04、Unity_声音管理器

1、分享一个Unity中用于管理声音的声音管理器，适合于中小型项目。

2、借鉴了很多的源码，最后修改完成，吸取百家之长，改为自己所用。

3、源码如下：

 /*
  *
  *  开发时间：2018.11.20
  *
  *  功能：用来对项目中的所有音频做同一的管理
  *
  *  描述：
  *      1、挂载该脚本的游戏物体上要挂载三个AudioSouce[可以修改脚本，动态挂]
  *      2、建议大的背景音乐不要加入AudioClip[]，对内存消耗大。而是哪里用到，单独使用PlayBackground函数播放
  *      3、小的音效片段可以将其加入AudioClip[]中，可以很方便的管理，可以通过声音剪辑、声音剪辑名称来进行音乐的播放
  *      4、该声音管理可以进行背景音乐的播放、音效的播放、背景音乐的音调改变、音效的音调改变、停止播放
