Its obviously not a fair comparison, lol.
“If you connect a Nintendo Wii to a surround system and play a game that supports surround, it sounds way better than an Xbox Series X connected to a 1981 portable radio tv with a mono speaker.” Yeah, of course it will. But when considering the output capabilities of the audio systems of each, absolutely nobody is talking about this kind of scenario.
The comparison is assuming all things are equal, which includes the skill or knowledge of the sound programmer, speaker quality, etc. The Genesis can sound more crisp, but at the cost of being only capable of FM synthesizer music, which is extremely prone to sounding piercing or tinny. High pitch notes especially are susceptible to this. The Genesis is vastly easier to make it sound worse than the SNES, specifically because of the ability to have 8 channels of samples.
I am not sitting here saying that this sounds so much worse than this because its obvious. That is also not a fair comparison.
Again, don’t get me wrong. I love FM synthesizer music, Ryu Umemoto was a god on the PC98, not a single one of his entire composed library sounded bad. But in comparison to hardware capable of sample playback, that is already an unfair comparison right from the beginning.
My point was simply to illustrate how unfair of a comparison it was, not to comment on the hardware capabilities of those two systems.
The thing is, with FM sythesizers you always know it is an FM synthesizer. Nothing you can do will mask the sound of it. However, with a sampler it is significantly harder to know for sure a sampler is being used just from the sound.
Yes, I am aware. Again, I was merely illustrating that the comparison was not a fair one. But my point remains, FM synthesizer music is very prone to ear piercing shrieking, whereas the SNES tends to produce a softer, warmer sound. Yes, it can still shriek, but you really have to try with the correct note and sample combinations to do that. Even though the Genesis can output a better range of notes, it is easier for the notes to clash as well. Mostly you will find games from those times had the audio crunched into the midtones, and this is probably because CRT speakers werent very good and pushing the audio into the midtones produced a better sound.
