cwwav takes one or more text files (or text read from standard input) and converts the text into an audio file (wav or mp3) containing the CW (Morse code) representation of the text. It's useful for generating practice files if you are learning CW and want to practice by listening to text. It's a very simple program but it is designed to do what it does well.
