UAudioComponent::EnvelopeFollowerAttackTime
#include "Components/AudioComponent.h"
Access: public
Specifiers: UPROPERTYEditAnywhereBlueprintReadWrite
Description
The attack time, in milliseconds, for the envelope follower used to compute amplitude values delegates like OnAudioSingleEnvelopeValue can read.
Caveats & Gotchas
- • Only affects the audio-mixer envelope follower — this has no effect when the legacy (non-audio-mixer) audio engine is in use.
- • A shorter attack time makes the reported envelope react faster to sudden volume increases, but can introduce more jitter in a value used to drive visuals like a VU meter.
