i was not going to post to this thread, but it is just too tempting. as an
archive person and a field recordist, i do use 24 bit whenever i can. in an
archive you never truncate anything, whether you can hear it or not (somebody
else might). as a field recordist, it just means i can set my levels about 18
db lower and never worry about the occassional overlead. (i have had serious
microphone overloads with the sarus (a red necked stork) from a few hundred
yards away. for publication you can dither down to 16 bit, but there is a world
of difference with dither and without dither, audible without anything more
than a decent pair of headphones. (this is something i use to teach.)

Subject: Re: [Nature Recordists] Re: 16 bit vs 24 bit Information Theory
Hypothesis
Correct, sorry for the confusion. But my point is only this. Instead
of letting it add the 8 zeros, why not record with those bits filled
with 'real' material?
But thanks for the correction, you're right, it's not 'conversion'
per se. My point was only that taking 16 bits into 24 bits will not
create any better sound in and of itself, so in my mind, recording it
with the 24 bits there before processing is better than converting a
16 bit into 24 bit for processing.
But honestly, I'm now 100% done with this thread. People have the
information they need. Both sides have prevented their cases, and
it's time for the jury to retire and figure it out for themselves. I
think at this point very little 'information' is being presented
anymore, just bickering.
