Abstract
A sound processing device includes an equalizer that tunes the frequency characteristic so that a frequency characteristic of the sound wave listened in a second environment replicates the frequency characteristic of a sound wave listened in a first environment. A plurality of the equalizers is provided corresponding to a plurality of sound image signals that has respective sound images to be localized in different directions. In addition, the equalizer performs a unique frequency characteristic changing process to the corresponding sound image signal. Each equalizer has a transfer function that cancels the unique change to the frequency characteristic caused in accordance with the sound localization direction of the sound image signal.
