Thank you. That helped, a little.
I’m not really convinced (not having heard it).
I have worked in computer graphics, initially with floating point math on big computers, but when the PC arrived it all became integer math because that’s all the CPU could do in real time. And that lead to a generation of engineers who thought that a line had to be an integer number of pixels wide. But that is clearly wrong, it leads to limiting decisions for algorithms. In a grown-up product like Photoshop, it is certainly possible to draw a line of 1.374953 pixels wide, at an angle of 77.4963 degrees from the horisontal.
What I read in these papers is that only integer math is acceptable, in terms of sound quality, and to preserve integer math they have come up with a clever algorithm to support a fixed set of volume attenuation ratios that can be expressed as fractions. That’s clever.
But it seems to me a step backward.
I’ll be intrigued to see how it performs in practice.
