For last few days I've tried to play QT files with audio tracks encoded in ac3, as 5.1 surround sound. I discovered, that even in the version 4 Arena it's impossible to play such footages.
I wonder if it'll be possible to play footages with multichannel audio in the final version of Resolume 4 Arena? I think it's necessary nowadays, especially by software from the 'media server' category...
Actually, I think the only thing to do with audio is to make possible the audio streaming 'as is' encoded in the footage... I don't know, if it's as simple as I've written above, but maybe it is, I hope
I have a client asking me about surround sound during playback. I haven't started testing, but I'm wondering if a ProLogic play is possible. To my knowledge ProLogic II is decoded from a stereo audio track.
In the next week I'm going to try to test the follow.
Use the built-in "Realtek Digital Output(Optical)" plugged into an older ProLogic II System.
Assuming your Dolby Digital 5.1 audio has been encoded into a stereo mix and your playback device supports Dolby Pro Logic II 5.1 decoding, you should have no problems passing the stereo mix through Resolume and getting a 5.1-channel surround sound.
