首先取一个wav文件，其次找一个wav文件格式简单符合pcm编码的，也就是文件的第14字节位置要为1
确认此wav文件此处为01 00 然后进行解析
然后我们还要知道他的位宽（8位还是16位）、几声道（单声道还是双声道）
14h位置为1代表为pcm编码格式的wav文件
16h位置为2双声道
22h位置为pcm位宽 16
8bit也就是8位也就是等于一字节
8bit单声道用一字节表示一次采样数据
双声道用两字节，前一字节为第一个声道后一字节为第二声道的采样数据
我们16位双声道用四字节表示一次采样数据
前两字节表示第一次采样的一声道数据，后两字节表示第一次采样的二声道数据
那么我们开始解析，一般这种文件文件头为44字节，所以去掉头部44字节后面就是实际的数据。
最终我们要解析成波形图。
双声道就是两条折线图的意思
先解析第一个点02 00 02 00 也就是
第一条折线图的第一个点的y坐标是2，第二条折线图的第一个点的y坐标也是2
第一条折线图的第二个点的y坐标是1，第二条折线图的第二个点的y坐标也是1
。 。

。 。
。 。
以此类推最后画出波形图
好了我们这个音乐是嘟的响一声
如果我们要把改成两声就把数据区域复制粘贴插在文件尾，然后修改28h-2bh位置的数据乘2即可。
