For those of you who are not familiar with command-line operations, here is how to use the sox program from a computer running a Windows operating system.

1. Download sox-14.3.2-win32.exe executable file from http://sourceforge.net/projects/sox (the website should detect the download appropriate for your system).

2. Once the executable file is finished downloading, it may automatically start the installation program or you might have to click the executable file to start the installation program.

3. The installation program will begin and give you a choice of components to install.  The component that is needed is "sox-14.3.2" so make sure that is checked.  Click "Next".  Select a folder where the sox program will be installed.  The default is "c:\sox-14-3-2".  The rest of the instructions assume you have used this default folder.

4. From the Windows menu: click Start-> All Programs -> Accessories -> Command Prompt.  A command line window with the title "Command Prompt" should pop up.

4. In Command Prompt window, type: cd c:\sox-14-3-2

5. Copy secret.wav from the homework webpage into the c:\sox-14-3-2 folder.

6. In Command Prompt window: (with the sound file you wish to convert on in the c:\sox-14-3-2 folder as well), type

    sox secret.wav secret.dat 

7. Now you should see the converted file secret.dat in the c:\sox-14-3-2 folder.
