Re: More on "self dithering" and actual noise levels in recordings

*** I think you meant to swap the numbers ***

No, read it again. The statement is as intended.

*** But I don't think adding noise is necessary if the same high-resolution signal is truncated to 20 bits. ***

It doesn't matter what you think, in reality dithering at 20 bits will make a difference, just like dithering at 16 bits. It may be harder for our ears to hear the difference though.

It's probably a moot point though because I can't think of a valid reason why someone would want to truncate a 24-bit recording to 20-bits. Do you?

*** Note that video color is not something that is hurt by dynamic range, since the color range is finite. ***

I'm not sure what you mean here. Try comparing an image with 8 bit colour vs 16 bit colour vs 24 bit colour and tell me whether it's "hurt" by dynamic range or not.

*** Which is a lot more benign than such application applied to audio signals. ***

I would actually argue the opposite.
