LOUDNESS LEVEL METER FOR POST-PRODUCTION AND CALCULATION PROGRAM FOR LOUDNESS LEVEL FOR USE IN POST-PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a loudness level meter for post-production capable of displaying a control amount of a fader in dB value for keeping a loudness level at a constant value.;SOLUTION: The loudness level meter for post-production includes a level-adjusted sound signal generation part 1m for adjusting an input sound signal level for generating a level-adjusted sound signal, an input sound signal loudness level calculation part 20 for calculating the loudness level of the input sound signal, a level-adjusted sound signal loudness level calculation part 2m for calculating the loudness level of the level-adjusted sound signal, a function determination part 3 for determining a function whose independent variable values are the input sound signal loudness level and the level-adjusted sound signal loudness level and whose dependent variable values are an input level and an adjusted level, and a level correction value calculation part 4 for calculating a difference between a target level and an input level which is the dependent variable value when a target loudness level is the independent variable value of the function as a level correction value.;COPYRIGHT: (C)2007,JPO&INPIT
