扬声器

扬声器对象。

The speaker object is used to give sound in the 3D Viewport. After adding the object, the various settings can be changed in the Properties.

选项

声音

打开

用于加载音频文件的 数据块菜单 。加载声音时可以检查两个属性：

• 缓存

  这意味着整个声音将被解码，原始音频数据将被缓冲在内存中，从而加快播放速度，但会占用大量内存。因此，这应该用于更频繁播放的短音效，但不适用于音乐等较长的音频文件。

  单声道

  对于任何3D音频或平移效果，声源必须是单声道，否则假设3D音频和声像信息已经存在于多声道文件中。如果要将这些效果用于具有多个通道的文件，请启用此选项。

屏蔽

切换是否可以听到声音。

体积光渲染

调整声音的大小。

音调

可用于将声音的音高弯曲为更深或更高。这基本上改变了声音的回放速度，这也导致了音高变化。

播放时间

There is no setting to choose the start time when the speaker should start playing, because you might want a single speaker to play multiple times. Therefore, you have to open the NLA Editor where you can add Sound strips that define when the sound should start (nothing else, so any other properties of the strips, like length don’t matter). When you add a speaker object such a strip will be added at the current frame.

距离

扬声器属性。

距离衰减相关设置。

体积光渲染

• 最小/最大

  无论物体离多远/近距离，基于距离的体积都不会低于/高于该值。

  衰减

  距离对音量的影响有多大。此因子根据所选距离模型设置基于距离的体积变化的强度 (参阅 场景设置)。

距离

• 最大值

  如果物体距离该距离较远，则该距离用于计算基于距离的体积。该值的影响还取决于距离模型。

  参考

  The distance at which the volume is full (1.0). Set this value to the distance used for recording the sound. Usually sound effects recordings should be made exactly 1 m away from sound to get an accurate volume.

锥形

方向性相关设置。

Imagine a cone with the top at the original of the speaker object and the main axis of it facing in the same direction as the speaker. There are two cones an inner and an outer cone. The angles represent their opening angles, so 360° mean the cone is fully open and there is no directionality anymore. Inside the inner cone the volume is full (1.0), outside the outer cone the volume is, whatever one sets for the outer cone volume and the volume between those two cones, linearly interpolated between this two volumes.

角度

• 外侧

  外锥的角度，以度为单位。在该锥体外，体积等于外部体积。

  内侧

  Angle of the inner cone in degrees. Inside the cone, the volume is full.

体积光渲染

• 外侧

  外锥体外的体积。
