Mark,

I could imagine that the 24 bit recording format can really lead to an
audible improvement while recording musical instruments. I guess that
the microphone is usually placed very close to the instrument.
Therefore, there can be quite high sound pressure levels at the
microphone position. At the same time, the microphone also captures
the much softer echoes from the environment. So, it could be that
those soft echoes are indeed masked by the noise floor of the 16 bit
recording system.

Yes, I also agree that 24 bits would also be appropriate for nature
recordings in which one wants to capture both very soft and very loud
sound events such as thunderstorms.

Regards,
Raimund
