# AVAudio3DMixingSourceMode.ambienceBed

The input channels spread around the listener as far-field sources that anchor to global space.

## Declaration

```swift
case ambienceBed
```

## Discussion

Discussion The rendering depends on listener orientation, but not on listener position. The audio channel layout of the bus specifies the directions of the input channels. The direction of the source node controls the rotation of the bed in the global space.
