Play
 Usage
• Play[f,  t, tmin, tmax ]播放一段声音，幅度由作为在tmin和tmax之间以秒为单位的时间 t 的函数 f 给出。
Notes
• Play 以一种非标准方式计算它的自变量(参见 A.4.2节)。 • Play[  ,  , ...  , ... ]在任意多个信道的声音输出。 • 给出下面的选项：
| "\!\(\*StyleBox[\"\\\"Compiled\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"True\\\"\", \"MR\"]\) " | 是否为了计算编译"f" | | "\!\(\*StyleBox[\"\\\"DisplayFunction\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"$SoundDisplayFunction\\\"\", \"MR\"]\) " | 产生输出的函数 | | "\!\(\*StyleBox[\"\\\"Epilog\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"{}\\\"\", \"MR\"]\) " | 用作结尾的声音或图形 | | "\!\(\*StyleBox[\"\\\"PlayRange\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " | 包括的幅度级的范围 | | "\!\(\*StyleBox[\"\\\"Prolog\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"{}\\\"\", \"MR\"]\) " | 用作开头的声音或图形 | | "\!\(\*StyleBox[\"\\\"SampleDepth\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"8\\\"\", \"MR\"]\) " | ""表示每个幅度级使用的比特数 | | "\!\(\*StyleBox[\"\\\"SampleRate\\\"\", \"MR\"]\) " | "\!\(\*StyleBox[\"\\\"8192\\\"\", \"MR\"]\) " | 每秒应当产生的幅度样本的次数 |
• Play返回一个Sound 对象. • 参见 Mathematica 全书 : 节 1.9.13.
