What is "html5-audio"
HTML5 audio element defined by W3C as Web Audio API and supported by all modern browsers.
One remark about the Web Audio API is that it does not define the format of the audio file that the browser should support. But it has to detect which formats the browser supports by the API.
The most common formats are: WAV, OGG and MP3
