Unzip and extract the sox file to your desktop. 2. In windows: click Start -> All Programs -> Accessories -> Command Prompt. A command-line window should appear. 3. In the Command Prompt window, type: cd desktop 4. In the Command Prompt window: (with the sound file you wish to convert on the desktop as well), type sox secret.wav secret.dat if this fails, try ./sox secret.wav secret.dat 5.
