java wav文件转pcm文件

其实wav文件比pcm文件多44字节的头文件，所以直接去掉头文件就行了

public static void WavToPcm(String src,String target) {
try {
FileInputStream fis = new FileInputStream(src);
FileOutputStream fos = new FileOutputStream(target);
byte[] buf = new byte[1024 * 4];
int size = fis.read(buf);
fos.write(buf, 44, size-44);
size = fis.read(buf);
while (size != -1) {
fos.write(buf, 0, size);
size = fis.read(buf);
}
fis.close();
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
