I don’t know if you will agree with me on this but I have noticed that the rate at which Mozilla rolls out beta versions of the browser have improved quite considerably. Firefox 4.0 Beta 5 is another proof of this. The latest beta of Firefox 4.0 brings a couple of new features which we discuss after the jump.

The two new features making there way to your computer are none other than the all important hardware acceleration and the new and exciting audio visualization ability.

Here is how Mozilla explains the new sound visualization feature:

Until now, people haven’t had the ability to interact with sound on the Web in all the creative ways that video and images allow. Firefox 4 Beta introduces a new audio API to expose the raw audio data housed within the <video> and <audio> elements in HTML5 to redefine how people experience sound on the Web. 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.

Here is how the hardware acceleration in Firefox 4.0 beta 5 works:

Firefox 4 Beta now takes advantage of the built-in graphics hardware in Windows computers with DirectX 10 to improve graphics performance. On supported hardware, Firefox will use Direct2D by default to speed up the display of content on graphically intensive websites, giving more power to the Web.
