# kAudioFilePropertyPacketTableInfo

Gets or sets an audio file packet table information structure for its supporting file types. When setting the structure, the sum of the values of the `mNumberValidFrames`, `mPrimingFrames` and `mRemainderFrames` fields must be the same as the total number of frames in all packets. If not, a `paramErr` is returned. To ensure this result, get the value of the property and make sure the sum of the three values you set has the same sum as the three values you got.

```
var kAudioFilePropertyPacketTableInfo: AudioFilePropertyID { get }
```
