An audio sprite is a single audio track with multiple audio files contained in it. For HTML5 games that require the use of <audio> on mobile browsers, audio sprites are a crude but reliable playback solution. grunt-audiosprite is a Grunt plugin which wraps our audiosprite Node JS utility. For more information about audio sprites, visit the plugin page.

To install, all this from your project folder:

npm install grunt-audiosprite

Audiosprite is a multi-task which can be added to the Grunt configuration. See below for a basic example.

grunt.initConfig({
	audiosprite : {
		all : {
			// The path to save the output files
			output: "assets/audio/audio",
			
			// The uncompressed audio input
			files: "audio/*.wav",
			
			// The export filetypes
			export: 'm4a,ogg,mp3',
			
			// The export bitrate
			bitrate: 48,
			
			// Include silence sprite of 5 seconds
			silence: 5
		}
	}
});

Here are all the grunt-audiosprite options. In most cases the default values are set by the audiosprite plugin itself and not this Grunt plugin.
