UAudioComponent::IsVirtualized

function Engine Blueprint Since unknown

#include "Components/AudioComponent.h"

Access: public Specifiers: constUFUNCTIONBlueprintCallable

Description

Returns whether the sound currently playing on this component has been virtualized rather than actually audible. Virtualization happens when the audio engine culls a low-priority sound to save voice channels while continuing to track its playback position.

Caveats & Gotchas

• A virtualized sound is still considered 'playing' by IsPlaying() — check IsVirtualized() separately if you need to distinguish audible playback from silent tracking.
• Virtualization behaviour depends on the platform's max channel count and the sound's concurrency/priority settings, so the same Play() call may or may not virtualize depending on runtime conditions.
• Returns false if nothing is currently playing on the component.

Example

Skip visual effects for virtualized sounds C++

{
    // Only trigger visualizer/VFX when the sound is actually audible
    PlayAudioReactiveEffect();
}
