UGameplayStatics::SetGlobalPitchModulation

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallableBlueprintCosmetic

Description

Globally scales the pitch of all non-UI sounds, interpolating from the current value over TimeSec seconds. Useful for slow-motion audio effects that complement time dilation.

Caveats & Gotchas

• BlueprintCosmetic — this is client-side only and has no effect on a dedicated server.
• Applies to all non-UI sounds simultaneously; there is no per-sound-class pitch modulation through this API. For per-class control use Sound Classes.
• Setting TimeSec to 0 causes an immediate pitch snap, which can sound jarring. Use a short interpolation time even for 'instant' transitions.

Signature

static ENGINE_API void SetGlobalPitchModulation(const UObject* WorldContextObject, float PitchModulation, float TimeSec);

Parameters

Name	Type	Description	Default
WorldContextObject	const UObject*	Object used to retrieve the world context.	—
PitchModulation	float	Target global pitch scale. 1.0 = normal, < 1.0 = lower pitch, > 1.0 = higher pitch.	—
TimeSec	float	Duration in seconds to linearly interpolate from the current value to the target.	—

Return Type

void

Example

Pitch down sounds during slow-motion C++

// Pair with SetGlobalTimeDilation for slow-motion effect
UGameplayStatics::SetGlobalTimeDilation(this, 0.3f);
UGameplayStatics::SetGlobalPitchModulation(this, 0.5f, 0.1f);

// Restore
UGameplayStatics::SetGlobalTimeDilation(this, 1.0f);
UGameplayStatics::SetGlobalPitchModulation(this, 1.0f, 0.2f);
