IT之家 12 月 25 日消息，华为常务董事、产品投资评审委员会主任、终端 BG 董事长余承东今日发布视频，详细介绍了耳机空间音频的技术原理，并透露只 需要在两只耳机中模拟不同的波形变化，就可以让声音出现在任何位置。 据余承东介绍，人的耳廓就是声音重要的方向定位器之一，不同方向的声音撞击到耳廓后会产生波形的变化，人耳捕捉到这个变化就能定位声音的位置。华 为声学实验室采集了上千组人耳相关数据，还研发出了空间声场还原算法。 IT之家从华为官网获悉，华为 FreeBuds Pro 5 / 4 / 3 / 2 系列、FreeClip 1 / 2、FreeBuds 7i、FreeBuds 6、FreeBuds 5 等耳机支持 Audio Vivid 三维声标准，采用 华为自研的场景化空间音频声场渲染引擎，可提供有声剧场、电影院、音乐厅三种空间音频音效模式。 另外，华为 FreeArc / FreeBuds 6i 耳机支持空间音效。据介绍，空间音效和空间音频均采用华为自研渲染引擎，经过声学定位技术渲染和空间渲染提升空间 感；均会针对当前耳机，单独调教声学参数，但空间音效不支持头部跟踪效果和切换空间场景。 IT之家 12 ...
