摘要： A signal processing method and system are provided for delivering spatialized sound using highly optimized inverse filters to deliver narrow localized beams of sound from the included speaker array. The inventive method can be used to provide private listening areas in a public space and provide spatialization of source material for individual users to create a virtual 3D audio effect. In a binaural mode, a speaker array provides two targeted beams aimed towards the primary user's ears—one discrete beam for the left ear and one discrete beam for the right ear.

摘要： A system and method for producing a binaural and localized audio signal to a user is provided. A signal processing method is provided for delivering spatialized sound in various ways using highly optimized inverse filters to deliver narrow localized beams of sound from the included speaker array. The inventive method can be used to provide private listening areas in a public space and provide spatialization of source material for a single user to create a virtual surround sound effect. In a binaural mode, a speaker array provides two targeted beams aimed towards the primary user's ears—one discrete beam for the left ear and one discrete beam for the right ear. In a privacy mode, a privacy zone could be created in which a primary audio beam would deliver a signal of interest to the user while secondary beams would be aimed at different angles to provide a masking noise.
摘要翻译：提供了一种用于向用户产生双耳和局部音频信号的系统和方法。提供了一种信号处理方法，用于使用高度优化的反向滤波器以各种方式传送空间化声音，以从所包括的扬声器阵列传送窄的局部声束。本发明的方法可以用于在公共空间中提供私人收听区域，并且为单个用户提供源材料的空间化以创建虚拟环绕声效果。在双耳模式中，扬声器阵列提供了朝向主用户的耳朵的两个目标波束 - 用于左耳的一个离散波束和用于右耳的一个离散波束。在隐私模式中，可以创建隐私区域，其中主音频波束将向用户传递感兴趣的信号，而辅助波束将针对不同的角度以提供掩蔽噪声。
