# Sandbox.SoundHandle.Loopback

```csharp
bool Loopback { get; set; }
```

If true, then this sound won't be played unless voice_loopback is 1. The assumption is that it's the 
local user's voice. Amplitude and visme data will still be available!

Declared in [Sandbox.SoundHandle](/api/Sandbox.SoundHandle).
Assembly: `Sandbox.Engine`.
