How to Make a Speed-Up Version of the Hooda Math Theme
People keep posting links to the Hooda Math Theme Song But Really Fast and asking where to get it or how to make one. The original theme is short — maybe twenty seconds at most — so speeding it up doesn't require any fancy tools. You just need a basic audio editor and a copy of the original track. I've made a dozen of these over the years, mostly because kids in my household found the regular version repetitive and the sped-up versions are easier to tolerate on a loop. The process itself is straightforward, but there are a few things that go wrong if you don't pay attention.
Where to find the Hooda Math Theme Song But Really Fast
If you're looking for an existing version rather than making your own, searches for the Hooda Math Theme Song But Really Fast will pull up YouTube uploads and a few SoundCloud links. Most of them are just someone importing the original into Audacity and cranking the tempo. The quality varies. Some are clean. Others sound like chipmunk noise because the pitch wasn't adjusted alongside the speed change. Start by finding the original audio. The Hooda Math theme plays on the site's homepage and can be recorded with any screen capture tool that includes system audio. I use OBS set to record desktop audio only. That gives you a clean WAV or MP3 without background noise from the rest of the room. Once you have the file, import it into Audacity — it's free and does everything you need. Here's what I do next:
First, select the entire track. Then go to Effect > Change Tempo. Set it to roughly 175 to 200 percent. That range gets you into "really fast" territory without turning it into unintelligible garbage. If you go past 250 percent, the notes start overlapping in a way that sounds like a malfunctioning music box. Next, apply Effect > Change Pitch. Set it to zero or very close to it. This is the step most people skip. If you only change tempo without adjusting pitch, the track gets higher in key as it speeds up. That's why so many versions online sound shrill. The Change Tempo effect in Audacity uses the SSMP algorithm, which preserves pitch while altering speed. That's the difference between something listenable and something that makes dogs howl. Export as MP3 at 320 kbps if you want it to sound decent on phone speakers. Lower bitrates introduce artifacts that become noticeable when the audio is already stretched thin by speed.

A problem I ran into and how I fixed it
Once, I exported a version at 200 percent tempo and it sounded fine in Audacity, but when I played it on my phone through Bluetooth speakers, the audio stuttered every four seconds. I spent about twenty minutes thinking the export was corrupted. It wasn't. The issue was that the Bluetooth codec on that particular phone was dropping packets at higher sample rates. I solved it by exporting at 44100 Hz instead of the default 48000 Hz, and the stuttering stopped completely. Something to keep in mind if you're testing on different devices. The biggest mistake I see is people applying a simple playback speed increase in a video editor like CapCut or iMovie instead of using a dedicated audio tool. Those apps often just resample the audio rather than using time-stretch algorithms. The result sounds like a degraded cassette tape played at high speed. It works for a quick TikTok, but it's not actually the same thing. Another thing: the original Hooda Math theme has a lot of silence at the beginning and end. If you speed up the whole file including those quiet sections, you get a brief burst of digital noise at each end that sounds like a pop or click. I usually trim two seconds off the start and end before applying the tempo change. Cuts the noise without affecting the actual content.
Limitations
This approach works fine for the Hooda Math theme because it's simple synth music with no vocals and minimal layering. If you tried the same process on a track with complex harmonics or spoken word, you'd get significant degradation. The SSMP algorithm in Audacity handles monophonic and lightly polyphonic material well, but anything with dense reverb or overlapping instruments starts sounding phasey and hollow at high tempo settings. For what it is, the Hooda Math theme survives the process cleanly. That's mostly because it was simple to begin with, not because the technique is universally reliable. If you need the fast version for a project and want higher quality than Audacity can deliver, Serato Sample or Ableton Live's Pro Mode time-stretch will give you cleaner results, but those cost money and have a steeper learning curve. For most people, Audacity is sufficient. The files circulate freely online, so there's no real barrier to getting one. If you want your own copy without relying on someone else's upload, the steps above will get you a clean result in about five minutes.
