下面对本申请实施例进行详细介绍。
请参阅图1B，图1B是本申请实施例公开的一种3D音效处理方法的流程示意图，应用于上述图1A所描述的电子设备，该3D音效处理方法包括如下步骤101-103。
101、获取声源的第一三维坐标，以及所述声源产生的单声道数据。
其中，本申请实施例可应用于虚拟现实/增强现实场景，或者，3D录音场景。本申请实施例中，声源可以为虚拟场景中一发声体，例如，游戏场景中的一个飞机，声源可以为固定声源，或者，移动声源。由于虚拟场景中每一物体均可以对应一个三维坐标，因此，可以获取声源的第一三维坐标，在声源发出声音时，则可以获取生源产生的单声道数据。
102、获取目标对象的第二三维坐标，所述第一三维坐标、所述第二三维坐标基于同一坐标原点。
其中，目标对象也可以对应一个三维坐标，即第二三维坐标，当然，第一三维坐标与第二三维坐标为不同的位置，且第一三维坐标、第二三维坐标基于同一坐标原点。
可选地，在所述目标对象处于游戏场景时，上述步骤102，获取目标对象的第二三维坐标，可包括如下步骤：
21、获取所述游戏场景对应的地图；
22、在所述地图中确定所述目标对象对应的坐标位置，得到所述第二三维坐标。
其中，在目标对象处于游戏场景时，目标对象可视为游戏中一角色，当然，具体实现中，游戏场景可对应一三维地图，因此，电子设备可以获取游戏场景对应的地图，并在地图中确定目标对象对应的坐标位置，得到第二三维坐标，如此，针对不同的游戏，可实时知晓角色位置，在本申请实施例中，针对角色具体位置，能够生成3D音效，让用户在游戏时，能够身临其境，感觉游戏世界更为逼真。
103、依据所述第一三维坐标、所述第二三维坐标以及所述单声道数据生成目标双声道数据。
其中，在知晓声源的第一坐标位置、目标对象的第二三维坐标，则可以将单声道数据生成双声道数据，具体地，可以将第一三维坐标、第二三维坐标、单声道数据输入到HRTF模型中，得到双声道数据。
举例说明下，具体实现中，电子设备可根据发声体的空间三维坐标位置(x，y，z)，该位置可以是任意坐标，再根据发声体产生的单声道数据，生成左右声道，左右声道的产生原理是依据发声体距离听者(X，Y，Z)，单点数据传输左耳和传输到右耳数据的时间差以及相位压力差生成双声道声音。当然，上述根据发声体的空间三维坐标位置(x，y，z)，该位置可以是任意坐标；另外，上述根据发声体产生的单声道数据，生成左右声道，例如， 根据发声体的空间三维坐标位置(x，y，z)，固定听者位置为(0，0，0)之间不管听者如何移动，发声体的位置双声道声音。
可选地，上述步骤103，依据所述第一三维坐标、所述第二三维坐标以及所述单声道数据生成目标双声道数据，可包括如下步骤：
31、将所述单声道数据生成所述第一三维坐标与所述第二三维坐标之间的多路双声道数据，每路双声道数据对应唯一传播方向；
32、将所述多路双声道数据合成目标双声道数据。
其中，声源的原始声音数据为单声道数据，通过算法处理(例如，HRTF算法)，则可以得到双声道数据，由于在现实环境中，声音是沿着各个方向进行传播，当然，在传播过程中，也会出现反射、折射、干涉、衍射等现象，因此，本申请实施例中，用于最终合成目标双声道数据的仅仅为经过第一三维坐标与第二三维坐标之间的多路双声道数据，将该多路双声道数据合成目标双声道数据。
可选地，上述步骤32，将所述多路双声道数据合成目标双声道数据，可包括如下步骤：
321、以所述第一三维坐标与所述第二三维坐标为轴线作横截面，将所述多路双声道数据进行划分，得到第一双声道数据集合和第二双声道数据集合，所述第一双声道数据集合、所述第二声道数据集合均包括至少一路双声道数据；
322、将所述第一双声道数据集合进行合成，得到第一单声道数据；
323、将所述第二双声道数据集合进行合成，得到第二单声道数据；
324、将所述第一单声道数据、所述第二单声道数据进行合成，得到所述目标双声道数据。
其中，在知晓第一三维坐标，第二三维坐标之后，可以第一三维坐标与第二三维坐标为轴线作横截面，由于声音传播方向一定，传播轨迹也会沿着一定的对称轴具备一定的对称性，如图1C所示，第一三维坐标与第二三维坐标形成轴线，以该轴线作横截面，可以将多路双声道数据进行划分，得到第一双声道数据集合和第二双声道数据集合，不考虑外在因素，例如，折射，反射，衍射等情况，则第一双声道数据集合与第二双声道数据集合也可以是包含相同路数的双声道数据，且不同集合的双声道数据也是对称关系，第一双声道数据集合、第二声道数据集合均包括至少一路双声道数据，具体实现中，电子设备可将第一双声道数据集合进行合成，得到第一单声道数据，电子设备可以包括左右耳机，第一单声道数据可以主要由左耳机播放，相应地，电子设备可将第二双声道数据集合进行合成，得到第二单声道数据，第二单声道数据可以主要由右耳机播放，最后，将第一单声道数据、第二单声道数据进行合成，得到目标双声道数据。
可选地，上述步骤322，将所述第一双声道数据集合进行合成，得到第一单声道数据，可包括如下步骤：
3221、将所述第一双声道数据集合中每一路双声道数据的能量值，得到多个能量值；
3222、从所述多个能量值中选取大于第一能量阈值的能量值，得到多个第一目标能量值；
3223、确定所述多个第一目标能量值对应的第一双声道数据，将所述第一双声道数据进行合成，得到所述第一单声道数据。
其中，上述第一能量阈值可以由用户自行设置或者系统默认。具体实现中，电子设备可将第一双声道数据集合中每一路双声道数据的能量值，得到多个能量值，进而，从多个能量值中选取大于第一能量阈值的能量值，得到多个第一目标能量值，确定多个第一目标能量值对应的第一双声道数据，将第一双声道数据进行合成，得到第一单声道数据。
可选地，基于与上述步骤3221-步骤3223，也可以实现上述步骤323，在此不再赘述。
可选地，在上述步骤101-步骤103之间，还可以包括如下步骤：
A1、获取所述目标对象的面部朝向；
则，上述步骤103，依据所述第一三维坐标、所述第二三维坐标以及所述单声道数据生成目标双声道数据，可按照如下方式实施：
依据所述面部朝向、所述第一三维坐标、所述第二三维坐标以及所述单声道数据生成目标双声道数据。
其中，具体实现中，用户不同的面部朝向，则听到的3D音效也不一样，鉴于此，本申请实施例中，则考虑目标对象的面部朝向，电子设备可检测目标对象的面部朝向，具体地，若是游戏场景，则可以检测目标对象的相对于声源的朝向作为目标对象的面部朝向，若电子设备为是考虑用户头戴设备，例如，头戴式虚拟现实眼镜、虚拟现实头盔、虚拟现实头带显示设备等。人头方向的检测可以使用多种传感器，包括但不限于电阻式传感器、力学传感器、光敏传感器、超声波传感器、肌肉传感器等，在此不做限定。可以是其中一种传感器，也可以是其中几种传感器的组合，可以是一个传感器还可以是几个传感器的组合。人头方向的检测可以按照每隔预设时间间隔进行检测，预设时间间隔可以由用户自行设置或者系统默认。
可选地，在上述步骤103之后，还可以包括如下步骤：
B1、获取当前环境对应的目标壁纸；
B2、按照预设的壁纸与混响效果参数之间的映射关系，确定所述目标壁纸对应的目标混响效果参数；
B3、依据所述目标混响效果参数对所述目标双声道数据进行处理，得到混响双声道数据。
其中，上述混响效果参数可以包括以下至少一种：输入电平、低频切点、高频切点、早反射时间、扩散程度、低混比率、残响时间、高频衰点、分频点、原始干声音量、早反射声音量、混响音量、声场宽度、输出声场、尾音等等，在此不作限定。壁纸可以理解为环境的背景，此处环境可以为真实物理环境或者游戏环境，不同的环境可以对应不同的壁纸，在游戏场景下，可以确定目标对象的位置，进而，依据地图确定该位置对应的目标壁纸，若非游戏场景下，则可以通过环境传感器检测当前环境参数，依据当前环境参数确定当前环境，其中，环境传感器可以为以下至少一种传感器、湿度传感器、温度传感器、超声波传感器、距离传感器、摄像头等等，在此不做限定，上述环境参数可以为以下至少一种：温度、湿度、距离、影像等等，在此不做限定，电子设备中可以预先存储环境参数与环境之间的映射关系，进而，依据该映射关系确定当前环境参数对应的当前环境，电子设备中还可以预先存储环境与壁纸之间的映射关系，进而，依据该映射关系确定当前环境对应的目标壁纸，电子设备中还预先存储预设的壁纸与混响效果参数之间的映射关系，依据 该映射关系可以确定目标壁纸对应的目标混响效果参数(reverb)，进而，依据目标混响效果参数对目标双声道数据进行处理，得到混响双声道数据，具体地，可以将目标混响效果参数对应的参数输入到HRTF算法模型中，得到混响双声道数据。
可以看出，本申请实施例中所描述的3D音效处理方法，获取声源的第一三维坐标，以及声源产生的单声道数据，获取目标对象的第二三维坐标，第一三维坐标、第二三维坐标基于同一坐标原点，依据第一三维坐标、第二三维坐标以及单声道数据生成目标双声道数据，如此，在确定了声源的第一三维坐标以及目标对象的第二三维坐标，则可以生成3D音效，提升了用户体验。
