More information at the end of this description. In addition, you can unlock advanced features in the app if you need them: learning and social features. Note: By getting this app, you'll have access to several useful and fun features related to Morse code (these are the features explained in this description and visible in the screenshots). You can run it on your iPhone or iPad and it is compatible with VoiceOver.

If you’ve got ideas for how to improve things, definitely let me know on twitter – I’m the code: # initialize # The solution starts with a bit of a strange stamp, but the rest should be pretty easy to read. wav file is stored on your machine), then execute my code. wav (and make sure to change the file path for the sf.1 object to wherever the.

If you’d like to give it a spin, try downloading one of the example morse code files e.g. It’s still pretty fragile because the example sound files I’ve been using are computer generated, so the function won’t really work on Morse code ‘in the wild’ yet. ultimately not that bad though.įiguring out how to deal with the converted audio file was actually a lot of fun – after a few hours of tinkering, I arrived at a solution (copied below) which converts audio Morse code to text. The only bother here was needing to convert the sound files from. To get these into R, I used the readWave function from Uwe Ligges’ very cool tuneR package.

To start on all of this, I found a site with a bunch of example Morse code sound files, maintained by The National Association for Amateur Radio (there are a bunch of files here – ).

Hand the paper to someone who runs the code over to another tent, ultimately to be sent to the decryption device.Īll this got me thinking – wouldn’t it be great if the ‘wire listening’ part of this process could be automated too? So here’s the toy problem all this made me think about: could I write an R function which would take a sound file (.wav) with Morse code, and return decrypted text?.

The movie features a bunch of scenes with bustling rooms full or workers intercepting (and documenting) encrypted radio transmissions, which are then passed along to Turing’s decryption device (bombe). A few months ago, I finally got a chance to see The Imitation Game (the new Alan Turing movie), which gave me an idea for a Sunday morning R hacking session.
