# PHASESpatialCategory

Sound resonance effects for spatial mixing.

```
struct PHASESpatialCategory
```

## Discussion

This class identifies the various audio layers that a spatial mixer offers as keys to the [`entries`](/documentation/PHASE/PHASESpatialPipeline/entries) dictionary.

## Topics

### Creating a Spatial Category

[`init(rawValue: String)`](/documentation/PHASE/PHASESpatialCategory/init(rawValue:))

Initializes a spatial category with the given string.

### Categories

[`static let directPathTransmission: PHASESpatialCategory`](/documentation/PHASE/PHASESpatialCategory/directPathTransmission)

A spatial category that refers to the unfiltered audio signal.

[`static let earlyReflections: PHASESpatialCategory`](/documentation/PHASE/PHASESpatialCategory/earlyReflections)

A spatial category that refers to the earlier echoes along the duration of sound resonance.

[`static let lateReverb: PHASESpatialCategory`](/documentation/PHASE/PHASESpatialCategory/lateReverb)

A spatial category that refers to the later echoes along the duration of sound resonance.
