If more than one microphone is used even in mono, this can help the listener's brain recognize which is the direct signal and which is the reverberant signal.
If just one microphone is used, the mic has no brain, it picks up the sum of 2 signals. Direct and reverberant. So the information of what is the direct signal is lost forever.
But there are 2 microphones at different distance from the source, hidden in the 2 sums are 2 almost exactly the same direct signals with the only difference a time delay. The extra time direct sound takes to travel to the more distant microphone.
Is it possible that the brain uses this information to recreate the original direct signal from the musical instrument? So thereby making the distinction between sound of instrument and sound or the room?
Could it be that solo piano recordings with just 2 microphones will have an inferior piano sound to a piano concerto where mics are used for the orchestra section. And these microphones pick up the piano too with a meaningful delay?
Apart from the soft playing is this one reason why Largo from concerto in F minor - Bach, pianist: Glen Gould sound so nice and atmospheric but with definition?
Information for this thought was provided by Al Schmitt on Vocal and Instrumental Recording Techniques book explaining the importance of leakage of good acoustics to very good quality microphones to the end sonic soundscape.
For example the guitar microphones picks up also the singer, or the singer's microphone picks up also the guitar>
On he above example the orchestra microphones pick up also the piano which is also captured with the closser to it piano microphones.
