Abstract
During mixing of two musical tracks, the variations in combined output volume are reduced by analyzing either the intrinsic amplitude at which each track was mastered or the output amplitude (i.e. subsequent to amplification of the audio signal), and modifying either the intrinsic amplitude or amplification during the mixing phase. Musical clashes during mixing are avoided by analyzing intrinsic amplitudes of the two tracks at similar frequencies to detect the likelihood of a clash, and in the event a clash is detected, reducing the output amplitude of one of the tracks at the relevant frequency.
