# timescale

The identifier’s timescale is the number of uniquely identifiable timestamps in a second.

## Declaration

```swift
var timescale: Int
```

## Discussion

Discussion For example an audio file sampled at 44,100 Hz should have a timescale value of 44,100 (or an integer multiple of that) so that every sample has a unique timestamp.
