## Example

```ts
// AAC stereo
const aac = medialive.EncodeConfiguration.audio({
  name: 'aac_stereo',
  codec: medialive.AudioCodecSettings.aac({
    bitrate: Bitrate.kbps(192),
    codingMode: medialive.AacCodingMode.CODING_MODE_2_0,
  }),
});

// AC3 5.1
const ac3 = medialive.EncodeConfiguration.audio({
  name: 'ac3_surround',
  codec: medialive.AudioCodecSettings.ac3({
    bitrate: Bitrate.kbps(384),
    codingMode: medialive.Ac3CodingMode.CODING_MODE_3_2_LFE,
  }),
});
```
