as usual, you have missed the pointas an extreme example lets say that the gain is set so that the signal never exceed 12 bits. then effectively the 24-bit PCM recording is indistinguishable from a 12-bit PCM recording. the other 12 bits are never used - therefore "wasted."
*** Usually the input gain of the recorder channel is adjusted just below clipping ***
that is fine if you can predict what the loudest part of the signal will be. in a real life situation, you often can't - that's why you need to leave about 2-4 bits of "headroom" just in case.
if you have ever recorded a live performance and successfully avoided clipping you will know what i'm talking about. i've had too many recordings spoiled by an inadvertent clip caused by too aggressive a gain setting that i stick to my 2-4 bits of headroom philosophy.
