Overview

Note:

When passing AudioNormalizationSettings as input to an Aws::Client method, you can use a vanilla Hash:

{
  algorithm: "ITU_BS_1770_1", # accepts ITU_BS_1770_1, ITU_BS_1770_2, ITU_BS_1770_3, ITU_BS_1770_4
  algorithm_control: "CORRECT_AUDIO", # accepts CORRECT_AUDIO, MEASURE_ONLY
  correction_gate_level: 1,
  loudness_logging: "LOG", # accepts LOG, DONT_LOG
  peak_calculation: "TRUE_PEAK", # accepts TRUE_PEAK, NONE
  target_lkfs: 1.0,
}

Advanced audio normalization settings. Ignore these settings unless you need to comply with a loudness standard.

Instance Attribute Details

#algorithm ⇒ String

Choose one of the following audio normalization algorithms: ITU-R BS.1770-1: Ungated loudness. A measurement of ungated average loudness for an entire piece of content, suitable for measurement of short-form content under ATSC recommendation A/85. Supports up to 5.1 audio channels. ITU-R BS.1770-2: Gated loudness. A measurement of gated average loudness compliant with the requirements of EBU-R128. Supports up to 5.1 audio channels. ITU-R BS.1770-3: Modified peak. The same loudness measurement algorithm as 1770-2, with an updated true peak measurement. ITU-R BS.1770-4: Higher channel count. Allows for more audio channels than the other algorithms, including configurations such as 7.1.

Possible values:

  • ITU_BS_1770_1
  • ITU_BS_1770_2
  • ITU_BS_1770_3
  • ITU_BS_1770_4

Returns:

  • (String) —

    Choose one of the following audio normalization algorithms: ITU-R BS.1770-1: Ungated loudness.

#algorithm_control ⇒ String

When enabled the output audio is corrected using the chosen algorithm. If disabled, the audio will be measured but not adjusted.

Possible values:

  • CORRECT_AUDIO
  • MEASURE_ONLY

Returns:

  • (String) —

    When enabled the output audio is corrected using the chosen algorithm.

#correction_gate_level ⇒ Integer

Content measuring above this level will be corrected to the target level. Content measuring below this level will not be corrected.

Returns:

  • (Integer) —

    Content measuring above this level will be corrected to the target level.

#loudness_logging ⇒ String

If set to LOG, log each output\'s audio track loudness to a CSV file.

Possible values:

  • LOG
  • DONT_LOG

Returns:

  • (String) —

    If set to LOG, log each output\'s audio track loudness to a CSV file.

#peak_calculation ⇒ String

If set to TRUE_PEAK, calculate and log the TruePeak for each output\'s audio track loudness.

Possible values:

  • TRUE_PEAK
  • NONE

Returns:

  • (String) —

    If set to TRUE_PEAK, calculate and log the TruePeak for each output\'s audio track loudness.

#target_lkfs ⇒ Float

When you use Audio normalization (AudioNormalizationSettings), optionally use this setting to specify a target loudness. If you don\'t specify a value here, the encoder chooses a value for you, based on the algorithm that you choose for Algorithm (algorithm). If you choose algorithm 1770-1, the encoder will choose -24 LKFS; otherwise, the encoder will choose -23 LKFS.

Returns:

  • (Float) —

    When you use Audio normalization (AudioNormalizationSettings), optionally use this setting to specify a target loudness.
