I myself didn’t have much information on this subject so I just did a quick google search.
From what I got out of my quick reading is that mono would play your sound through 1 speaker and stereo recording would play through 2… an analogy i came across which im going to post here:
“Assume there is an actor moving in a stage from left to right and you can hear his steps.
In a mono recording, you can hear the steps but you don’t know if he is moving left to right or right to left.
In a good stereo recording and playback, you should be able to clearly distinguish which way he is moving .
In other words, stereo gives you spatial information of the sound source.”
I hope this helped in any way
