Morse Code World Audio Decoder (in development)

This software is under active development, does not look pretty, and may not work. It is here for people to test and provide feedback.

Upload an audio file to analyse, or press the Start Recording / Stop Recording buttons to record from the microphone (it will not appear to do anything until you stop recording). The audio will then be analysed and compared to the speeds and message below if they are defined, or to the perfectly timed version of the decoded message if not.

This pitch will be analysed, if defined, or the loudest frequency if not: Hz

This speed will be used, if defined, or a best guess will be made if not: wpm

Optional message to compare with:

Use the mouse-wheel to zoom the charts, then drag to pan. Mouse-over the following buttons to highlight the different element types:
