Jiro's pick this week is Waveform Generator by Maxim Vedenyov.

I really like the concept of this tool. Sometimes, I have a need to create data for demonstration or for testing of a function. For that, I often use the function rand or superimpose multiple sin and cos functions.

Well, wouldn't it be great if I could graphically create my data? That's exactly what Waveform Generator allows me to do.

By moving the green control points, I can create a single cycle of any arbitrary waveform. The actual application for this tool is audio synthesis. The constructed waveform can be played and saved as a wav file.

This has inspired me to create a general purpose data generation tool. I'll post it on the File Exchange once I create it (unless someone beats me to it!)
