Exactly, the sampling rate is fine.
Now, the amplitude... that is indeed not enough. There is an audible
difference between 16-bit and 24-bit recordings in the quiet parts.
Thankfully, DVD-Audio and SACD have both addressed that.
I agree. To bring the topic back to computers, it's that silly
facination with powers-of-2 wordsizes: 16 bits only give 96dB dynamic
range; most music that is interesting (and IMHO this _requires_
dynamics :-) needs at least 120dB (each extra bit gives you about
6dB). And unfortunately, nonlinear A/D or D/A's are difficult to
build and calibrate past 10 bits or so - no uLaw/ALaw which would
otherwise help.
See e.g. Louis D. Fielder, "Dynamic-Range Issues in the Modern Digital
Environment" JAES Vol. 43, No. 5, 1995 May.
