A while ago, I worked up a simple little program that could generate both computer generated speech and Morse code at various speeds to make up some sample recordings I could use to brush up on my Morse skills. I apparently left it in a pretty broken state though: it could use some work. But it does generate pretty pretty reasonable sounding audio using the voice synthesis system on the Mac and my own relatively nicely filtered morse wave forms. I should clean this up, and then use it to brush up on my code skills.
