Two concrete examples of misunderstandings in the paper is the information about "diffuse tail" and "RT60". The first isn't used correctly related to small room acoustics. The other isn't relevant to small acoustics at all. That's well known for experts in small room acoustics. But no, I don't have time to teach people online fundamentals which and takes a lot of time and bickering back and forth, and it would also be detrimental to this thread and the thread starter.
Wow, you really like to take things out of context. First, "small room" was not a given in the paper and your criticism is out of context. Then, of course, one can create a moderately diffuse tail in a smallish (not tiny) room with a lot of work (that isn't worth it for a couple of obvious reasons) but it's probably better not to have much of a tail (like I said, I'm not at all fond of LEDE), and finally, a T60 is absolutely measurable in such places unless they are too noisy, even though they are unlikely to be long, pleasant, or useful. Of course, I'd probably use T20 in most such places, but you already knew that, didn't you? Your claim to "doesn't apply" is simply evidence you don't know how to apply it as far as I'm concerned. I certainly labor under no such difficulties.
No, the OP's small room is not likely to be either diffuse initially nor have any useful T60 given the level of absorption he shows with his material. Does he want diffusion? What is his goal? We don't really know yet. That's a different issue to the perceptual issue that he asked about, now, isn't it? Yes, he had the perceptual issues wrong, that happens with people just starting out when they are learning. One of the ways people learn is by asking questions, right or wrong, and then a dialog an ensue, unless somebody drives by to pick a fight.
OP - what are you wanting to actually do in your room? That's where I was trying to get. Do you want imaging, envelopment, what? 2 channel, 5 channel, 7 channel, what? I was trying to work my way into finding out what you're thinking of when the bomb dropped. Do you know if you like LEDE-style for 2 channel?
A "diffuse tail" is a term in small acoustics which is achieved with the treatment of diffusers in order to deal with spaced specular reflections.
Yeah, I agree. It's what I showed the envelope of. Why do you feign disagreement?
So, then, your entire objection (which you could go to the lecture to listen to to find out) is that I drew the envelope of the diffuse tail? Any words about how diffusion happens, why it becomes probablistic, when it becomes probabilistic, etc, now? Would you be happier if I filled the envelope with white noise (I know, it wouldn't be white, but it would look pretty.).
