Speed up a song. The sped-up sound, pitched up with it, or faster in the same key. Free, in your browser.

Updated

Files over 10:00 are trimmed to the first 10 minutes. For reverb and the Sped up and Nightcore presets, use Slowed + Reverb; for an exact BPM, the Tempo & BPM Changer; to go slower, Slow Down a Song.

How to speed up a song

  1. Step 1: Choose a song

    Drop in an MP3, WAV, M4A, FLAC or OGG, or a video's sound track. It opens at 125% speed with the pitch rising with it.

  2. Step 2: Pick how fast

    Use a preset (110%, 125%, 150%) or the slider, up to 200%. Leave "Pitch up with it (sped-up / nightcore sound)" on for the sped-up sound, or choose "Keep pitch" to stay in the same key, then press Apply.

  3. Step 3: Download

    Compare with the original, then save a WAV or a 192 kbps MP3.

How to make a sped-up version of a song

Drop the song in and press Apply: the page opens at 125% with "Pitch up with it (sped-up / nightcore sound)" selected, which is how sped-up songs are made. The track plays faster the way a record does when you turn the speed up, so the voice rises with it, +3.9 semitones at 125%. That brighter, younger-sounding vocal is the sped-up sound; push it to 150% and beyond for nightcore.

Before the faster audio is made, whatever the speed-up would push past the highest frequency the file can hold is filtered out, so cymbals and hi-hats don't fold back as hiss. At the presets the pitch rises by 1.7 semitones at 110%, 3.9 semitones at 125%, 7.0 semitones at 150%.

Faster in the same key

Choose "Keep pitch" and the song is time-stretched instead: faster, but in its original key. Use it to bring a song up to a DJ set's tempo, to rehearse at performance speed, or to shorten a voice note or a lecture. Within about 125% most music sounds natural; beyond that vocals start to sound phasey.

Limits

Up to 100 MB per file; the first 10 minutes are used. A sped-up edit of someone else's song is still their song: the speed change does not change who owns it, and platforms can still match it.

Questions

How do I make a sped-up version of a song?
Drop the song in, keep "Pitch up with it (sped-up / nightcore sound)" selected, choose a speed (110%, 125%, 150%, or anything up to 200%) and press Apply. Then download it as WAV or MP3.
What speed are sped-up songs?
Usually 120–130%, which raises the pitch by +3.2 semitones to +4.5 semitones. Nightcore edits often go further, toward 150%.
Can I speed it up without changing the pitch?
Yes: choose "Keep pitch". The song is time-stretched, so it is faster but in the same key.
How fast can it go?
Up to 200%, double speed, which raises the pitch a full octave when it follows the speed.
Is it free, and is my audio uploaded?
Free, with no sign-up and no daily limit. The file is processed inside your browser and never leaves your device.
Can I add reverb, or set an exact BPM?
For reverb, use the Slowed + Reverb generator, which also has Sped up and Nightcore presets. For an exact tempo, use the Tempo & BPM Changer.
