Properties

AttenuationControl

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

Required: No

Type: String

Update requires: No interruption

Bitrate

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

Required: No

Type: Number

Update requires: No interruption

BitstreamMode

Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. For more information, see ATSC A/52-2012 (Annex E).

Required: No

Type: String

Update requires: No interruption

CodingMode

The Dolby Digital Plus coding mode. This mode determines the number of channels.

Required: No

Type: String

Update requires: No interruption

DcFilter

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

Required: No

Type: String

Update requires: No interruption

Dialnorm

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

Required: No

Type: Integer

Update requires: No interruption

DrcLine

Sets the Dolby dynamic range compression profile.

Required: No

Type: String

Update requires: No interruption

DrcRf

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

Required: No

Type: String

Update requires: No interruption

LfeControl

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

Required: No

Type: String

Update requires: No interruption

LfeFilter

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

Required: No

Type: String

Update requires: No interruption

LoRoCenterMixLevel

The Left only/Right only center mix level. Used only for the 3/2 coding mode.

Required: No

Type: Number

Update requires: No interruption

LoRoSurroundMixLevel

The Left only/Right only surround mix level. Used only for a 3/2 coding mode.

Required: No

Type: Number

Update requires: No interruption

LtRtCenterMixLevel

The Left total/Right total center mix level. Used only for a 3/2 coding mode.

Required: No

Type: Number

Update requires: No interruption

LtRtSurroundMixLevel

The Left total/Right total surround mix level. Used only for the 3/2 coding mode.

Required: No

Type: Number

Update requires: No interruption

MetadataControl

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.

Required: No

Type: String

Update requires: No interruption

PassthroughControl

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.

Required: No

Type: String

Update requires: No interruption

PhaseControl

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

Required: No

Type: String

Update requires: No interruption

StereoDownmix

A stereo downmix preference. Used only for the 3/2 coding mode.

Required: No

Type: String

Update requires: No interruption

SurroundExMode

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

Required: No

Type: String

Update requires: No interruption

SurroundMode

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

Required: No

Type: String

Update requires: No interruption
