The concept of Amplitude.js is simple, allow designers to fully control the look and feel of their audio player through the web without having to understand advanced scripting. In HTML5, the audio tag allows users to add common audio formats to their web page. The problem is that the audio playback interface is controlled by the browser. Amplitude.js puts you in control of the design by simply applying a class or ID to page elements. You can then style these elements through CSS and control your audio. Amplitude.js goes above and beyond by adding playlist capabilities (next, previous, shuffle), song meta data and visualizations. Amplitude.js is now mobile friendly as well. If it detects a request coming from a mobile device it will apply a touchstart event listener instead of a click to the appropriate elements.
