Results
This part of the homework was fairly straightforward. I chose to use two different sampling rates so that it could be listened to at different speeds.
It took me a long time to decipher what was actually being said in the song. But, it turns out that the singer says, "Beyond the realms of death" (when played forward). When the song is played in reverse, it sounds like he's saying, "I took my own life".
