音频监听器 (Audio Listener) 充当类似于麦克风的设备。它接收来自场景中任何给定音频源的输入,并通过计算机扬声器播放声音。对于大多数应用程序,最有意义的是将监听器附加到主摄像机。如果音频监听器位于混响区的边界内,则会将混响应用于场景中的所有可闻声音。此外,音频效果可应用于监听器,并将应用于场景中的所有可闻声音。
音频监听器没有属性。但必须添加音频监听器才能工作。默认情况下,音频监听器将被添加到主摄像机。
音频监听器与音频源配合使用,可让您为游戏营造听觉体验。当音频监听器连接到场景中的__游戏对象__时,任何足够接近监听器的源都将被拾取并输出到计算机的扬声器。每个场景只能有 1 个音频监听器才能正常工作。
如果音频源是 3D(请参阅音频剪辑中的导入设置),监听器将模拟 3D 世界中声音的位置、速度和方向(您可以在音频源中非常详细地调整衰减和 3D/2D 行为)。2D 将忽略任何 3D 处理。例如,如果角色走出街道进入夜总会,那么夜总会的音乐可能应该是 2D,而俱乐部中人物的个人声音应该是单声道的,其真实的定位由 Unity 处理。
您应该将音频监听器连接到主摄像机或代表玩家的游戏对象。请尝试以上两种方法,找到最适合您游戏的方法。
