How it works
Song in, edit out. Three steps:
1. Upload your track
Drop in a song you own or have permission to edit. Upload a common audio file like MP3 or WAV; the uploader shows size and length limits.
2. Pick a preset or drag the sliders
Start from sped up, nightcore, or slowed + reverb, then fine tune speed, pitch, and reverb until it hits.
3. Preview and download
Play it back instantly, nudge a slider, play again. When it sounds right, export it.
Sped up and nightcore: how fast is too fast?
A sped up song is the original track played faster, usually with the pitch rising too. That higher, brighter sound is the whole point. It is the version that loops on TikTok and makes a sad song feel oddly upbeat.
Nightcore is the turbo version: faster again, higher again, often with a heavier beat feel. Same idea, more energy.
- Light sped up: around 1.1x to 1.2x. Still sounds like the song, just with more bounce.
- Classic TikTok sped up: around 1.25x to 1.35x. Voices go bright and a little cartoony.
- Nightcore territory: around 1.4x and up. Big, fast, high pitched.
- Push speed up until it sounds right, then back off a touch.
Slowed and reverb
Slowed and reverb goes the other way. The song drops in speed and pitch, then a wash of reverb makes it sound like it is playing in a huge empty room. Moody, late night, perfect for study playlists and sad edits.
The trick is balance. Slow it a little, add a lot of space. Slow it a lot, keep the reverb tighter so the vocals do not turn to mush.
- Slowed: around 0.8x to 0.9x for the classic sound.
- Reverb: start mid, then push it until the vocal just starts to float.
- Reverb is adjustable, so add as much space as you like.
- Want a slowed version with no reverb at all? Set reverb to zero.
Pitch: lock it or let it ride
In a classic sped up or slowed edit, pitch moves with speed. That is the sound people expect. Sometimes you want only the tempo to change, like when a voice gets too squeaky.
Pitch moves with speed by default, which is the classic sped up sound. If you need exact BPM targets or a key change without the edit vibe, the pitch, BPM, and key tools are a better fit.
What people make with sped up edits
A sped up or slowed version is a whole mood switch. A few easy wins:
- TikTok and Reels sounds that match a fast cut edit
- Slowed + reverb playlists for studying, sleeping, or driving at night
- Nightcore versions of your own original songs
- Practice tracks: slow a section down to learn it by ear
- Alternate versions of a track you made, ready to post next to the original
Tips for edits that sound good, not broken
Small moves usually win. A few habits help:
- Start from the best quality file you have. Compressed files get crunchy fast.
- Change one slider at a time and listen after each move.
- Vocals show artifacts first. If they sound robotic, pull the speed back a notch.
- Reverb hides small glitches in slowed edits, but too much buries the words.
- Pick the best 15 to 30 seconds if the edit is for a short video.
Free, downloads, and your files
You can try the sped up song maker free. Free use comes with a free account, and plan details are on the pricing page. Downloads are audio files.
See the privacy policy for how uploads are stored. Speeding up or slowing down a song does not change who owns it. Only upload audio you own or have permission to edit, and check platform rules before you post an edit of someone else's track.

Who this is not for
This page makes sped up, nightcore, and slowed + reverb edits. It is not a precise tempo tool for DJs matching BPMs, and it is not a key finder. Use the pitch, BPM, and key tools for that. It is not a remixer that adds new drums or rearranges a song, and it does not give you rights to a song you do not own. If you need stem by stem time-stretching, a desktop DAW is still the right call.
