Zusammenfassung:PROBLEM TO BE SOLVED: To provide an effect application device capable of solving the problem that a sound is localized in the head or the problem that tones may be changed in accordance with types of headphones, when a headphone is used.SOLUTION: A DSP 10 performs equalizer processing for speaker adjustment that processes all bands with seven bands but if a headphone 320 is selected by output selection means, the DSP 10 performs equalizer processing for headphone adjustment over all the bands with three bands in the equalizer processing and performs processing while replacing processing of the other bands with in-head localization sense mitigation processing for the headphone 320. Since the headphone 320 and a speaker 318 are used in an exclusive manner, by using the same program storage region, in-head localization sense can be reduced or tones can be adjusted efficiently while using the headphone 320.SELECTED DRAWING: Figure 3 【課題】 ヘッドホン使用時に頭内に音が定位する問題や、ヘッドホンの種類によって音色が変わる問題を解決できる効果付与装置を提供する。【解決手段】 DSP10は7バンドで全帯域を処理するスピーカ調整用イコライザ処理を行うが、出力選択手段によりヘッドホン320が選択された場合には、DSP10はイコライザ処理のうち3バンドで全帯域のヘッドホン調整用イコライザ処理を行うと共に、他のバンドの処理をヘッドホン320用に頭内定位感緩和処理に置き換えて処理することになり、ヘッドホン320とスピーカ318は排他的に使用されるため、同一のプログラム記憶領域を使用することで、効率良くヘッドホン320使用時の頭内定位感の軽減や音色の調整が可能になる。【選択図】 図3
