Abstract:
There is provided an auditory sense correction device capable of adding favorable loudness characteristics to an output sound without depending on sound source characteristics of an audio signal even when a high-frequency band or a low-frequency band of the audio signal has already been subjected to loudness correction. The auditory sense correction device 1 includes: a loudness processing section 2 which applies loudness processing to audio signals on a frequency band basis, a gain calculation section 4 which calculates a level difference between a signal level of each frequency band and signal level of original frequency band; and gain setting section 5 which applies a correction gain of each frequency band to the audio signal of each frequency band that has been subjected to loudness processing.
