Mario Kart and the Doppler Effect

[@gamesbydesign9156]

Something interesting about Mario Kart is that it's really important for players to know what's happening off-screen. Sound design really helps with this, since you can HEAR a hazard (shell, star, bullet bill) before you SEE it. On top of that, the doppler effect gives you a really solid gauge of how quickly that hazard is approaching and when it'll catch up to you. It's a really clever implementation of sound design in games that seems to get overlooked a lot!

That immense panic you feel when you start hearing a dopplerized Starman effect slowly speed up behind you

[@duckysnake]

In Mario kart 8 it gives you an indicator on screen though

[@dullicecream]

@@duckysnake It doesn't grow in size though as whatever is behind you gets closer. (and sometimes like online for example it doesn't even show up) As well as it's only for red shells, bullet bills, and the star. Green shells, fire balls, and the boomerang don't have that pop up.

1:12 I always loved how exaggerated the Doppler effect was in Mario kart Wii because it made it feel like those items would actually physically come into contact with you because of how set in reality the audio was. It felt like, If you paid close enough attention, you could hear exactly where the person using the item was based on audio alone

[@MisterMoodyHere]

and how he made the horn sound like it’s beeping to the mario theme song omg I love it

I wanna applaud that while lots of KZbinrs end up putting unnecessary visual effects that don't actually add anything and are mostly there to give the illusion of being professional, Scruffy used visually interesting effects that both aid what he's trying to convey and are fun to look at.

[@ariaofthe6strings230]

The animation in this video is such a genuine treat. It reminds me of those old school Pixar animated shorts. Masterpiece. The explanation in theory, and the science of it all while applying the mathematics involving physics. I love these videos because you take the time to appreciate the genuine love and care that most consumers NEVER appreciate. As someone who aims to become a composer, this warms me heart. Thank you for acknowledging the love and care put into the nuances of games from Nintendo, and many other cult classics. Cheers! 🥂

my favorite part of the use of this in the series.... it insinuates the music from a power-up is a 'real-life', tanglible, not-meta occurence 😭 like we assume video game music to not be part of the "material universe", but that doppler effect takes you out of that for a second in a way that's genuinely super funny.
