UAudioComponent::SetPitchMultiplier

function Engine Blueprint Since unknown

#include "Components/AudioComponent.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Sets the component's PitchMultiplier property, applied instantly. A value of 1.0 is unmodified pitch; higher values raise pitch and speed up playback, lower values do the reverse.

Caveats & Gotchas

• Pitch shifting on most sound sources also changes playback speed since it's implemented as resampling, not a pure pitch-shift effect.
• Extreme values (near 0 or very large) can produce audible artifacts or effectively silence/distort the sound depending on the platform's audio engine.
• Takes effect immediately with no interpolation, unlike AdjustVolume().
