That 1st order, 4 channel method of Ambisonics is elegant as he describes and it is what my player uses. 4 channels are certainly not a stretch to achieve above the current 2 channel stereo signals most commonly used for music and video.<\/p>\n<p>In second contrast, the second presenter, Andrew Mason does a good job of explaining exactly why Ambisonics has languished in relative obscurity. He is absolutely right however I&#8217;m trying to demonstrate how a simple shift in paradigm might change that.<\/p>\n<ol>\n<li>The ability to decode an ambisonic stream is on the cusp of being available in nearly all major web browsers thanks to <a href=\"https:\/\/www.google.ca\/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;cad=rja&amp;ved=0CD8QFjAA&amp;url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FHTML5&amp;ei=YPbaUbWgD8e70AGv-4CwCQ&amp;usg=AFQjCNFax33ZUc9vQLc3WHs-8Db09pMkpw&amp;sig2=g1PEIX8ze4Xf1Ue1QRUw1w\">HTML5<\/a> and the included <a href=\"http:\/\/chromium.googlecode.com\/svn\/trunk\/samples\/audio\/samples.html\">Web Audio API<\/a>. <\/li>\n<li>The possibility to dynamically navigate a 1st order Ambisonic soundfield offers an immensely enjoyable and unique experience which defies comparison to traditional surround. &nbsp;Resolution is not a large issue when the playback system is not the only means of locating sound events in the soundfield. &nbsp;In short, being able to turn your head in a soundfield makes a huge difference.<\/li>\n<\/ol>\n<div>Hopefully both of these are or soon will be demonstrated in my&nbsp;<a href=\"http:\/\/test.darylpierce.com\/listenaround\">panoramic audio player<\/a>. &nbsp;I&#8217;m not trying to suggest that Ambisonics in this panoramic context is a replacement for existing surround audio strategies. &nbsp;What I&#8217;m suggesting is that the current strategies are well designed and suited for installation, for public exhibit. &nbsp;They are not so well designed for being light-weight, accessible to individuals or easily scale-able.&nbsp;<\/div>\n<div><\/div>\n<div>If we are willing to accept the possible resolution shortcomings of Ambisonics (let&#8217;s be honest, we&#8217;ve accepted much worse from standard stereo reproduction for decades) then it&#8217;s obvious 1st order ambisonics is light-weight, accessible to individuals (thanks to Web Audio API) and easily scale-able (from mono to stereo to multi-speaker playback).<\/div>\n<div><\/div>\n<div>A short list of possible uses:<\/div>\n<div>\n<ul>\n<li>panoramic dramatic audio broadcasts&#8230;imagine the radio dramas of the past but with the ability to turn around to follow the sound of the action<\/li>\n<li>panoramic cinematic production with fully navigable, synced audio and video elements.<\/li>\n<li>sound installations synced to geographic locations, accessible via a website on a mobile device<\/li>\n<li>voip style teleconferencing with the ability to virtually spatial locate within the conference room<\/li>\n<li>live concert recording and reproduction<\/li>\n<li>virtual tours<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>In this article I would like to explain more why I have attempted to build an&nbsp;a panoramic audio player in html5&nbsp;and how I am hoping such ideas can be used.
