audio-combiner.js

audio-combiner is a simple node.js script that will combine two wav files into one, using the open source sox audio toolkit found here: http://sox.sourceforge.net/

Note: You must have sox installed on your system for audio-combiner to work. If you're using homebrew on OS X, a simple brew install sox will do the trick.

Usage

var audioCombiner = require ('./audio-combiner.js');

// If you need to change the path to the sox executable, set the 'soxPath' property on
// audioCombiner.

audioCombiner.soxPath = './sox/sox';

// Then simply call the combineSamples() function with the names of the files, and a callback.

var file_1 = './bell.wav';
var file_2 = './explosion.wav';
var outputName = './MyNewSound.wav';

audioCombiner.combineSamples(file_1, file_2, outputName, function(err) {

    if (!err)
        console.log ('Audio files were combined!');
	
});
