No.
You recorded at 16 bit, that's the resolution you have. Period.
Bumping up to 24 bit from 16 does NOTHING to increase the resolution. It might increase the file size, but not the resolution you recorded it at.
Yes.
But 24 bit resolution while recording will give you more headroom.
Milkweed, if it sounds good, it is good!
The ends justify the means.
1 - Mixing to 24 bit means that quatization errors from the DSP will fall below what we can hear. The only other option is to a) trancate back to 16 (not a very good option) or b) dither back to 16 bit (better than trucating, but add's more noise which decreases the dynamic range.)
I think you are confusing dynamic range and signal to noise ratio. No, mixing in 24 bit will not improve the dynamic range beyond 16 if the files were 16 bit to start with, but the signal to noise ratio will improve as a result of quantiztion errors falling below what you can hear, and also avoiding multiple instances of dithering.
2 - Your use of "headroom" is incomplete. "headroom" was generally considered the upper limit that you can sum audio together before "clipping". Digital audio in itself has no "headroom" at all. 24 bit audio has better signal to noise ratio, which helps create more dynamic range. That is not entirely the same thing as "headroom".
milkweed, if you were to do everything just right in a 16 bit recording that is being mixed digitally, it will sound decent enough. If you were to do the same exact thing in the 24 bit realm, I believe it would sound better. We used to use 16 bit ADAT's to a Yamaha O2R console. When we upgrades to XT 20 ADAT's, were heard a very definate improvement in the high frequency resolution of the mixes. When we upgraded to an Alesis HD24, we heard yet another improvement to the mixes. So, yes, increased big resolution has benefits. Certainly though, a poorly recorded and mixed product at 24 bit can sound worse than a well tracked and mixed product at 16 bit. The difference is in the skill. But give the same great skill to 24 bit, it will sound better. There is science that explains why, and the "experts" agree.
Don't worry about it so much. You can do acceptable sounding stuff at 16 bit. I wouldn't want to work at 16 again, but you can certainly "make do" with it.
