Convert .wav file to binary and then back to .wav?
提问by Uday Kanth
I'm doing a project in java which requires me to encrypt a wave file. So, is there a straight forward process to convert a wave file into binary and back? I'll be applying an encryption algorithm on the binary data.
我正在用java做一个项目，它需要我加密一个wave文件。那么，是否有一个直接的过程可以将波形文件转换为二进制文件并返回？我将对二进制数据应用加密算法。

Most languages have utilities to read and write files in binary mode. If you happen to be on a Linux system, it's the same as character mode. In any case, it's not a matter of "converting" to binary, just a different method of reading it.
大多数语言都有以二进制模式读取和写入文件的实用程序。如果您碰巧在 Linux 系统上，则它与字符模式相同。无论如何，这不是“转换”为二进制的问题，只是一种不同的读取方法。

Yes.
是的。
File file = new File("music.wav");
byte[] data = new byte[file.length()];
FileInputStream in = new FileInputStream(file);
in.read(data);
in.close();
//encrypt data
FileOutputStream out = new FileOutputStream(file);
out.write(data);
out.close();
Of course assuming it's still a valid wav file after you play around with the data.
当然，假设在您处理数据后它仍然是一个有效的 wav 文件。

Try the Java Wav IOlibrary.
试试Java Wav IO库。
