In a previous article, we had managed to snif & record RF signals, decode it and reproduce it with an arduino.

Thus, even if you can visualize the wav form in Audacity (or any other sound editor), it is not easy to « read » the signal.

The attached software (source code provided) will not only display the wave form, but also shape it as a « square » form and eventually provide a textual reading (high for xx ms, low for xx ms, …).

This makes it easier to reproduce (from an arduino) or eventually make a better guess at what the signal (or part of it) actually is.

Below :

1-the original wave form

2-the square form

3-a textual reading of the worm

Hope this helps others 🙂
