Properties

var attenuationControl: Ac3AttenuationControl?

Applies a 3 dB attenuation to the surround channels. Applies only when the coding mode parameter is CODING_MODE_3_2_LFE.

bitrate

var bitrate: Double?

Average bitrate in bits/second. Valid bitrates depend on the coding mode.

bitstreamMode

var bitstreamMode: Ac3BitstreamMode?

Specifies the bitstream mode (bsmod) for the emitted AC-3 stream. See ATSC A/52-2012 for background on these values.

codingMode

var codingMode: Ac3CodingMode?

Dolby Digital coding mode. Determines number of channels.

dialnorm

var dialnorm: Int?

Sets the dialnorm for the output. If excluded and input audio is Dolby Digital, dialnorm will be passed through.

drcProfile

var drcProfile: Ac3DrcProfile?

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

lfeFilter

var lfeFilter: Ac3LfeFilter?

When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid in codingMode32Lfe mode.

metadataControl

var metadataControl: Ac3MetadataControl?

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.
