阅读说明：本技术 三维音频系统 (Three-dimensional audio system ) 是由 李齐 丁寅 J·奥兰 J·泰 于 2021-05-27 设计创作，主要内容包括：本说明包括可以在用户接口界面中呈现的三维空间的网格上定义滤波器及其分布网络的技术规范。可以从输入单声道或立体声中分离或从麦克风阵列的输出中确定多个音轨,其中每个音轨与在三维空间中相应声源位置有关。相对位置可由听者在用户界面设置。根据三维空间中听者和声源相对位置,在滤波器的分布网格中选择一对或多对滤波器。将每对滤波器应用于相应的音轨,以生成多个经滤波的音轨,然后用从多个经滤波的音轨生成三维声音供耳机收听。如使用多个扬声器,上述每个分离或确定的音轨可直接(即全通滤波)经放大器驱动每一个对应的扬声器。多个扬声器的声音可直接构成三维音场,不必佩戴耳机亦可听到所述的三维声音。(The specification includes a specification that may define a filter and its distribution network on a grid of a three-dimensional space presented in a user interface. Multiple audio tracks may be separated from the input mono or stereo or determined from the output of the microphone array, where each audio track is associated with a respective sound source location in three-dimensional space. The relative position may be set by the listener at the user interface. One or more pairs of filters are selected in the distribution grid of filters based on the relative positions of the listener and the sound source in three-dimensional space. Each pair of filters is applied to a respective audio track to generate a plurality of filtered audio tracks, and then three-dimensional sound is generated from the plurality of filtered audio tracks for listening by headphones. If multiple speakers are used, each of the separate or determined tracks may directly (i.e., all-pass filtered) drive each corresponding speaker through an amplifier. The sound of a plurality of loudspeakers can directly form a three-dimensional sound field, and the three-dimensional sound can be heard without wearing earphones.)
