# captureAudioDataOutput

An audio data output that routes and converts captured audio buffers to async sequences.

## Declaration

```swift
final var captureAudioDataOutput: AVCaptureAudioDataOutput { get }
```

## Discussion

Discussion Add this output to an existing capture session. Calling providerWithSession(from:compatibleWith:priority:) automatically adds this output to the session it creates. Do not modify the output’s sample buffer delegate or callback queue.
