Hello everyone  
I would like to ask a question about the Audio . In Unity, the AudioSource component has a public method called GetOutputData(), which can get the output data block during playback, but I have not found similar methods and variables in UE4. In addition, I also saw the USoundWave class. There are no new discoveries. Recently, there is a need to obtain the data during this playback, and then calculate the phoneme value for lip synchronization. I am using OVRLipsync, which is preprocessed as a sequence file in Oculus Demo project, but I need to generate sound in real time. Synchronization, so with this requirement, please help me and give pointers on which direction to solve this problem. thank you very much
