I want to move the character mouth using sound. I already did this to my playable character using the Audio Capture component > On Audio Envelope Value (and at this point I can get the envelope value).
Now I want to do this to my NPCs, but instead of the microphone (Audio Capture), I want to use recorded sounds.
On UE4 4.23 there is the Audio Curve Source component inside the NPCs blueprint. Inside the audio I will use, I checked “Enable Amplitude Envelope Analysis”.
I try to “Get Cooked Envelope Data” and the return value is false.
I also tried to just spawn a 2d sound, and also can’t “Get Cooked Envelope Data”.
Why can’t I get the envelope of a sound (whatever if it’s an Audio Curve Source component or an spawned 2d sound) like I do on Audio Capture component?
