# AVAudio3DMixingSourceMode.spatializeIfMono

A mono input bus that renders as a point source at the location of the source node.

## Declaration

```swift
case spatializeIfMono
```

## Discussion

Discussion The system bypasses an input bus with more than one channel. This is equivalent to AVAudio3DMixingSourceMode.pointSource for a mono bus and AVAudio3DMixingSourceMode.bypass for a bus with more than one channel.
