Hidden Message
When the track is played backwards, a hidden message can be heard. At normal speed it is inaudible, but sounds similar to the Gravemind's voice. However, when sped up words can be heard and the voice begin's to sound like that of a prophet. It is more likely that it is 032 Mendicant Bias because Gravemind or the prophets wouldn't be seeking for forgiveness. Whether either is the owner of the mysterious voice, or something/someone else is debatable.
