<![CDATA[Movie Audio Track Query]]>Hi all,

First I'd like to say thanks to everyone for creating such a responsive and informative forum! I've been working with Izzy for quite a few years now and the forum has been a constant source of inspiration and help.  
I'm now in the process of creating an interactive soundscape and I'm planning to use 4 separate audio channels to enhance the experience of being in the installation. I've worked out through discussions on the forum that multichannel audio out is supported on Mac (I'm running OS X ver 10.8.5) and after playing around with the Sound Movie Player, I have got four separate channels going using a stereo usb device and my internal speakers (I'm going to test this all out on one firewire audio device tomorrow) 
But while I was playing around with all the audio settings, I noticed that Izzy is only seeing 1 track audio in movie files, whereas in audio files it does see the 2 separate channels left and right. Has anyone else noticed this? When I checked in Quicktime, it tells me the mov file has 2 audio channels. Is there a reason this is happening? Do I need to export differently? 
Cheers

I've successfully got four separate tracks outputting to the firewire audio device I'm using, so now I'm really excited about finalising the interactive soundscape!
Cheers, 
Imogen

Yes, it means there's one audio track -- the number channels within that track is not shown within Isadora. (In my examples above, Isadora would have reported 4 tracks and 8 tracks, respectively.)
Best Wishes,
Mark

It's stereo...I've taken a screen shot of the info.
It's when you hover the curser over the file in the movie media bin that it says the audio is only 1 Track? Does that actually mean 1 Track=2 Channels? Just getting my head around multi tracking in Izzy for the first time :)  
Cheers,
Imogen

But is that one track stereo or mono?

I have a couple of test movies, one with four stereo tracks, and another with 8 mono tracks. The screenshots below show how QT player reports them in the "Get Info" Window.
Best Wishes,
Mark
