Well, everybody has the right to make fun from time to time.
Of course... That's why there was a wink at the end of the post!
If had overload on the recording, that would have decreased the dynamic range, wouldn't it ?
It certainly would. But with a noise floor of -65dB, ref the peak in the recording, you could still easily have recorded this in 16-bit with a more than adequate level of headroom. A properly dithered 16-bit recording has almost as much dynamic range as it's realistically possible to get from analogue electronics; most of those extra 8 bits are completely redundant at the recording stage. Well, about 6 of them are theoretically, but in practice with a noise floor like this (which, I have to say, is pretty typical), then all of them are.
