On Windows,...
Download the
sox-14.3.0-win32.zip file and then extract it somewhere. You can even put it right under "C:\\Program Files\\." It will create a subfolder with all the files in it.
Then you just need to use the full path to the sox.exe file:
"c:\\Program Files\\sox-14.3.0\\sox.exe" --help
Oh, you need to run it from a command prompt--this is not a GUI app. If you just double-click on it, it will just flash the help info and disappear.
Hope that helps. If it\'s a Mac, I have no idea, but it\'s supposed to be Easy.
