Turn any song you have into nightcore: speed it up and raise the pitch together, add bass, preview live, and export. Free, with no upload.
The nightcore maker speeds a song up and raises its pitch at the same time. That linked shift is the whole sound: play a track about 25% faster without correcting the pitch and the vocal climbs roughly four semitones, the tempo jumps, and everything turns brighter and more urgent. Pick the Light, Classic, or Hyper preset or set the speed yourself from 105% to 150%, and add a low-shelf bass boost to put back some of the weight the upward shift takes out of the low end.
You hear every change live, and the export is rendered offline so the file matches the preview. It works on a file you already have, and your audio never leaves your device. If you want a song faster without the pitch going up, that is a different job — use the speed changer. For the opposite mood there's slowed + reverb, and how to make a nightcore song walks through the settings.
It raises the playback speed, and the pitch rises with it. At the Classic setting of 125% the song is a quarter faster and about 3.9 semitones higher, which is where the bright, energetic nightcore character comes from. Nothing is re-recorded or generated: it is your original audio played faster, with an optional low-shelf bass boost applied on top.
A plain speed-up, like the kind used for podcasts, keeps the pitch where it was and only shortens the track. Nightcore deliberately lets the pitch climb along with the tempo, so voices sound higher as well as faster. If you want the tempo change without the pitch change, use the speed changer instead.
Most nightcore edits sit between 120% and 130%, and 125% is the usual starting point. Lower settings around 115% keep vocals more natural, while 135% and above sound more extreme and can make lyrics hard to follow. Preview while you move the slider and stop when the vocal still sounds like the song.
Speeding a song up moves everything higher, including the bass, so a nightcore edit can sound thin. The optional bass boost is a low shelf at 120 Hz that puts some of that weight back. It starts at 0 and goes up to +9 dB; around +3 to +5 dB usually restores body at the Classic 125% setting. Go easy on loud masters, since a big boost can push the peaks into clipping.
For nightcore, use the nightcore maker. It plays the song faster, so tempo and pitch climb together in exact proportion, and it shows the resulting rise in semitones as you move the speed slider. The pitch changer is built to keep the two independent, which suits moving a song into a new key without changing its tempo. You can get close to nightcore there by raising both sliders, but its pitch moves in whole semitones, so the match is only approximate.
