Unity : Audio buffer being cleared.

Question

Before integrating, I obtained the audio buffer from the AudioSource component and generated a waveform texture from the AudioClip, but after integrating WWise, I found out that when I start the project, the audio buffer has been completely zero-cleared. From other forum posts, I know that the audio buffer is not exposed to Unity, but is there anyway to prevent the audio buffer being cleared, or maybe retrieving the data before it is cleared?
