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();
		}
	}
