AUDIO SIGNAL PROCESSING DEVICE, AUDIO SIGNAL PROCESSING METHOD, DISPLAY DEVICE, RACK, PROGRAM, AND RECORDING MEDIUM

摘要

An audio signal processing device includes: an equalizer (110L) which emphasizes an 8-kHz band in an audio signal (#1L); an equalizer (110R) which emphasizes an 8-kHz band in an audio signal (#1R); and a filter (120) which delays the phase of the audio signal (#2L). The filter (120) lowers the correlation between an audio signal (#3L) and an audio signal (#2R). This enables sufficient increase of the sound image without using the pseudo-surround technique.
