Convert .wav file to binary and then back to .wav?

Question

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.

Answer 1

Yes.

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.

Answer 2

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.

Answer 3

Try the Java Wav IO library.

Answer 4

you could try the plugin : JLayer
