>>3534451As an expansion of this I need to actually talk about the plugins used for pitch correction, and how a lot of them are straight up not translated to Japanese. The biggest autotune plugins I'm aware of are Antares Autotune and Melodyne (the one I'm most familiar with). There are a ton of other autotuning plugins that are less effective and have harsher artefacts. I can only imagine the japanese autotuning plugins are on that level, or they might just be using default pitch shifting tools which is absolutely not what you want to do. Vocal pitch shifting works in a different way than most instruments and requires much finer tuned controls and much more complicated algorithms due to all the different things a human being can say compared to a piano or something. This is why you can hear the autotuning on Rikka fuck up more on specific syllables and pitches than others, whatever they're using to autotune him is not a very good program. It's not just that the autotune is unneeded, it's that from what I've done in 5 minutes of research, the Japanese are still not at western standards for vocal correction technology. The plugins are not translated to japanese and a lot are just not available to them even if they could read english. I have to use this as an example of what effective pitch shifting sounds like because it's still fucked up enough for people to understand.

If you listen to Spiral Tones you can almost hear semitone jumps in the pitch. Now I can't prove this but I have a theory that whatever system is being used to mix these songs is probably working with an autotuner that was meant for fucking Black Eyed Peas style robot voice stuff and they just turned the effect down to make the jumps less harsh. If I'm going schitzo pls forgive it's 5:00 AM but I really think they're tuning the vocals in all these songs based on a piano scale and not human vocal ranges.
