Firefox 4 Beta now leverages hardware acceleration to improve graphics performance for Windows users and also allows, for the first time, the visualization of audio data within the browser. If you haven&#8217;t already, you should <a href=\"http:\/\/www.firefox.com\/beta\">download it for free<a>, today!<\/p>\n<p><strong>Visualizing Sound<\/strong><br \/>\nUntil now, people haven\u2019t 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 <a href=\"https:\/\/wiki.mozilla.org\/Audio_Data_API\">new audio API<\/a> to expose the raw audio data housed within the &lt;video&gt; and &lt;audio&gt; 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. Professor and Mozilla Developer Dave Humphrey <a href=\"http:\/\/vocamus.net\/dave\/?p=1148\">has a more detailed blog post<\/a>, and offers <a href=\"http:\/\/www.youtube.com\/watch?v=oJ1UsLoPX3E\">this demonstration<\/a> to illustrate the power of this new API:<\/p>\n<p><video width=\"640\" height=\"360\" controls><source src=\"http:\/\/videos-cdn.mozilla.net\/serv\/firefox4beta\/AudioAPI.mp4\"  type=\"video\/mp4\" \/><source src=\"http:\/\/videos-cdn.mozilla.net\/serv\/firefox4beta\/AudioAPI.webm\" type=\"video\/webm\" \/><source src=\"http:\/\/videos-cdn.mozilla.net\/serv\/firefox4beta\/AudioAPI.ogv\"  type=\"video\/ogg\" \/><object width=\"640\" height=\"360\" type=\"application\/x-shockwave-flash\" data=\"http:\/\/www.youtube.com\/v\/oJ1UsLoPX3E\"><param name=\"movie\" value=\"http:\/\/www.youtube.com\/v\/oJ1UsLoPX3E\" \/><\/object><\/video><\/p>\n<p><strong>Enjoy Faster Graphics<\/strong><br \/>\nFirefox 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.

Firefox 4 Beta now remembers what sites use the HSTS protocol and will only connect to those sites using SSL (Secure Sockets Layer) in the future, helping to prevent <a href=\"http:\/\/en.wikipedia.org\/wiki\/Man-in-the-middle_attack\">&#8220;man in the middle&#8221; attacks<\/a>.
