Mozilla camp has released Firefox 4 beta version browser with upgrades that exposes APIs to create visuals of music and faster graphics on the web.
The highlight of the beta version being an audio API that works through HTML5 which allows developers to create visuals of music sound data in the browser, like showing the raw data associated with music, a low pass filter for music or a visual that calculates Audio spectrum.
A statement in the Mozilla blog explains "With this new API, developers can read and write raw audio data within the browser, presenting audio information in completely new ways that could allow, for example, for people to visually experience a speech or a song through Firefox."
The beta version also underscores faster graphics as a feature specifically for Windows computers. It will give default graphics support from Direct 2D API for Windows 7.
Also introduced was a security feature HTTP Strict Transport Security (HSTS) that allows Firefox 4 to remeber sites that have used HSTS protocol.
