Audition CS6导入M4A

最近想学学调音，现在开始学习Audition，发现不能导入m4a，老是提示：

错误: We were unable to open this file using any of the currently available importers. If you would like to try using the Dynamic Link Media Server, please go to Preferences > Media & Disk Cache and enable the option "Enable DLMS Format Support" and try to open the file again.

我们需要修改：编辑→首选项→媒体与暂存盘→将Enable DLMS Format Support勾选上就可以了
