xiphmont’s ‘There is no point to distributing music in 24 bit/192 kHz’, Article: “24/192 Music Downloads are Very Silly Indeed” Options

Of interest, but certainly not news to anyone here is Monty's educational piece regarding the lack of value of 24/192 as a distribution format:

Some of the commentary on the internet has been not especially well informed, for example there are some crazy claims at https://news.ycombinator.com/item?id=3668310. If you're in a "someone is wrong on the internet!" correcting mood, you might want to go leave some comments in furtherance of the collective intelligence of mankind.

Yes, the "sqrt rule" applies:

1000 (but I doubt it's true) effects in serial, each of 1000 (don't know that this is true either, but it's a figure to work with) arithmetic operations, = 1,000,000 arithmetic operations

log2(sqrt(1,000,000)) ~= 10

But as you said above, this doesn't apply if the effects are internally float64 and the transport is float32; in that case, it's only 5 bits of noise.
