We tested twenty individuals for our study. Each individual listened to three music clips. The right speaker played a volume adjusted remastered recording while the left side played a volume adjusted original track. Each participant was asked to rate the sound quality for each side of each recording on a scale of 1 to 10 based on preference and sound quality adding any adjectives to describe the differences between them as needed.Furthermore, since some of the clipping in the tracks occurs at very high sound frequencies, a hearing range test was also given. To compensate for individual sound quality scale differences, the differences between the two sides was also averaged, not just the average rating of each side’s sound clip.
