Surround sound and Youtube

The conventional wisdom is that you cannot get surround sound out of Youtube.

This is not strictly true.

Pro Logic is a method of matrixing surround sound into a stereo signal for later fetching out into the surround field by a Pro logic decoder. The easiest way to do this is with a game already in Pro Logic, such is the case with our Eternal Darkness Let’s Play. However, you can also create a Pro Logic downmix from a 5.1 discrete signal with fantastic results, which is how we did our Silent Hill 2: Born from a Wish Let’s Play.

However, recently, I found an interesting snippet on Google Support. To me that looks an awful lot like they have the ability to store and probably play back proper discrete 5.1

I’m uploading tests to determine, and perhaps it may only work on the rather experimental HTML5 version of Youtube, but this is still quite exciting for me.

I could, if this is possible, provide the best of both worlds. Pro Logic surround for the stereo channel which sounds equally fantastic in stereo or decoded into surround, and a discrete 5.1 surround for whatever that will work for.
