Properties

attenuationControl → Eac3AttenuationControl?

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

final

bitrate → int?

Specify the average bitrate in bits per second. Valid bitrates depend on the coding mode.

final

bitstreamMode → Eac3BitstreamMode?

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).

final

codingMode → Eac3CodingMode?

Dolby Digital Plus coding mode. Determines number of channels.

final

dcFilter → Eac3DcFilter?

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

dynamicRangeCompressionLine → Eac3DynamicRangeCompressionLine?

Specify the absolute peak level for a signal with dynamic range compression.

final

dynamicRangeCompressionRf → Eac3DynamicRangeCompressionRf?

Specify how the service limits the audio dynamic range when compressing the audio.

final

hashCode → int

The hash code for this object.

no setter, inherited

lfeControl → Eac3LfeControl?

When encoding 3/2 audio, controls whether the LFE channel is enabled

final

lfeFilter → Eac3LfeFilter?

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

final

loRoCenterMixLevel → double?

Specify a value for the following Dolby Digital Plus setting: Left only/Right only center mix (Lo/Ro center). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). 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 (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left only/Right only center (loRoCenterMixLevel).

final

loRoSurroundMixLevel → double?

Specify a value for the following Dolby Digital Plus setting: Left only/Right only (Lo/Ro surround). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). 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 (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left only/Right only surround (loRoSurroundMixLevel).

final

ltRtCenterMixLevel → double?

Specify a value for the following Dolby Digital Plus setting: Left total/Right total center mix (Lt/Rt center). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). 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 (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left total/Right total center (ltRtCenterMixLevel).

final

ltRtSurroundMixLevel → double?

Specify a value for the following Dolby Digital Plus setting: Left total/Right total surround mix (Lt/Rt surround). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). 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 (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left total/Right total surround (ltRtSurroundMixLevel).

final

metadataControl → Eac3MetadataControl?

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.

final

passthroughControl → Eac3PassthroughControl?

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.

final

phaseControl → Eac3PhaseControl?

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

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sampleRate → int?

This value is always 48000. It represents the sample rate in Hz.

final

stereoDownmix → Eac3StereoDownmix?

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 (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Stereo downmix (Eac3StereoDownmix).

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
