#lfe_control ⇒ String

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

Possible values:

#lfe_filter ⇒ String

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

Possible values:

DISABLED

#lo_ro_center_mix_level ⇒ Float

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).

#lo_ro_surround_mix_level ⇒ Float

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).

#lt_rt_center_mix_level ⇒ Float

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).

#lt_rt_surround_mix_level ⇒ Float

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).

#metadata_control ⇒ String

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.

Possible values:

FOLLOW_INPUT
USE_CONFIGURED

#passthrough_control ⇒ String

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.

Possible values:

WHEN_POSSIBLE
NO_PASSTHROUGH

#phase_control ⇒ String

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

Possible values:

SHIFT_90_DEGREES
NO_SHIFT

#sample_rate ⇒ Integer

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

#stereo_downmix ⇒ String

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).

Possible values:

NOT_INDICATED
LO_RO
LT_RT
DPL2

#surround_ex_mode ⇒ String

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

Possible values:

NOT_INDICATED
ENABLED
DISABLED

#surround_mode ⇒ String

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

Possible values:
