Constructor Details

#initialize(attenuation_control: nil, bitrate: nil, bitstream_mode: nil, coding_mode: nil, dialnorm: nil, drc_profile: nil, lfe_filter: nil, metadata_control: nil) ⇒ Ac3SettingsProperty

Returns a new instance of Ac3SettingsProperty.

Parameters:

  • attenuation_control (String, nil) (defaults to: nil)
  • bitrate (Numeric, nil) (defaults to: nil) —

    The average bitrate in bits/second.

  • bitstream_mode (String, nil) (defaults to: nil) —

    Specifies the bitstream mode (bsmod) for the emitted AC-3 stream.

  • coding_mode (String, nil) (defaults to: nil) —

    The Dolby Digital coding mode.

  • dialnorm (Numeric, nil) (defaults to: nil) —

    Sets the dialnorm for the output.

  • drc_profile (String, nil) (defaults to: nil) —

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

  • lfe_filter (String, nil) (defaults to: nil) —

    When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding.

  • metadata_control (String, nil) (defaults to: nil) —

    When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data.

#bitstream_mode ⇒ String? (readonly)

Specifies the bitstream mode (bsmod) for the emitted AC-3 stream.

For more information about these values, see ATSC A/52-2012.

Returns:

  • (String, nil)

#coding_mode ⇒ String? (readonly)

The Dolby Digital coding mode.

This determines the number of channels.

Returns:

  • (String, nil)

#dialnorm ⇒ Numeric? (readonly)

Sets the dialnorm for the output.

If excluded and the input audio is Dolby Digital, dialnorm is passed through.

Returns:

  • (Numeric, nil)
