# sharpness

The amount that the shape overlaps with bordering subbands.

```
var sharpness: Double { get set }
```

## Discussion

This property condenses the shape of the [`pattern`](/documentation/PHASE/PHASECardioidDirectivityModelSubbandParameters/pattern) such that higher values extend the shape frontwards. Increasing sharpness for dipole (a [`pattern`](/documentation/PHASE/PHASECardioidDirectivityModelSubbandParameters/pattern) value of `1.0`), extends the shape frontwards and backwards.

The default value is `1.0`. Values greater than `1.0` increase sharpness. The framework clamps the value to the range `[1.0,` <doc://com.apple.documentation/documentation/Swift/Double/greatestFiniteMagnitude>`]`.
