  • When encoding 3/2 audio, controls whether the LFE channel is enabled

    Declaration

    Swift

    public let lfeControl: Eac3LfeControl?

  • Applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with 3_2_LFE coding mode.

    Declaration

    Swift

    public let lfeFilter: Eac3LfeFilter?

  • Specify a value for the following Dolby Digital Plus setting: Left only/Right only center mix (Lo/Ro center). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). Valid values: 3.0, 1.5, 0.0, -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left only/Right only center (loRoCenterMixLevel).

    Declaration

    Swift

    public let loRoCenterMixLevel: Double?

  • Specify a value for the following Dolby Digital Plus setting: Left only/Right only (Lo/Ro surround). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). Valid values: -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left only/Right only surround (loRoSurroundMixLevel).

    Declaration

    Swift

    public let loRoSurroundMixLevel: Double?

  • Specify a value for the following Dolby Digital Plus setting: Left total/Right total center mix (Lt/Rt center). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). Valid values: 3.0, 1.5, 0.0, -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left total/Right total center (ltRtCenterMixLevel).

    Declaration

    Swift

    public let ltRtCenterMixLevel: Double?

  • Specify a value for the following Dolby Digital Plus setting: Left total/Right total surround mix (Lt/Rt surround). MediaConvert uses this value for downmixing. How the service uses this value depends on the value that you choose for Stereo downmix (Eac3StereoDownmix). Valid values: -1.5, -3.0, -4.5, -6.0, and -60. The value -60 mutes the channel. This setting applies only if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Left total/Right total surround (ltRtSurroundMixLevel).

    Declaration

    Swift

    public let ltRtSurroundMixLevel: Double?

  • When set to FOLLOW_INPUT, 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.

    Declaration

    Swift

    public let metadataControl: Eac3MetadataControl?

  • When set to WHEN_POSSIBLE, 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.

    Declaration

    Swift

    public let passthroughControl: Eac3PassthroughControl?

  • Controls the amount of phase-shift applied to the surround channels. Only used for 3/2 coding mode.

    Declaration

    Swift

    public let phaseControl: Eac3PhaseControl?

  • This value is always 48000. It represents the sample rate in Hz.

    Declaration

    Swift

    public let sampleRate: Int?

  • Choose how the service does stereo downmixing. This setting only applies if you keep the default value of 3/2 - L, R, C, Ls, Rs (CODING_MODE_3_2) for the setting Coding mode (Eac3CodingMode). If you choose a different value for Coding mode, the service ignores Stereo downmix (Eac3StereoDownmix).

    Declaration

    Swift

    public let stereoDownmix: Eac3StereoDownmix?

  • When encoding 3/2 audio, sets whether an extra center back surround channel is matrix encoded into the left and right surround channels.

    Declaration
