@VoidX I didn't realize at first that you single-handedly implemented an AC-4 (i.e. Atmos) decoder, including the immersive audio part,
all by yourself, complete with a visualizer and renderer, and open source to top it all off. That's quite impressive. Congrats! I just gave it a try with some piece of E-AC-3 JOC (a.k.a "Dolby Digital Plus with Dolby Atmos"). Sadly
I couldn't get it to work but hopefully it's a just a quick fix away. I hope the necessary specs (or reverse engineering) will come out for MLP/TrueHD Atmos eventually.
@sarumbear I don't know what's up with you, but you might want to calm down. As
@VoidX explained, he didn't reverse engineer anything - he implemented a public specification (specifically
this one and
this one), which is quite literally
direct engineering, not reverse engineering.
@VoidX never accused you of advertising, he just said the Dolby paper you linked is advertising, which it clearly is (you can't seriously expect Dolby to be unbiased - they are trying to sell a product here).
@VoidX never said Dolby was outright lying, he just said that the paper described the very best case scenario and that the full potential of the format doesn't seem to be used in content seen in the wild (again, none of this should come as a surprise to anyone).
@VoidX reporting spec bugs to Dolby doesn't make him a "Dolby consultant" - that's ridiculous. You really need to slow down and actually read the posts you are responding to.
There is
hard evidence that
@VoidX knows the intricate details of the format very well (presumably better than anyone else in this thread), because he had to read and understand the full ~550-page spec in order to implement his decoder. There are very few people who are willing to go through the trouble of doing that kind of gruesome, tedious, deep-in-the-trenches work, especially for an open source project. That makes him a
de facto expert on the subject. If you want to accuse him of not knowing what he's talking about, I would suggest you back up your claims with hard evidence (and no, Dolby's marketing materials don't count as "hard evidence"). Right now you are out of line and making a fool of yourself.
