Understanding Match Volume statistics
Loudness
Is the average amplitude value.
Perceived
Is the average amplitude value adjusted for the human ear’s greater sensitivity to midrange frequencies.
Total RMS
Is the most common root-mean-square amplitude across the entire file. For example, if the majority of two
files is -50 dBFS, the total RMS values would reflect that, even if one file contains more loud passages.
RMS amplitude often better reflects perceived amplitude than the absolute Loudness average.
Peak
Is the maximum amplitude.
% Clip
Is the percentage of the waveform that would be clipped as a result of normalization. Clipping won’t occur if
limiting is used. However, clipping should ideally be avoided prior to limiting. If any matched files show more than
0% clipping, click Undo, and match to a slightly lower amplitude.
