Motion sensing using the doppler effect

[malsploit]

This is an implementation of the SoundWave paper on the web. It enables you to detect motion using only the microphone and speakers!

How to use it

Just run it like this

doppler.init(function(bandwidth) {
  console.log(bandwidth.left - bandwidth.right);
});

See more in example.html. (Note that doppler uses navigator.getUserMedia, which can't be run on the local filesystem, so you'll have to start a server to run this.)

Read more about the theory of how this works on the github-pages site.https://github.com/DanielRapp/doppler
