@!attribute [rw] attenuation_control

If set to ATTENUATE\_3\_DB, applies a 3 dB attenuation to the
surround channels. Only used for 3/2 coding mode.
@return [String]

@!attribute [rw] bitrate

Specify the average bitrate in bits per second. Valid bitrates
depend on the coding mode.
@return [Integer]

@!attribute [rw] bitstream_mode

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).
@return [String]

@!attribute [rw] coding_mode

Dolby Digital Plus coding mode. Determines number of channels.
@return [String]

@!attribute [rw] dc_filter

Activates a DC highpass filter for all input channels.
@return [String]

@!attribute [rw] dialnorm

Sets the dialnorm for the output. If blank and input audio is Dolby
Digital Plus, dialnorm will be passed through.
@return [Integer]

@!attribute [rw] dynamic_range_compression_line

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 (DynamicRangeCompressionProfile). 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.
@return [String]

@!attribute [rw] dynamic_range_compression_rf

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 (DynamicRangeCompressionProfile). 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.
@return [String]

@!attribute [rw] lfe_control

When encoding 3/2 audio, controls whether the LFE channel is enabled
@return [String]

@!attribute [rw] lfe_filter

Applies a 120Hz lowpass filter to the LFE channel prior to encoding.
Only valid with 3\_2\_LFE coding mode.
@return [String]

@!attribute [rw] lo_ro_center_mix_level

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).
@return [Float]

@!attribute [rw] lo_ro_surround_mix_level

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).
@return [Float]

@!attribute [rw] lt_rt_center_mix_level

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).
@return [Float]

@!attribute [rw] lt_rt_surround_mix_level

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).
@return [Float]

@!attribute [rw] metadata_control

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.
@return [String]

@!attribute [rw] passthrough_control

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.
@return [String]

@!attribute [rw] phase_control

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

@!attribute [rw] sample_rate

This value is always 48000. It represents the sample rate in Hz.
@return [Integer]

@!attribute [rw] stereo_downmix

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).
@return [String]

@!attribute [rw] surround_ex_mode

When encoding 3/2 audio, sets whether an extra center back surround
channel is matrix encoded into the left and right surround channels.
@return [String]

@!attribute [rw] surround_mode

When encoding 2/0 audio, sets whether Dolby Surround is matrix
encoded into the two channels.
@return [String]
