I had a question earlier this week about playing surround sound (which PixelPower – thanks again! – helped me with) and now it’s raised another doubt in my mind.
There’s no question now that I’m playing surround sound with my ts container files. I’ve muxed them with both H.264 video and the HD tracks (either True-HD or DTS-HD) from ripped blu-ray discs. The question I know have is whether Live is actually playing the HD sound or the embedded cores in the HD tracks.
(Every HD track has an embedded compressed core – either an AC3 core or a “regular” DTS compressed core).
I can’t find any documentation to tell me if the Live supports HD at all, but even if it “supports” it, the support might be limited to simply playing that compressed track. And I can’t think of a way to tell one way or the other (I know – if I can’t tell WHY am I worrying about it? But if it’s only playing the compressed track I might as well not waste the space for the HD and go ahead and extract the compressed track. And yes, it further begs the question if I can’t tell the difference between compressed and HD why do I bother, but it’s not *quite* that simple. I have no way of really running A/B tests to conclusively determine if I could tell the difference, and I also play these files for many others who *might* be able to hear where I can’t).
Does anyone have the definitive word on this? Or any ideas what to try? I guess I *might* be able to construct some sort of A/B test (maybe make a TS container with a compressed and an HD track and switch between them, assuming I can do this with Live) but if someone has the answer it would save me a whole lot of heartache.
