The settings for an AC3 audio encode in the output.

The parent of this entity is AudioCodecSettings.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_medialive as medialive } from 'aws-cdk-lib';
const ac3SettingsProperty: medialive.CfnChannel.Ac3SettingsProperty = {
  bitrate: 123,
  bitstreamMode: 'bitstreamMode',
  codingMode: 'codingMode',
  dialnorm: 123,

  lfeFilter: 'lfeFilter',
  metadataControl: 'metadataControl',
};

Properties

NameTypeDescription
bitrate?numberThe average bitrate in bits/second.
bitstreamMode?stringSpecifies the bitstream mode (bsmod) for the emitted AC-3 stream.
codingMode?stringThe Dolby Digital coding mode.
dialnorm?numberSets the dialnorm for the output.
drcProfile?stringIf set to filmStandard, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.
lfeFilter?stringWhen set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding.
metadataControl?stringWhen set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data.

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 AC-3 stream.

For more information about these values, see ATSC A/52-2012.


codingMode?

Type: string (optional)

The Dolby Digital coding mode.

This determines the number of channels.


dialnorm?

Type: number (optional)

Sets the dialnorm for the output.

If excluded and the input audio is Dolby Digital, dialnorm is passed through.


drcProfile?

Type: string (optional)

If set to filmStandard, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.


lfeFilter?

Type: string (optional)

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

This is valid only in codingMode32Lfe 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 supplied from one of these streams, the static metadata settings are used.
