虚拟现实VR音频的处理方法及相应设备
摘要：
本发明提供了一种虚拟现实VR音频处理的方法及相应设备，包括VR音频的发送端获取高保真立体声Ambisonics信号旋转角度，其中，Ambisonics信号旋转角度是根据VR音频的接收端对应的第一设备旋转角度确定出的，然后根据获取的Ambisonics信号旋转角度，对Ambisonics信号进行旋转，和/或，VR音频的发送端获取根据VR音频的相关信息确定的混合阶高保真立体声MOA信号的阶数，然后依据MOA信号的阶数，从高保真立体声Ambisonics信号中提取出MOA信号。本发明实施例适用于根据设备的旋转角度确定Ambisonics信号旋转角度，进行旋转，并提取出MOA信号。
摘要（英）：

The invention provides a virtual reality (VR) audio processing method and corresponding equipment. The method comprises steps: a transmitting terminal of a VR audio acquires a hi-fi stereo Ambisonicssignal rotation angle, wherein the Ambisonics signal rotation angle is determined according to a first equipment rotation angle corresponding to a receiving terminal of the VR audio; an Ambisonics signal is rotated according to the acquired Ambisonics signal rotation angle, and/or, the transmitting terminal of the VR audio acquires the order of a mixed order hi-fi stereo MOA signal determined according to related information of the VR audio; and according to the order of the MOA signal, an MOA signal is extracted from the hi-fi stereo Ambisonics signal. Accordingly, an Ambisonics signal rotation angle according to a rotation angle of the equipment is determined, the rotation occurs, and an MOA signal is extracted.
