Make a sped up version of a song
The edit that took over short-form video: a little faster, a little brighter, and suddenly the track fits a fifteen-second clip. One slider, two minutes, nothing installed.
The steps
- Load the track. An MP3 or WAV from your device, or a YouTube link.
- Start at 1.15×. Enough to feel intentional, not enough to draw attention to itself.
- Adjust between 1.10× and 1.25×. Slow, sung tracks take more; anything already fast takes less.
- Or hit the SPEED UP preset. It sets 1.22× with 12 % bass boost — the bass is not decoration, speeding a track up genuinely thins its low end.
- Export. MP3 to publish, WAV or FLAC if the file goes into a video editor.
Speeds, and what each one is for
| Speed | Reads as | Typical use |
|---|---|---|
| 1.05× – 1.10× | Barely noticeable | Tightening a track that drags |
| 1.15× | Clearly sped up | The safe default for short video |
| 1.22× (preset) | Punchy | The common social-media edit |
| 1.25× | The border | Past this, it starts to read as nightcore |
| 1.30× and up | Nightcore | See the nightcore converter |
Sped up, nightcore — where the line sits
With the classic method, raising the speed raises the pitch along with it, exactly as a record spun faster rises in pitch. That is true of the sped up edits you hear on social platforms, and it is what this tool does.
So the difference between sped up and nightcore is not the technique, it is the degree. Below about 1.25× the ear registers "same song, faster". Above it, the raised voice becomes the point of the edit, and the result belongs to nightcore. The nightcore guide goes further into where that style came from.
What it costs, plainly
Your own file is free. Unlimited, no account, processed by your browser on your machine — which is also why the audio never leaves your device.
A YouTube link is paid. That mode runs on a server, because the track has to be fetched and decoded. €2.99 for seven days, €19.99 for a year, paid once, with fifteen seconds of the result before you decide.
What it will not do
It will not raise the tempo while keeping the original pitch. Speed and pitch move together here, deliberately: that is how these edits are made. If you need the tempo changed with the voice untouched, look for a time-stretching tool instead — and expect artefacts, because that operation is far harder than it sounds.
It will not fix a track that is already fast. Above roughly 150 BPM, most songs lose their groove before they gain anything.
And it will not settle the rights question. A sped up version is a derivative work, and fingerprinting identifies it.
Frequently asked questions
How do you make a sped up version of a song?
Load it, raise the speed to 1.10× – 1.25×, add a little bass if it thins out, export. Nothing to install, and your own files are free.
What speed are sped up songs on TikTok?
Most sit between 1.15× and 1.25×. Beyond that, the pitch lift takes over and the edit reads as nightcore.
What is the difference between sped up and nightcore?
Degree, not method. Both raise speed and pitch together. Sped up stays moderate; nightcore pushes past 1.25× until the high vocal becomes the effect.
Can you speed up a song without changing the pitch?
Not here. Speed and pitch are tied together on purpose, the way a record spun faster rises in pitch. Tools that preserve pitch rebuild the audio and leave artefacts.
Is it free?
Yes for a file from your own device — unlimited, no account. Only the YouTube link mode is paid.
Can I publish it?
A sped up version is a derivative work. The rights on the original still apply and platforms identify it by fingerprint. For anything beyond private listening, check the source.
