To me, this makes about as much sense as 96khz/24-bit (or even 32-bit) FLAC recordings. 44.1K is already capable of reproducing the highest pitches the human ear is capable of hearing (and a few pitches that can’t be heard), so there’s no reason to go higher. All the extra kilohertz will do is make it possible to record dog whistles… which is useless (even for dog training), unless you have some high-tech speakers that can reproduce these sounds. IDK about the number of bits, but 16-bit tends to sound quite nice, assuming the listener has good headphones/speaker, and that the file doesn’t have any lossy compression artifacts.
there’s a reason why manufactures don’t care about 12-bit technology. 8-bits per color is enough to create the same colors the human eye can see. Perhaps if we could see more colors, this technology would be useful.
Also, I should probably mention that, because most videos are stored in some YUV format (instead of pure RBG), the colors are reduced before the actual compression. Therefore, most recordings can’t even take advantage of 12-bit anything.
