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

{
  algorithm: "ITU_BS_1770_1",   algorithm_control: "CORRECT_AUDIO",   correction_gate_level: 1,
  loudness_logging: "LOG",   peak_calculation: "TRUE_PEAK",   target_lkfs: 1.0,
}

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

Returned by:

• Aws::MediaConvert::Types::AudioDescription#audio_normalization_settings

• #algorithm ⇒ 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.

• #correction_gate_level ⇒ 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.

• #peak_calculation ⇒ 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.

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

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

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

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

Possible values:

• LOG
• DONT_LOG

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

Possible values:

• TRUE_PEAK
• NONE

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.
