# framePosition

The position in the file where the next read or write operation occurs.

## Declaration

```swift
var framePosition: AVAudioFramePosition { get set }
```

## Discussion

Discussion Set the framePosition property to perform a seek before a read or write. A read or write operation advances the frame position value by the number of frames it reads or writes.
