<p>Is it possible to do 3.1 or 5.1 audio using Flash?  We're starting a project here for an interactive kiosk, and we've been told to use Flash.  However, we also have a requirement to support either 3.1 or 5.1 audio (where 5.1 is the most wanted feature).  </p>

<p>I haven't done any high-tech audio stuff using Flash, so I was wondering if anyone knew if it was possible to do?</p>

<p>Thanks.</p>

A quick google search gave me this forum

where they state that Flash is unable to handle 5.1 audio and the alternative is to use another application that can communicate with Flash to handle the audio side of things.
I also found this blog entry from Summit Projects
http://summitprojectsflashblog.wordpress.com/2008/08/07/wave-theory-in-actionscript-3-part-4/
where they go into great detail about byte handling and processing audio samples. I'm not sure if they are using their own actionscript libraries for this, or if they are using Adobe's libraries. I'm not too up to speed on the audio side of Flash with respects to surround sound.
I think your two options might have to be either using a separate application to run your audio(which may be less stressful) or maybe getting in touch with the Summit people if you are as lost as I am over some of the concepts they touch on, heh. Good luck!
