The music kicking up towards the end in the same way Mariokart Wii does when going through the menus was a lovely touch!

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!

<a href="#" class="seekto" data-time="72">1:12</a> 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

I've just realised but Scruffy rarely actually uses in-game footage, they're all just drawings. That's honestly really cool and it's a testament to how well he can get his point across without even needing to actually show the game

I wanna applaud that while lots of KZfaqrs 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.

Scruffy: *uses the doppler effect on the last trombone note like a car engine* Me: He did- HE DID THE THING!

goddamn, he even had the pawn move a bit as he placed it down at <a href="#" class="seekto" data-time="133">2:13</a>

I really loved the visual take on this, your character look like the Jerries from Soul, idk if that's intentional but I like it!

Full body Scruffy showing up hit me like a ton of bricks

<a href="#" class="seekto" data-time="107">1:47</a> that transition from 2D to 3D made me really happy for some reason

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! 🥂

<a href="#" class="seekto" data-time="22">0:22</a> That animation is just so dang adorable. Please do more of them!

They should have taught the doppler effect like THIS in my physics class! It's miles more entertaining!

Can I just say I'm absolutely blown away with the entirety of this video? The clarity in explantion, the 3d and 2d animations, the sound, music, everything in this is absolutely incredible and I can see the huge amount of effort put into it. Fantastic job Scruffy!

I love the ending credits mimicing mariokart wii's menu music. When the checkerboards moved at the top and bottom of the screen at <a href="#" class="seekto" data-time="485">8:05</a> and the music began, I immediately knew what was going on.

This is beautiful

Oh my god! You really stepped up the animation in this one!!! :0

i never really thought mario kart had such a deep sound engine

"aaaaaAaaAAaaaAAAAAAAAAAAAAAAaaaaAAaaaAaaaahhhh!" -what my friends hear when im playing 200c with the p wing on baby park

This guy needs to make an animated series or something because he's got skillz

For those of you not using headphones, Scruffy really put in the effort to have sounds move from one side to the other. It really *does* feel like a car is racing by!

You should make a pocast about music cause youre voice is wierdly calming

The blend of 2d and 3D animation was surreal as hell

pure awesomeness

Wow. The animation of these little "get-to-know" videos is really getting more and more detailed. Makes the visual learning presented even more intuitive! :D Always did love the Doppler-ing on powerups, especially. Was always very amusing to hear the intense tunes of a Super Star behind me and swerve out of the way, hearing it trail off as whomever continues their short-term power trip onwards.

The quality of these videos is improving so fast it'll cause the doppler effect!

<a href="#" class="seekto" data-time="134">2:14</a>--oh, the pawn jittering when you let go, that is FANTASTIC.

Imagine being buddies with Scruffy and he just comes over to ur house and asks if you want to play Mario Kart so he can “test some things”. Would 1000% be a part of that

The Doppler effect is cool!

Why does his "Hello, I'm Scruffy" line ALWAYS give me a Big Smile? :)

I’m at <a href="#" class="seekto" data-time="119">1:59</a>. Just want to say “Damn the production quality on this. Great!”

This is a really good explanation for the Doppler effect, schools could probably use this video to explain it better than any textbook could

this is such a high quality episode omg animated scruffy is adorable and the way you explain things is very clear and concise (there used to be fast captions at <a href="#" class="seekto" data-time="306">5:06</a> but they're gone now because they weren't supposed to be there, for reply context)

I always love to see the dopppler effect simulated in games, not even racing ones just games in general, it's like a hidden gem that only a few notice and appreciate.

I literally just learned about the Doppler effect in physics today and I have to say this was a lot more informational and fun. Nice stuff

I thought I was the only one who appreciated the immersive sound of Mario kart wii

really love the cute little scruffy "ʰᵉˡˡᵒᵎ"

I was here when it said “FINAL” at the end of the title

This is some true quality content. I'm glad this exists on this God forsaken platform.

Honestly I love the design of Scruffy's little… Persona? With the curly bracket hair, square brackets for the glasses, it's super clever

Absolutely phenomenal breakdown of these little game audio solutions! I love the focus on WHY many of these decisions are made, rather than just HOW... in practice, that process of problem solving is 90% of the job, and the actual technical stuff just fills in the gaps.

GOD I LOVE HOW YOU FOCUS ON SOUNDS IN VIDEO GAMES!! ITS AMAZING MY GUUUUUUUY!!!

Scruffy would be the best university professor ever He makes seemingly complicated topics so easy to understand

Finally someone explains this sh¡t simple enough.

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.

the production quality is OFF THE CHARTS on this one! i noticed at the end with the What I Love part, you did a doppler effect pitch shift in the song itself as the car went off screen after leading the camera to the text. GENIUS

You basically just applied differential equations to sound design and I love it

<a href="#" class="seekto" data-time="224">3:44</a> I REALLY love the edit here where the music you used exhibits the Doppler effect for more clarity. That’s really helped me understand the concept of frequency change. I appreciate that level of care and detail.

I like the animated scruffy, he looks nice

i love this scruffy avatar design

<a href="#" class="seekto" data-time="109">1:49</a>'s animation is soo good. Is something hard to pull off yet you did it amazingly

This blew my mind in all the best possible ways. Random YT suggestions go right sometimes!

I thought this was a music channel, but this is math, my brain can't comprehend this

scruffy, this is so good. you’re breaking into “game dev tutorial” ground here with the part on how the doppler effect is made!

I was expecting Futurama levels of Scruffy, but I got much much more. A more sophisticated Scruffy, per-se?

we *just* happened to go over this in my physics class, so thanks for helping solidify this with an example i can understand!

Thank goodness I decided to stay up late tonight, Scruffy's posting a new video! :D Edit: HOLY, the quality of his videos went to a whole new level!? Wild!

Love when games use clever details like this in the audio design. But don't other racing games do the same? Saying this as a person who doesn't play most racing games

I’ve always known about the Doppler effect and what it meant, but your explanation using the ‘bunched up’ and ‘spread out’ waves has really helped me actually understand it for the first time.

Our quick understanding of the doppler effect (ie rising pitch = approaching object) is also used to tell us when red shells are catching up with us, as the pitch and volume rises as they get closer, giving us a general concept of when we're likely to get hit.

The production value here! Insane!

Now I want to see an entire racing game in this style

I don’t know what it is, but the sound, looks, and feel of wooden blocks and toys are just very calming and amusing.

Wow, there is really nothing else on KZfaq like Scruffy... blown away by this video, the animation quality, the clearly well-researched topic, the concise clarity of complex concepts, and just the fun, interesting, nerdy-ness of it all! Can’t wait for more to come, keep up the good work, Sir Scruffy!!! 👏🏼 :)

THE ANIMATION WAS SO AWESOME!

The animation in this one reminds me of those children's shows from the early 2000's-2010's that only Aired at 3 in the morning

Its amazing how in any videogame, especially mariokart, millions upon millions of computations are made and a result of those computations are translated to visual and audio effects

<a href="#" class="seekto" data-time="49">0:49</a> 5d6-dy6-klf smm2 Is that a super mario maker 2 level? Okay I have to go see what that level is. ... "Thwomp Race" by ScruffySMM Ooooooo! Well that was dlightful! (Oh hey! I got the world record! 31.416s which are good rounded digits of pi, so that’s fun!)

This man made a whole ass educational 3D animation for this video

The Doppler Effect is probably one of my favorite bits of sound design. Not only is it useful, it can also be used to humorous effect. My favorite example always being when someone is falling, begins yelling, and passes a listener.

In certain scenarios, the Doppler effect can be funny as shit My personal favourite is Wario screaming as he passes you at Mach jesus

Thank you so much for this formula where you subtract the old and new distance! I'm coding a Doppler Effect Simulation and I didn't find the formula I needed, not even on Wikipedia and this helped me so much that I was able to finish the Simulation! Thanks :)

im so glad someone finally talks about the doppler effect in mario kart, I always found it so cool whenever someone passed by with the star and it really felt like the music followed that guy, it felt so impactful and thrilling to be passed by someone with a bullet or just to hear their horn beep

"hello, I'm scruffy." Yes. Yes you are

The absolute best part of this video is <a href="#" class="seekto" data-time="530">8:50</a> - A little not to the whole explanation that is well incorporated. This video is insanely well produced. And so clean too.

Love this! Doppler effect is one of the (many) little touches that I absolutely take for granted in games, and forget that it doesn't just "exist" in the game world until someone works it out.

Every time I see Scruffy upload I get so excited. His videos are such high quality and the aesthetic is really unique. They're calming, educational, and entertaining. As a music/sound effects, gaming, and animation nerd, I really appreciate all the effort he puts in these videos. It’s amazing how much more advqnced the animation has become but the content has stayed digestible and entertaining. Keep it up Scruffy!

<a href="#" class="seekto" data-time="399">6:39</a> VERY sneaky coin sound!!!

What's interesting is how I never consciously noticed the Doppler effect in Mario Kart, but by simply seeing the thumbnail for this video, it was able to make me realize just from memory that it's there, and begin to appreciate it.

this is even easier to calculate if you're using velocity to calculate movement, as opposed to the other way around.

Scruffy's character design is so cool!! I love the squiggly parentheses for hair, reminiscent of his channel's writing and logo. Scruffy is a lover of small details, and so am I.

Scruffy explaining the doppler effect: Me thinking his little avatar is the cutest thing in the world like seriously: Edit: And of course it's another wonderful video, this time with 2D and 3D mediums being used together seamlessly. I always love when you upload What I Love because they're always so well put together.

It's incredible how so many game designers use this every day and never question how it's coded, or even notice it's there. Most of the time it's just "Alright, that sounds good." and moving onto something else.

phenomenal editing and animation, I love it so much its everything I love from the older videos and just so much more! please keep it up cause it just looks and feel amazing

Oh my gosh Scruffy! Your content just keeps getting better. I absolutely love how you blended 2D and 3D animation so smoothly. I always love hearing you talk about sounds and music and I find your videos so engaging. Also, your animated sona is super cute. Keep at it! Love it all!

guys he's becoming stronger, he has entered the third dimension!

I never thought about this, but now that mario kart 7 introduced underwater racing is the speed of sound changed in the doppler effect programming as well? Maybe it's based on real measurements, and it changes from 343 m/s in the air to 1484 m/s in water. I might look into some datamining to check, it's interesting to think about

This was absolutely fantastic. The visual aids are so clean, all the little Mario Kart motifs in the ambient music (My ears picked up on the various references, no matter how small! That was so cool!) I always wanted to know a little more about how this system works, and this was the best way of explaining it!!

i love this little representation of scruffy, so cute! and perfectly matches the voice

Let alone the amazing step up in animation here, I am constantly just fangirling over how scruffy draws himself! I don't know if the design supposed to be based off of him or not, but it is just wonderful!

The absolute production quality in these videos are amazing! Thanks for explaining these things to us

mariokart wii is my favorite mariokart to date. the powerups were perfect honestly, the achievements obscure, and boy do we love the music! well done scruffy, this was executed absolutely perfectly, visuals, examples, and all

The inclusion of this 3D animation just took your already incredible videos to another level. Absolutely fantastic Scruffy I'm in awe.

Scruffy really out here looking like Terry from Soul Seriously though, loving the step up in the animation, it’s hella cute

While I loved listening to your music arrangements these past few months I'm so excited for your return to more long form content! The effort and care put into this video has just absolutely blown me away. As always looking forward to more excellent content scruffy!

this is literally the first time someone has explained the doppler effect to me and have it make sense. i thank you for teaching me what my 9th grade physical science teacher failed to teach

YOOO THE ANIMATION IS SO GOOD!

i love this new animation style!

I love that the Super Star used to have the effect on it in Wii. It made it funnier when you got blue shelled and heard the other karts overtaking you

phenomenal video!!! you got your points across and its insane how something so minimal can change the way we get immersed when playing.
