    • A method and apparatus is provided for presenting a user with a visual indication of the likely user-perceived location of sound sources in an audio field generated from left and right audio channel signals. To produce this visual indication, corresponding components in the left and right channel signals are detected by a correlation arrangement. These corresponding components are then used by a source-determination arrangement to infer the presence of at least one sound source and to determine the azimuth location of this source within the audio field. A display processing arrangement causes a visual indication of the sound source and its location to be presented to the user.
    • 提供了一种方法和装置,用于向用户呈现在从左和右声道信号信号产生的音频场中可能的用户感知的声源位置的视觉指示。 为了产生该视觉指示,通过相关布置来检测左右声道信号中的相应组件。 然后,源确定装置使用这些对应的部件来推断出至少一个声源的存在并且确定该源在音频场内的方位位置。 显示处理装置使得声源及其位置的视觉指示被呈现给用户。
