簡単に実験できるんだからやってみなよ

もともとM/Sで録音したものじゃなく、LRの信号を元にしたM/S処理については
日本に限らず海外でも間違った解説してるのがいっぱいある

FLStudioのマニュアルにも注意書きされてるほど

MID - Is short for Middle, it is the mono sum of both channels. Formula: Middle = (L+R)/2.
While it is called MID (Middle), it is not only the center pan (middle) sounds, as the Left and Right panned sounds are also mixed into the MID signal.
It's just both stereo channels combined and divided by 2, bringing the level down to the average of the two channels.

Unfortunately you will see MID discussed on the web as if it is only the center pan (Middle) information,
that is a misunderstanding stemming from its origins in the Mid/Side recording microphone technique.
