Mono vs. Stereo

What is the difference between stereo and mono recordings? What are 2 things that you found interesting in this article? Why?

    The primary difference between stereo and mono recordings are the amount of tracks that they have. Mono, short for monophonic, have a single channel---meaning that any audio will sound like it comes from a single point, no matter how many speakers there are. As for stereo, short for stereophonic, the audio goes through multiple channels and can give the illusion of being directional. Because of the lessened complexity, mono recordings are cheaper and easier to make whilst stereo recordings are more expensive and require more skill to create. Two things that I found interesting in this article were how stereo became popularized and the techniques to record stereo sound. It was interesting to learn that stereo sound had existed as early as 1881 but hadn't become popular until the introduction of magnetic tapes. Regarding the ways to record stereo sound, I found the X-Y and M/S techniques really interesting. When I was trying to think about how stereo was recorded, I pictured the A-B method. So to see two other techniques were very intriguing. I never even knew that bi-directional mics existed prior to this article, besides those strange mics that look like ears that ASMR content creators use.
