Summary:To provide an audio processing device and a program that bring more realistic content.SOLUTION: A distance attenuation characteristic generation unit generates a distance attenuation characteristic based on a distance from a reference point to a target position using a predetermined distance attenuation model, and a filter processing unit adds the distance attenuation characteristic to an input audio signal, the reference point is a position of a sound generation unit, which is the position of the sound generation unit, or a position displaced from the position of the sound generation unit by a predetermined correction amount in an object having the sound generation unit that emits sound.SELECTED DRAWING: Figure 1 【課題】より臨場感が高いコンテンツをもたらす音声処理装置、および、プログラムを提供する。【解決手段】距離減衰特性生成部は、所定の距離減衰モデルを用いて基準点から目標位置までの距離に基づく距離減衰特性を生成し、フィルタ処理部は、入力される音声信号に前記距離減衰特性を付加し、前記基準点は、音を放射する発音部を備える物体において、前記発音部の位置である発音部位置または前記発音部位置から所定の補正量で変位した位置である。【選択図】図１
