Properties for AC3 codec settings.

Example

// AAC stereo
const aac = medialive.EncodeConfiguration.audio({
  name: 'aac_stereo',
  codec: medialive.AudioCodecSettings.aac({
    bitrate: Bitrate.kbps(192),
    codingMode: medialive.AacCodingMode.CODING_MODE_2_0,
  }),
});

// AC3 5.1
const ac3 = medialive.EncodeConfiguration.audio({
  name: 'ac3_surround',
  codec: medialive.AudioCodecSettings.ac3({
    bitrate: Bitrate.kbps(384),
    codingMode: medialive.Ac3CodingMode.CODING_MODE_3_2_LFE,
  }),
});

Properties

Name	Type	Description
attenuationControl?🔹	Ac3AttenuationControl	Applies a 3 dB attenuation to the surround channels.
bitrate?🔹	Bitrate	The average bitrate.
bitstreamMode?🔹	Ac3BitstreamMode	Specifies the bitstream mode (bsmod) for the emitted AC-3 stream.
codingMode?🔹	Ac3CodingMode	The Dolby Digital coding mode.
dialNorm?🔹	number	The dialogue normalization level (1–31).
drcProfile?🔹	Ac3DrcProfile	If set to filmStandard, adds dynamic range compression signaling to the output bitstream.
lfeFilter?🔹	Ac3LfeFilter	When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding.
metadataControl?🔹	Ac3MetadataControl	When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data.
