oh i didnt mean to argue against it.
whoever has already tried to record human voices with cheap mics, no
limiter and a bad 24 bit bit converter knows that ~110 dB _can be
close to short. the same might be true for infrasound/subsonic
applications... but i am not a diver.
i just said - that to my knowledge - the existing 32 bit converters
are all only DACs. so you currently cant directly convert from analog
to a 32 bit stream (in order to _record audio with up to 192db diff
when the filtering is done right)
in case i am still wrong with that i am looking forward to learn
about it. of course, on my to-buy list better clocking is far higher
ranked that 32-bit, but one should never say no.
-110

Roman,

Look if it was all about SNR and the capabilities of devices then
that would be the end of the story. Yea sure no 32dac or 32adc is
going to give us 192dB of information. That being said we have done
a lot of studies were we take the 32bit input or output and dither
or chop off the data to 24 bits and 99% of the time the user named
the 32 over the 24.
It's not all about what it can do, it's about how it can do. If the
DAW is working in integer mode and capable of 64 integer
accumulation then why should we inhibit it?
Thanks,
Gordon

the sabre emmits 24 bits (and hopefully claims that to the OS).
some fancy overflow bits in the delta sigma realm or additional
effects in more-than-24 is another story.

ESS has 2 parts that do 32 and AKM has 3. I have products running
on both platforms.

well for AD converters... it is. simply because there are no
converters which can do analog to 32 bit integer.
files and streams otoh can be of up to 64 bit integer resolution
and precision since MacOS 6.
