The document discusses editing an original sound file by using PitchAdjust and PlaybackRate boxes to create 3 edited versions. The first version increased the PlaybackRate to 1.5, making the audio play faster. The second version kept the same PlaybackRate but changed the PitchAdjust to -10, making the sound deeper. The third version kept the PitchAdjust the same but reduced the PlaybackRate to 0.5, making the audio play much slower.
