Noise in 24-bit ADC is all thermal noise in the analog parts,
not quantisation noise. If it is measured unweighted it increases
by 3 dB if the bandwidth is doubled. But for 96 kHz, half of it
is above 24 kHz, so the noise within the audio bandwidth remains
just the same. There is no degradation.
The specs should tell you how exactly the SNR is measured. If the
A-weighted or 20 kHz BW noise increase at 96 at 192 kHz there is
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
