, MediaConvert ignores any value you provide for Dynamic range compression profile. For information about the Dolby Digital DRC operating modes and profiles, see the Dynamic Range Control chapter of the Dolby Metadata Guide at https://developer.dolby.com/globalassets/professional/documents/dolby-metadata-guide.pdf.

Gets and sets the property LfeControl. When encoding 3/2 audio, controls whether the LFE channel is enabled

Gets and sets the property LfeFilter. Applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with 3_2_LFE coding mode.

Gets and sets the property LoRoCenterMixLevel. Specify a value for the following Dolby Digital Plus setting: Left only/Right only center mix. MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix. Valid values: 3.0, 1.5, 0.0, -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs for the setting Coding mode. If you choose a different value for Coding mode, the service ignores Left only/Right only center.

Gets and sets the property LoRoSurroundMixLevel. Specify a value for the following Dolby Digital Plus setting: Left only/Right only. MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix. Valid values: -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs for the setting Coding mode. If you choose a different value for Coding mode, the service ignores Left only/Right only surround.

Gets and sets the property LtRtCenterMixLevel. Specify a value for the following Dolby Digital Plus setting: Left total/Right total center mix. MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix. Valid values: 3.0, 1.5, 0.0, -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs for the setting Coding mode. If you choose a different value for Coding mode, the service ignores Left total/Right total center.

Gets and sets the property LtRtSurroundMixLevel. Specify a value for the following Dolby Digital Plus setting: Left total/Right total surround mix. MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix. Valid values: -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs for the setting Coding mode. If you choose a different value for Coding mode, the service ignores Left total/Right total surround.

Gets and sets the property MetadataControl. When set to FOLLOW_INPUT, 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.

Gets and sets the property PassthroughControl. When set to WHEN_POSSIBLE, 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.

Gets and sets the property PhaseControl. Controls the amount of phase-shift applied to the surround channels. Only used for 3/2 coding mode.

Gets and sets the property SampleRate. This value is always 48000. It represents the sample rate in Hz.

Gets and sets the property StereoDownmix. Choose how the service does stereo downmixing. This setting only applies if you keep the default value of 3/2 - L, R, C, Ls, Rs for the setting Coding mode. If you choose a different value for Coding mode, the service ignores Stereo downmix.

Gets and sets the property SurroundExMode. When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.

Gets and sets the property SurroundMode. When encoding 2/0 audio, sets whether Dolby Surround is matrix encoded into the two channels.
