Our project aims to examine the dynamic range of different recorded music and how trends in mastering have effected it over time. We will analyze specific songs from different time periods as well as personal preferences of test subjects as to which type of mastering they find preferable. Because of the volume difference between different mastering styles, we will adjust the average decibel output to be equal for each sample. Based on the results of our research, we will attempt to remaster a song ourselves in the style that has the highest approval of our test subjects.
