type nonrec t = {attenuationControl : Eac3AttenuationControl.t option;When set to attenuate3Db, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.
*)bitrate : float option;Average bitrate in bits/second. Valid bitrates depend on the coding mode.
*)bitstreamMode : Eac3BitstreamMode.t option;Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. See ATSC A/52-2012 (Annex E) for background on these values.
*)codingMode : Eac3CodingMode.t option;Dolby Digital Plus coding mode. Determines number of channels.
*)dcFilter : Eac3DcFilter.t option;When set to enabled, activates a DC highpass filter for all input channels.
*)dialnorm : int option;Sets the dialnorm for the output. If blank and input audio is Dolby Digital Plus, dialnorm will be passed through.
*)drcLine : Eac3DrcLine.t option;Sets the Dolby dynamic range compression profile.
*)drcRf : Eac3DrcRf.t option;Sets the profile for heavy Dolby dynamic range compression, ensures that the instantaneous signal peaks do not exceed specified levels.
*)lfeControl : Eac3LfeControl.t option;When encoding 3/2 audio, setting to lfe enables the LFE channel
*)lfeFilter : Eac3LfeFilter.t option;When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with codingMode32 coding mode.
*)loRoCenterMixLevel : float option;Left only/Right only center mix level. Only used for 3/2 coding mode.
*)loRoSurroundMixLevel : float option;Left only/Right only surround mix level. Only used for 3/2 coding mode.
*)ltRtCenterMixLevel : float option;Left total/Right total center mix level. Only used for 3/2 coding mode.
*)ltRtSurroundMixLevel : float option;Left total/Right total surround mix level. Only used for 3/2 coding mode.
*)metadataControl : Eac3MetadataControl.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.
*)passthroughControl : Eac3PassthroughControl.t option;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.
*)phaseControl : Eac3PhaseControl.t option;When set to shift90Degrees, applies a 90-degree phase shift to the surround channels. Only used for 3/2 coding mode.
*)stereoDownmix : Eac3StereoDownmix.t option;Stereo downmix preference. Only used for 3/2 coding mode.
*)surroundExMode : Eac3SurroundExMode.t option;When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.
*)surroundMode : Eac3SurroundMode.t option;When encoding 2/0 audio, sets whether Dolby Surround is matrix encoded into the two channels.
