# AudioPidConfig

Configuration for a single audio PID in a PID-based selector.

- 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#L84)

## 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 audioPreMixerSettings: medialive_alpha.AudioPreMixerSettings;
declare const dolbyEProgramSelection: medialive_alpha.DolbyEProgramSelection;
const audioPidConfig: medialive_alpha.AudioPidConfig = {
  pid: 123,

  // the properties below are optional
  dolbyEDecode: dolbyEProgramSelection,
  premixSettings: audioPreMixerSettings,
};
```

## Properties

- `dolbyEDecode`: [DolbyEProgramSelection](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.DolbyEProgramSelection.html) — Which Dolby E program to decode from this PID.

  **Default:** no Dolby E decoding

- `pid`: number (required) — The packet identifier (PID) value from within the source.

- `premixSettings`: [AudioPreMixerSettings](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.AudioPreMixerSettings.html) — Pre-mixer settings for this PID (gain, channel remix, loudness normalization).
