Bases: object

(experimental) Properties for AC3 codec settings.

Parameters:

attenuation_control (Optional[Ac3AttenuationControl]) – (experimental) Applies a 3 dB attenuation to the surround channels. Used only for the 3/2 coding mode. Default: - service default
bitrate (Optional[Bitrate]) – (experimental) The average bitrate. Default: - service default
bitstream_mode (Optional[Ac3BitstreamMode]) – (experimental) Specifies the bitstream mode (bsmod) for the emitted AC-3 stream. Default: Ac3BitstreamMode.COMPLETE_MAIN
coding_mode (Optional[Ac3CodingMode]) – (experimental) The Dolby Digital coding mode. Default: Ac3CodingMode.CODING_MODE_2_0
dial_norm (Union[int, float, None]) – (experimental) The dialogue normalization level (1–31). Default: - service default
drc_profile (Optional[Ac3DrcProfile]) – (experimental) If set to filmStandard, adds dynamic range compression signaling to the output bitstream. Default: - service default
lfe_filter (Optional[Ac3LfeFilter]) – (experimental) When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Valid only in codingMode32Lfe mode. Default: Ac3LfeFilter.DISABLED
metadata_control (Optional[Ac3MetadataControl]) – (experimental) When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data. Default: - service default
