UAudioComponent::SetPlaybackTimes
#include "Components/AudioComponent.h"
Access: public
Description
Sets the audio-thread playback time per sound wave, used to synchronize baked FFT or envelope-follower analysis data with actual playback position.
Caveats & Gotchas
- • Internal engine plumbing — only relevant when the component is using baked (cooked) FFT or envelope data, since that's the only consumer of these playback times.
- • Not Blueprint-exposed and not intended to be called from gameplay code; it's invoked by the audio engine as sounds progress.
