Nightcore maker
The classic nightcore treatment: speed and pitch rise together. Set the intensity and render — 1.25× is the genre's sweet spot.

Nightcore is a speed-and-pitch edit, not a filter layered on top. Because the tool resamples the whole track at a faster rate, tempo climbs and pitch rises by the same ratio in a single pass — the same thing that happens when a 33 RPM record is played at 45. The style traces back to a Norwegian bootleg project in the early 2000s, and the sound has stayed recognizable since: brighter timbre, tighter groove, vocals nudged up a few semitones. There's no time-stretching involved, so you avoid the smeared, watery artifacts that separate pitch and tempo controls can introduce.
Most people reach for a nightcore maker to give an existing track more urgency, or to fit a song into the fast, high-energy pacing that short-form video rewards. Because everything runs locally in your browser, you can drag in a Suno export, audition a couple of intensities, and download the render without the file ever leaving your device. It's a quick way to test whether a track has a compelling up-tempo version before you commit to re-generating or re-recording it.
How it works
- 1
Drop the song.
- 2
Set the intensity (1.1×–1.4×).
- 3
Click render and download the nightcore version.
When to use it
- Speeding up a Suno-generated pop track to match the fast cutting pace of a TikTok or Reels edit, where a 1.25× lift reads as energetic without tipping into comedy.
- Producing a nightcore version of your own song for a YouTube AMV or lyric video, a genre-native format that anime and gaming channels have built audiences around.
- Auditioning whether a slow ballad works as an up-tempo cut before you regenerate the prompt in Suno, instead of re-rendering the whole song blind.
FAQ
What speed is "real" nightcore?
Most nightcore sits between 1.2× and 1.3× with pitch raised the same amount — the default 1.25× lands right in that range.
Can I speed up without the chipmunk pitch?
Yes — that's a different effect; use the audio speed changer, which keeps the original pitch.
Can I upload nightcore edits of other people's music?
Only with rights to the original. For your own generated tracks, you're fine.
Does nightcore change the key of my song?
Yes. Raising playback speed raises pitch by the same ratio, so the key transposes upward. At 1.25× the track shifts up roughly 3.9 semitones (close to a major third), and 1.5× lands about a perfect fifth higher. If you plan to layer the result against other instruments, account for the new key.
How much shorter does nightcore make a track?
It shortens by the speed multiplier, since you're playing the same audio faster. A 3:00 song at 1.25× runs about 2:24, and at 1.5× it drops to roughly 2:00. Worth checking if the edit has to hit a specific runtime for a video slot.
What's the difference between nightcore and 'daycore' or slowed + reverb?
They're opposites. Nightcore speeds up and pitches up; daycore (also called anti-nightcore) slows down and pitches down, and the popular 'slowed + reverb' style adds that lower, dragged-out feel with reverb on top. For the down-tempo version you'd set the speed below 1× rather than above it.
