Remember Dolby NR? Of course we do. When engaged, Dolby NR would completely eliminate any high frequencies and hall ambiance. Any subtle queues from instruments, foot shuffling, turning of musical score sheets, etc. was completely removed.
When I listen to my best sounding LPs, most of them have either traffic or HVAC noise that can be heard. I even have one LP whereby someone is practicing their instrument in a room adjacent to the recording. You would think that someone would have thought about this in advance, but sure enough, you can hear that faint instrument in the background.
Back to Dolby NR, I think a similar technique applies in digital land. I am confident that there are software techniques (maybe hardware hi bypass filters) that allow an engineer to remove any signal below a certain threshold. This could certain give the black background and eliminate the hall ambiance. I just queried the web and there are many software packages that have a "background noise removal" feature. My guess is that the background noise removal feature is more likely the culprit than the microphone technique. Just a guess, but at least we know for certain that both are available in the engineer's toolkit.
