Change audio speed
for TikTok

115–130% up, 80–90% down — the two TikTok speeds

Almost every speed-changed sound on TikTok lives in one of two lanes. Sped-up versions sit between 115% and 130% of the original tempo. Slowed versions sit between 80% and 90%. Both lanes exist because of how this kind of speed change works: the pitch is linked to the tempo, so a faster song is also a higher song, and a slower song is also a deeper song.

That link is the whole sound. At 125%, a vocal rises about four semitones and gets that bright, eager quality that sped-up edits are known for. At 85%, the same vocal drops about three semitones and turns heavy and close. Go past the lanes — above roughly 140% or below roughly 75% — and voices stop reading as voices. The lanes are not rules, they are just where songs still sound like songs. Here is where the common settings land:

The tool on this page covers the full range, 50% to 200%, so you can hear both lanes on the same song and pick by ear instead of by habit. Drag the slider while the song plays — the change is live, so you hear each step as you pass it.

Which direction fits your edit

Speed is an emotional decision before it is a technical one. The same song carries a different feeling in each lane, and editors pick the lane to match the clip, not the other way around.

Sped-up suits energy: outfit transitions, montages, anything cut fast. The raised pitch makes a familiar chorus feel new, and the shorter runtime means more of the song fits inside a short clip — at 125%, thirty seconds of video covers 37.5 seconds of the original track. Slowed suits weight: text-over-sky posts, slow zooms, nostalgia edits. Most slowed sounds also carry reverb, which is why this tool has six rooms built in — Air, Room, Chamber, Hall, Plate and Cathedral, each with a mix control. For the slowed lane, try 85% with Hall and the mix around a third.

A loudness note before you export

TikTok adjusts playback loudness on its side, so there is no benefit in pushing your export as loud as possible — a squashed, distorted file stays squashed and distorted after the platform turns it down. What matters is headroom: if you add reverb, the wet signal stacks on top of the dry one, so pull the volume control down a little if the loudest parts start to crackle. A clean file at a sensible level survives every platform's processing.

Loop before you commit

Most TikTok sounds are built from one 15–30 second section, not the whole song. Use the loop control to ring-fence the chorus or the drop, then listen to it three or four times at your chosen speed. A setting that sounds right once can feel too fast on the third repeat — the loop tells you before your viewers do.

TikTok's own speed control is a different tool

TikTok has a playback speed button in its camera, and it is worth understanding why editors make their own file anyway. The in-app control changes the speed of the recording inside that one post — you do not get a file out of it, you cannot fine-tune by single percent steps, you cannot add a reverb room, and the sound exists only where TikTok put it. Making the sped up or slowed version here gives you an actual MP3 or WAV: you choose the exact setting, keep the file, reuse it across posts and platforms, and the audio under your video is precisely the one you approved with your own ears. For a throwaway clip the in-app button is fine; for a sound you care about, own the file.

From original song to TikTok-ready file

The whole job happens on this page, start to finish.

1. Drop an audio file onto the tool above, or pick one with the file button. MP3, WAV, M4A and the other common formats all work.
2. Pick your lane. Drag the tempo slider up into 115–130% for sped-up, or down into 80–90% for slowed. The pitch follows automatically.
3. If you went slow, open the reverb: choose a room, then set the mix so the effect sits behind the vocal instead of on top of it.
4. Set the loop around the section your edit will use and let it run a few times. Adjust by one or two percent if something feels off — small moves matter at these settings.
5. Export as MP3 or WAV. The export is free and covers the whole song. A short spoken note plays after the song ends, and because it comes after, you can crop it off in any editor — including TikTok's own trim.

Then upload the clip to TikTok as normal, or add the exported file over your footage in your editor of choice. Because the export is a plain audio file, it works everywhere — TikTok, CapCut, iMovie, Premiere, anything.

You love sped up and slowed songs? There is a player for that.

This page is a tool: you come with a file, you leave with a file. Y2K Player is the other thing — a music player for iPhone and iPad where every song in your library can live at its own speed.

The app saves each song's settings, so your slowed version of one track and your sped-up version of another are both just there the next time you press play. You get playlists, a real library, and it all works offline with no account. It also does what a browser cannot: export 1080p video over visualizers, ready to post. Free to use. Pro is one payment — forever.
