    • Various embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and audio and speaker systems. More specifically, disclosed are an apparatus and a method for processing signals for optimizing audio, such as 3D audio, by adjusting the filtering for cross-talk cancellation based on listener position and/or orientation. In one embodiment, an apparatus is configured to include a plurality of transducers, a memory, and a processor configured to execute instructions to determine a physical characteristic of a listener relative to the origination of the multiple channels of audio, to cancel crosstalk in a spatial region coincident with the listener at a first location, to detect a change in the physical characteristic of the listener, and to adjust the cancellation of crosstalk responsive to detecting the change in the physical characteristic to establish another spatial region at a second location.
    • 各种实施例一般涉及电气和电子硬件,计算机软件,有线和无线网络通信以及音频和扬声器系统。 更具体地,公开了一种通过基于收听者位置和/或取向调整用于串扰消除的过滤来处理用于优化音频的信号(诸如3D音频)的装置和方法。 在一个实施例中,设备被配置为包括多个换能器,存储器和被配置为执行指令以相对于多个音频通道的发起来确定收听者的物理特征的处理器,以消除空间中的串扰 与第一位置处的收听者重合,以检测收听者的物理特征的变化,以及响应于检测物理特征的变化来调整串扰的消除以在第二位置建立另一个空间区域。
