# overlapFactor

The amount of overlap between successive analysis windows when the model operates on a fixed-size audio block.

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

## Discussion

The property defaults to `0.5` (50%) and supports values in the range `[0.0, 1.0]`.

Sound analyses that use a fixed-size audio block typically benefit with an overlap factor that’s greater than zero. An overlap factor of `0.0` may negatively affect your sound classifier’s accuracy because a sound may span two analysis windows. However, an overlap factor of `0.5` ensures each sound aligns near the center of at least one analysis window.

> Important:
> Higher overlap factors increase computational complexity, especially for values greater than `0.5`.
