# Sandbox.SoundFile.Visemes

```csharp
VisemeTrack Visemes { get; set; }
```

The lipsync track for this sound, or null if it doesn't have one. Authored
in the sound editor's viseme timeline. Read from the compiled file when the
sound resource loads - check [Sandbox.SoundFile.IsValidForPlayback](/api/Sandbox.SoundFile/IsValidForPlayback) to tell
"no track" apart from "not loaded yet".

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