How to Make Sped-Up (and Slowed) Versions of Songs for TikTok

The sped-up edit took over TikTok years ago and shows no sign of leaving; half the sounds trending on any given week are somebody's song running 20 percent fast. If you want a sped up song maker that doesn't watermark the file or park you in an upload queue, SoundCraft, ClipCraft's free browser audio editor, ships one as a preset. It's literally called TikTok Sped-Up. Drop a song in, pick it, export an MP3. The processing happens on your own machine, so the song never uploads anywhere. It handles slowed edits too, with one catch I'll get to.

What a sped up song maker actually does

There are two ways to speed up audio. Modern software can stretch tempo while holding the pitch steady, which is what a DJ sync button does. The TikTok sound is the other one, the old tape way: resample the audio so it plays faster and every frequency rises with it. Speed a track up 20 percent and the vocal climbs about 3 semitones. That lift is the sound. It makes a moody song feel urgent and a pop vocal feel weightless, and it's the reason a pitch-corrected "fast version" sounds strangely flat next to a real sped-up edit.

SoundCraft's effect works the tape way on purpose. Pitch follows speed is locked on in the panel, so what you export is the same coupling every viral edit uses.

Sped-up vs nightcore: same trick, different dose

Nightcore is the same resampling idea pushed harder. A typical TikTok sped-up edit sits around +15 to +25 percent, fast enough to feel electric but slow enough that the singer still sounds like themselves. Nightcore starts around +30 percent and embraces the chipmunk. The effect in SoundCraft covers both; it's the Nightcore tile in the rack, and I wrote a separate guide to making actual nightcore with the Classic preset. This post stays in the gentler range, plus the slowed direction that nightcore never goes.

How to make a sped-up version of a song

1. Create a free account. The editor is free, the effect runs client-side, and there's no watermark on exports.
2. Open SoundCraft and pick a temporary session from the entry modal (fine for a one-off edit).
3. Drag your song onto a timeline lane. MP3 or WAV both work.
4. Click the ☰ button top-right and pick the Nightcore tile, last in the Audio effects tab. The control panel opens in the workspace below the timeline.
5. Set the Preset dropdown to TikTok Sped-Up.
6. Press play, nudge Speed if you want, then hit ⬇ Export.

Here's what the preset did to my test track, a 41-second loop at 120 BPM. The readout grid answers the two questions you actually have before posting: the loop became 0:34, and the tempo jumped from 120 to 144 BPM. Speed reads +20% / 1.20x, and the fine print under the pitch slider shows the vocal rose +3.2 semitones, all of it from the speed change.

Twenty percent is a good default, and the preset also adds 1 dB of brightness and half a dB of bass preserve, because resampling shoves a song's energy toward the treble and thins the low end. If the edit feels too aggressive, Soft Sped-Up drops the speed to +15 percent, which I'd use on anything slow or sad. Going the other way, the Speed slider runs to +60 percent, but past +25 you're making nightcore whether you meant to or not. Everything responds during playback, so leave the song looping and drag until it feels right. Touch any control and the preset dropdown flips to Manual, which is just the panel telling you the settings are yours now.

Making a slowed (and reverb) version instead

Slowed + reverb is the mirror-image trend: drop the song a couple of semitones, let it drag, drown it in space. SoundCraft does this in the same panel, but not with the control you'd guess. The Speed slider stops at 0; it won't go negative. The slowing lives in the Extra Pitch slider, which runs down to −12 semitones and is tape-style like everything else here, so pulling pitch down slows the song with it.

Set Speed to 0 and Extra Pitch to −2.0 st and you have the classic slowed sound. On my test loop the readout flipped to 0:41 → 0:45 and 120 → 107 BPM, roughly 11 percent slower. Push to −12 and the song plays at exactly half speed, which is deep into vaporwave territory.

For the reverb half, open the ☰ rack again and add the Reverb effect to the same channel. It sits after the speed change in the chain, so the tail smears the slowed version, which is the point. A long decay and a modest wet mix gets you the sound; the exact numbers are taste.

There's also a second route if you only want part of the song slowed: select the clip and use the Transpose stepper in the workspace's Clip tab. It shifts that one clip up or down 12 semitones, tape-style, independent of the effect, and it retunes the playing audio as you step it. SoundCraft is a full multitrack DAW underneath all this (here's the full tour), so a half-time switch-up mid-song is a split and two clips rather than a second project.

Export it, then make the video

The ⬇ Export dialog renders the mix with the speed change baked in and gives you lossless WAV or a 192 kbps MP3. The same dialog can post the finished track to the ClipCraft music feedif it's yours to share.

One more practical thing. A TikTok sound is usually 15 to 30 seconds, and you don't have to export the whole song to get one. The dialog has Track start and Track end fields measured in bars, and a Loop link checkbox that exports exactly the loop region you've highlighted on the timeline. Drag a selection across the hook, tick the box, and the MP3 that comes out is just that slice at the new speed. Trimming in SoundCraft beats trimming in TikTok's clip picker, because you choose the downbeat it starts on.

A TikTok sound still needs a video file. ClipCraft's Video Captions tool has an audio-to-video mode for exactly this: hand it the exported MP3, pick a frame size like 1080×1920, set a background color or image, and it renders a real video, with animated lyric captions if you want them. And if your plan was a sped-up acapella rather than the whole song, pull the vocal out first and run the effect on the stem.

Can you post a sped-up version of someone else's song?

The trend got big enough that labels now put out official sped-up versions, which tells you two things: the format sells, and rights holders are paying attention. An edit of someone else's recording is a derivative work, and publishing or monetizing it needs their permission; unofficial edits live on borrowed time and content ID. Your own music is a different story. Speed up your own songs, including AI-generated tracks from tools like Suno, and post them anywhere you want.

That's the whole workflow: one drop, one preset, one export, and the slowed version is the same panel with two sliders moved. Sign up free and try it on something you made. The editor costs nothing; paid plansonly add storage for saved projects and server compute you don't need for this.
