Properties

NameTypeDescription
attenuationControl?stringWhen set to attenuate3Db, applies a 3 dB attenuation to the surround channels.
bitrate?numberThe average bitrate in bits/second.
bitstreamMode?stringSpecifies the bitstream mode (bsmod) for the emitted E-AC-3 stream.
codingMode?stringThe Dolby Digital Plus coding mode.
dcFilter?stringWhen set to enabled, activates a DC highpass filter for all input channels.
dialnorm?numberSets the dialnorm for the output.
drcLine?stringSets the Dolby dynamic range compression profile.
drcRf?stringSets the profile for heavy Dolby dynamic range compression, ensuring that the instantaneous signal peaks do not exceed specified levels.
lfeControl?stringWhen encoding 3/2 audio, setting to lfe enables the LFE channel.
lfeFilter?stringWhen set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding.
loRoCenterMixLevel?numberThe Left only/Right only center mix level.
loRoSurroundMixLevel?numberThe Left only/Right only surround mix level.
ltRtCenterMixLevel?numberThe Left total/Right total center mix level.
ltRtSurroundMixLevel?numberThe Left total/Right total surround mix level.
metadataControl?stringWhen set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data.
passthroughControl?stringWhen set to whenPossible, input DD+ audio will be passed through if it is present on the input.
phaseControl?stringWhen set to shift90Degrees, applies a 90-degree phase shift to the surround channels.
stereoDownmix?stringA stereo downmix preference.
surroundExMode?stringWhen encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.
surroundMode?stringWhen encoding 2/0 audio, sets whether Dolby Surround is matrix-encoded into the two channels.

attenuationControl?

Type: string (optional)

When set to attenuate3Db, applies a 3 dB attenuation to the surround channels.

Used only for the 3/2 coding mode.


bitrate?

Type: number (optional)

The average bitrate in bits/second.

Valid bitrates depend on the coding mode.


bitstreamMode?

Type: string (optional)

Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream.

For more information, see ATSC A/52-2012 (Annex E).


codingMode?

Type: string (optional)

The Dolby Digital Plus coding mode.

This mode determines the number of channels.


dcFilter?

Type: string (optional)

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


dialnorm?

Type: number (optional)

Sets the dialnorm for the output.

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


drcLine?

Type: string (optional)

Sets the Dolby dynamic range compression profile.


drcRf?

Type: string (optional)

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


lfeControl?

Type: string (optional)

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


lfeFilter?

Type: string (optional)

When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding.

Valid only with a codingMode32 coding mode.


loRoCenterMixLevel?

Type: number (optional)

The Left only/Right only center mix level.

Used only for the 3/2 coding mode.


loRoSurroundMixLevel?

Type: number (optional)

The Left only/Right only surround mix level.

Used only for a 3/2 coding mode.


ltRtCenterMixLevel?

Type: number (optional)

The Left total/Right total center mix level.

Used only for a 3/2 coding mode.


ltRtSurroundMixLevel?

Type: number (optional)

The Left total/Right total surround mix level.

Used only for the 3/2 coding mode.


metadataControl?

Type: string (optional)

When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data.

If the audio is not supplied from one of these streams, then the static metadata settings are used.


passthroughControl?

Type: string (optional)

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.


phaseControl?

Type: string (optional)

When set to shift90Degrees, applies a 90-degree phase shift to the surround channels.

Used only for a 3/2 coding mode.


stereoDownmix?

Type: string (optional)

A stereo downmix preference.

Used only for the 3/2 coding mode.


surroundExMode?

Type: string (optional)

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


surroundMode?

Type: string (optional)

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