The term "loudness war" refers to the ongoing increase in loudness of recorded music over the last 30 years or so. The problem is not the playback level, which is controlled by the end user; rather, the problem relates to the use of dynamic range compression to make songs seem louder than others with the same peak level. As a result, most commercially distributed music now has very little dynamic range. Hypercompressed music may also cause listening fatigue. More information about the loudness war is available in a video presentation, "The Loudness War: Background, Speculation and Recommendations," and the accompanying Audio Engineering Society paper, http:///docs/loudnesswar .
