Values.Ac3SettingsSourceAc3 Settings
type nonrec t = {bitrate : float option;Average bitrate in bits/second. Valid bitrates depend on the coding mode.
*)bitstreamMode : Ac3BitstreamMode.t option;Specifies the bitstream mode (bsmod) for the emitted AC-3 stream. See ATSC A/52-2012 for background on these values.
*)codingMode : Ac3CodingMode.t option;Dolby Digital coding mode. Determines number of channels.
*)dialnorm : int option;Sets the dialnorm for the output. If excluded and input audio is Dolby Digital, dialnorm will be passed through.
*)drcProfile : Ac3DrcProfile.t option;If set to filmStandard, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.
*)lfeFilter : Ac3LfeFilter.t option;When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid in codingMode32Lfe mode.
*)metadataControl : Ac3MetadataControl.t option;When set to "followInput", encoder metadata will be sourced from the DD, DD+, or DolbyE decoder that supplied this audio data. If audio was not supplied from one of these streams, then the static metadata settings will be used.
*)attenuationControl : Ac3AttenuationControl.t option;Applies a 3 dB attenuation to the surround channels. Applies only when the coding mode parameter is CODING_MODE_3_2_LFE.
