A method for performing a head-related transfer function (HRTF) convolution, when an audio signal is reproduced acoustically by an electro-acoustic conversion unit disposed in a nearby position of both ears of a listener. The method includes convoluting an HRTF into the audio signal, which allows the listener to listen to the audio signal such that a sound image is localized in a perceived virtual sound image localization position, measuring, when a sound source is disposed in the virtual sound image localization position, pre-collecting sound in the position of the electro-acoustic conversion unit, a direct-wave direction HRTF regarding the direction of a direct wave, and reflected-wave direction HRTFs regarding the directions of selected one or more reflected waves, from the sound source to the sound-collecting unit, and convoluting the obtained direct-wave direction HRTF, and the reflected-wave direction HRTFs into the audio signal. |
