"
Loudness war" or "
loudness race" is the popular name given to the trend of increasing audio levels in recorded music since the early 1990s, which many critics believe reduces sound quality and listener enjoyment. Increasing
loudness was first reported as early as the 1940s with respect to mastering practices for
7" singles. The maximum
peak level of analog recordings such as these is limited by varying specifications of electronic equipment along the chain from source to listener, including
vinyl record and
cassette players.
