Audiosprite is a node.js ffmpeg wrapper to concat small audio files into one single file. It even allows you to define the gap between each file.
It also outputs a howler.js compliant JSON configuration file for simple copy and paste. This saves a lot of work, when using audio sprites in your web projects.
