Eac3 Settings
§Properties
When set to attenuate3Db, applies a 3 dB attenuation to the surround channels. Only used for 3/2 coding mode.
Average bitrate in bits/second. Valid bitrates depend on the coding mode.
Specifies the bitstream mode (bsmod) for the emitted E-AC-3 stream. See ATSC A/52-2012 (Annex E) for background on these values.
Dolby Digital Plus coding mode. Determines number of channels.
When set to enabled, activates a DC highpass filter for all input channels.
Sets the dialnorm for the output. If blank and input audio is Dolby Digital Plus, dialnorm will be passed through.
Sets the Dolby dynamic range compression profile.
When encoding 3/2 audio, setting to lfe enables the LFE channel
When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with codingMode32 coding mode.
Left only/Right only center mix level. Only used for 3/2 coding mode.
Left only/Right only surround mix level. Only used for 3/2 coding mode.
Left total/Right total center mix level. Only used for 3/2 coding mode.
Left total/Right total surround mix level. Only used for 3/2 coding mode.
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.
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.
When set to shift90Degrees, applies a 90-degree phase shift to the surround channels. Only used for 3/2 coding mode.
Stereo downmix preference. Only used for 3/2 coding mode.
When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.
When encoding 2/0 audio, sets whether Dolby Surround is matrix encoded into the two channels.
