Instance Attribute Details #attenuation_control ⇒ String

When set to attenuate3Db, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.

Possible values:

ATTENUATE_3_DB
NONE

#bitrate ⇒ Float

Average bitrate in bits/second. Valid bitrates depend on the coding mode.

#bitstream_mode ⇒ String

Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. See ATSC A/52-2012 (Annex E) for background on these values.

Possible values:

COMMENTARY
COMPLETE_MAIN
EMERGENCY
HEARING_IMPAIRED
VISUALLY_IMPAIRED

#coding_mode ⇒ String

Dolby Digital Plus coding mode. Determines number of channels.

Possible values:

CODING_MODE_1_0
CODING_MODE_2_0
CODING_MODE_3_2

#dc_filter ⇒ String

When set to enabled, activates a DC highpass filter for all input channels.

Possible values:

DISABLED
ENABLED

#dialnorm ⇒ Integer

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

#drc_line ⇒ String

Sets the Dolby dynamic range compression profile.

Possible values:

FILM_LIGHT
FILM_STANDARD
MUSIC_LIGHT
MUSIC_STANDARD
NONE
SPEECH

#drc_rf ⇒ String

Sets the profile for heavy Dolby dynamic range compression, ensures that the instantaneous signal peaks do not exceed specified levels.

Possible values:

FILM_LIGHT
FILM_STANDARD
MUSIC_LIGHT
MUSIC_STANDARD
NONE
SPEECH

#lfe_control ⇒ String

When encoding 3/2 audio, setting to lfe enables the LFE channel

Possible values:

LFE
NO_LFE

#lfe_filter ⇒ String

When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with codingMode32 coding mode.

Possible values:

DISABLED
ENABLED

#lo_ro_center_mix_level ⇒ Float

Left only/Right only center mix level. Only used for 3/2 coding mode.

#lo_ro_surround_mix_level ⇒ Float

Left only/Right only surround mix level. Only used for 3/2 coding mode.

#lt_rt_center_mix_level ⇒ Float

Left total/Right total center mix level. Only used for 3/2 coding mode.

#lt_rt_surround_mix_level ⇒ Float

Left total/Right total surround mix level. Only used for 3/2 coding mode.

#metadata_control ⇒ String

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.

Possible values:

FOLLOW_INPUT
USE_CONFIGURED

#passthrough_control ⇒ String

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.

Possible values:

NO_PASSTHROUGH
WHEN_POSSIBLE

#phase_control ⇒ String

When set to shift90Degrees, applies a 90-degree phase shift to the surround channels. Only used for 3/2 coding mode.

Possible values:

NO_SHIFT
SHIFT_90_DEGREES

#stereo_downmix ⇒ String

Stereo downmix preference. Only used for 3/2 coding mode.

Possible values:

DPL2
LO_RO
LT_RT
NOT_INDICATED

#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:

DISABLED
ENABLED
NOT_INDICATED

#surround_mode ⇒ String

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

Possible values:

DISABLED
ENABLED
NOT_INDICATED
