Summary:To improve repeatability of direction feeling of sound while eliminating an individual difference.SOLUTION: An audio signal processing device includes a convolution part. The convolution part executes convolution processing using individual transfer functions from a sound source to each position of sound output units for a sound signal to each of the sound output units arranged at least longitudinally independently at the outside of ear auricles of a user.SELECTED DRAWING: Figure 7 【課題】容易に個人差を解消しつつ、音の方向感の再現性を向上させること。【解決手段】実施形態に係る音声信号処理装置は、畳み込み部を備える。畳み込み部は、ユーザの耳介の外側において少なくとも前後に独立して配置された音声出力ユニットそれぞれへ向けての音声信号に対し、音源から上記音声出力ユニットの各位置までの個別の伝達関数を用いた畳み込み処理を実行する。【選択図】図７
