SOUND SIGNAL PROCESSING APPARATUS, SOUND SIGNAL PROCESSING METHOD, DISPLAY APPARATUS, RACK, PROGRAM, AND STORAGE MEDIUM

摘要

A sound signal processing apparatus (100) includes: an equalizer (110L) for enhancing an 8 kHz band of a sound signal (#1L); an equalizer (110R) for enhancing an 8 kHz band of a sound signal (#1R); and a filter (120) for delaying a phase of a sound signal (#2L). The filter (120) decreases correlation between the sound signals (#3L) and (#2R). This sufficiently moves a sound image upward, without use of a technique of pseudo surround.
