# AudioPreMixerSettings

Audio pre-mixer settings for normalizing audio before interleaving.

Applied per-PID or per-track before tracks are combined.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/audio-selector.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/audio-selector.ts#L116)

## 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 audioPreMixerSettings = medialive_alpha.AudioPreMixerSettings.of({
  audioNormalizationSettings: {
    algorithm: audioNormalizationAlgorithm,
    algorithmControl: audioNormalizationAlgorithmControl,
    peakCalculation: audioNormalizationPeakCalculation,
    peakLimiterThreshold: 123,
    targetLkfs: 123,
  },
  channels: 123,
  gainDb: 123,
  remixSettings: {
    channelMappings: [{
      inputChannelLevels: [{
        inputChannel: 123,

        // the properties below are optional
        gain: 123,
      }],
      outputChannel: 123,
    }],

    // the properties below are optional
    channelsIn: 123,
    channelsOut: 123,
  },
});
```
