Sox in Your Voice Over Toolbox

Sox stands for "Sound eXchange," and it is spelled S-o-X, with the
letter "o" being lower case. SoX is presented as the "the Swiss
Army knife of audio manipulation," and indeed it is. SoX is a
command line tool, no GUI. But don't let that deter you. We'll go
over some of its capabilities that will make you glad you have it
in *your* audio Toolbox.
