clap-trigger v2.2.0

Clap detection trigger for nodejs

===

Motivation

I just bought a Phillips Hue lamp. My son and i want to switch on / off by clapping hands (see working code here http://pastie.org/10692960)

This module conforms to "strict minimal composition" (use browserify and you'll get the tiniest possible code, with all underlying componants fully tested)

How

This module relies on sox ("Swiss Army knife of sound processing programs"). Sox is available on all platforms.

Windows requirements

Have sox.exe available in your path (download http://sox.sourceforge.net/)

Linux requirements

apt-get install sox
gpasswd -a [username] audio

API

var engine  = require('clap-trigger');

var trigger = new engine(); // options here

trigger.start(function(){
  console.log("Stopped")
});
 
trigger.stop(); //stop listening

trigger.clap(function() {
  console.log("Simple clap here");
});

trigger.claps(2, function() {
  console.log("Double clap here"); 
});

Testing

npm test

# current code coverage is 100%
