# AVAudio3DMixingPointSourceInHeadMode

The in-head modes for a point source.

```
enum AVAudio3DMixingPointSourceInHeadMode
```

## Overview

The in-head mode that determines what happens when a [`AVAudio3DMixingSourceMode.pointSource`](/documentation/AVFAudio/AVAudio3DMixingSourceMode/pointSource) moves inside the head of the listener. The in-head mode applies when using the [`AVAudio3DMixingRenderingAlgorithm.auto`](/documentation/AVFAudio/AVAudio3DMixingRenderingAlgorithm/auto) rendering algorithm.

## Topics

### In-Head Modes

[`AVAudio3DMixingPointSourceInHeadModeMono`](/documentation/AVFAudio/AVAudio3DMixingPointSourceInHeadMode/mono)

The point source remains a single mono source inside the head of the listener regardless of the channels it consists of.

[`AVAudio3DMixingPointSourceInHeadModeBypass`](/documentation/AVFAudio/AVAudio3DMixingPointSourceInHeadMode/bypass)

The point source distributes into each output channel inside the head of the listener.
