# AudioNormalizationSettings

Audio normalization settings.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/encode-configuration.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/encode-configuration.ts#L237)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as medialive_alpha from '@aws-cdk/aws-medialive-alpha';

declare const audioNormalizationAlgorithm: medialive_alpha.AudioNormalizationAlgorithm;
declare const audioNormalizationAlgorithmControl: medialive_alpha.AudioNormalizationAlgorithmControl;
declare const audioNormalizationPeakCalculation: medialive_alpha.AudioNormalizationPeakCalculation;
const audioNormalizationSettings: medialive_alpha.AudioNormalizationSettings = {
  algorithm: audioNormalizationAlgorithm,
  algorithmControl: audioNormalizationAlgorithmControl,
  peakCalculation: audioNormalizationPeakCalculation,
  peakLimiterThreshold: 123,
  targetLkfs: 123,
};
```

## Properties

- `algorithm`: [AudioNormalizationAlgorithm](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.AudioNormalizationAlgorithm.html) — The normalization algorithm.

  **Default:** service default

- `algorithmControl`: [AudioNormalizationAlgorithmControl](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.AudioNormalizationAlgorithmControl.html) — Whether to correct or only measure.

  **Default:** service default

- `peakCalculation`: [AudioNormalizationPeakCalculation](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.AudioNormalizationPeakCalculation.html) — Whether to use a peak limiter and how to calculate peak levels.

  **Default:** service default

- `peakLimiterThreshold`: number — The peak limiter threshold in dBFS.

  **Default:** service default

  Only used when peak limiting is enabled.

- `targetLkfs`: number — The target loudness in LKFS.

  **Default:** service default

  CALM Act recommends -24, EBU R-128 recommends -23.
