# AudioOnlyHlsSettingsProps

Properties for audio-only HLS settings.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/m3u8-settings.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/m3u8-settings.ts#L306)

## Example

```ts
declare const bucket: s3.IBucket;
declare const video: medialive.EncodeConfiguration;
declare const audio: medialive.EncodeConfiguration;

medialive.OutputGroupConfiguration.hls({
  name: 'hls',
  destinations: [medialive.OutputDestination.toBucket(bucket, 'live/stream')],
  outputs: [
    {
      encodes: [video],
      outputName: 'video',
      hlsSettings: medialive.HlsSettings.standard({
        m3u8Settings: medialive.M3u8Settings.of({
          scte35Behavior: medialive.M3u8Scte35Behavior.PASSTHROUGH,
          programNum: 1,
        }),
      }),
    },
    {
      encodes: [audio],
      outputName: 'audio',
      hlsSettings: medialive.HlsSettings.audioOnly({
        audioGroupId: 'program',
        audioOnlyImage: medialive.FileLocation.fromBucket(bucket, 'art/cover.png'),
      }),

## Properties

- `audioGroupId`: string — The group that this audio rendition belongs to.

  **Default:** service default

Provide a `FileLocation` referencing an S3 bucket (`FileLocation.fromBucket`, which auto-grants read access) or a URL (`FileLocation.url`).

  **Default:** no cover art

- `audioTrackType`: [HlsAudioTrackType](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.HlsAudioTrackType.html) — How the audio rendition is signaled in the HLS manifest.

  **Default:** service default

- `segmentType`: [HlsAudioOnlySegmentType](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.HlsAudioOnlySegmentType.html) — The segment container type.
