# isShutterSoundSuppressionEnabled

A Boolean value that indicates whether to suppress the built-in shutter sound when capturing a photo.

```
var isShutterSoundSuppressionEnabled: Bool { get set }
```

## Discussion

The default value is <doc://com.apple.documentation/documentation/Swift/false>. Set the value to <doc://com.apple.documentation/documentation/Swift/true> to suppress the photo output’s built-in shutter sound for this request. The photo output throws an invalid argument exception when calling [`capturePhoto(with:delegate:)`](/documentation/AVFoundation/AVCapturePhotoOutput/capturePhoto(with:delegate:)) if its [`isShutterSoundSuppressionSupported`](/documentation/AVFoundation/AVCapturePhotoOutput/isShutterSoundSuppressionSupported) property returns <doc://com.apple.documentation/documentation/Swift/false>.
