Nightcore Maker

Turn any track into nightcore in your browser. Speed 1.25x to 1.40x with rising pitch, a bright tone lift and optional light reverb, then export an MP3.

Open the free editor: upload MP3, WAV, AAC, OGG or FLAC, adjust speed, reverb, bass, tone, width and space, then export MP3 or a ZIP of many tracks. Everything runs in your browser.

Nightcore is a song played fast enough that the vocal leaves the singer's natural register and becomes something brighter, higher and more urgent. The usual range is 1.25x to 1.40x with the pitch rising along with the speed, which puts the key 4 to 6 semitones above the original. Add a high-end lift, and sometimes a small amount of reverb to stop it sounding clinical, and that is the whole style. The editor above has the range and the controls for it, and the result is an MP3 you can keep.

Nothing is uploaded. The browser decodes your file, runs it through the speed, tone and reverb chain, and encodes the MP3 locally. If you are new to the genre, what is nightcore covers the history in more depth. If you want the subtler, chart-pop version of a fast edit, the sped up song maker is a better fit, and the differences are laid out below. For the general speed utility, including Preserve pitch for practice tracks, see speed up a song.

Where nightcore comes from

The name comes from a Norwegian duo who, in the early 2000s, sped up trance and eurodance tracks and released them under the name Nightcore. The sound spread through YouTube in the late 2000s, almost always paired with anime artwork, and became a fan genre of its own. The source material was and largely still is dance music: eurobeat, hands up, trance, J-pop, anime openings and endings, and later any pop song a fan happened to love.

That history explains the settings. Dance music already has a four-on-the-floor kick and a bright, synthetic top end. Speeding it up by 30% lands around 160 to 180 BPM, which is happy hardcore territory, and the vocal rising 4 to 5 semitones gives it the characteristic youthful, almost anime-voice quality. The style is not trying to sound like a plausible alternate release. It is a transformation, and it is proud of it.

Nightcore settings

Preserve pitch stays off for every row. Nightcore with the original key is just a fast song; the raised pitch is the genre.

The rock row has a lower Tone boost because distorted guitars already carry a lot of high-frequency energy and a big shelf boost makes them fizz. The trance row has a little more Width because the style benefits from a wide synth bed.

How to make nightcore

1. Pick a track that can take it. Dance, pop and anime music work best. Anything with a slow tempo and a deep male vocal is a harder sell, because a 75 BPM ballad at 1.35x is still only 101 BPM and the voice ends up in an odd middle place.
2. Drop the file onto the editor. MP3, WAV, AAC, OGG or FLAC. Several at once is fine.
3. Start at 1.30x. Press play and jump to the chorus. If the vocal sounds right but the tempo feels frantic, come down to 1.25x. If it feels like a mild sped up edit rather than nightcore, go to 1.35x.
4. Lift the Tone. +3 to +5 dB on the high shelf. This is what gives nightcore its glittery edge. The speed increase already brightens the track, so do not go past +6 unless the source is very dull.
5. Decide on reverb. Most nightcore is dry. A small amount, 5 to 10% with Space at 1.4 to 1.8 s, can glue a sparse mix together and soften the hardness that a tone boost adds. Keep it short. Long decays belong to slowed edits, not fast ones.
6. Check the bass. Speeding up moves the kick and bass up in pitch, so they can feel light. +1 or +2 dB usually fixes it. More than that and the low end fights the brightness.
7. Export. One MP3 per track, or select several tracks and get a ZIP.

Nightcore compared with sped up and daycore

Daycore is literally the opposite move, slowing the same kind of source without the room sound of slowed + reverb. The daycore maker page covers it, and slowed vs nightcore vs daycore compares all three in one place.

Common mistakes

• Going too fast. 1.45x and 1.50x are available but they tip most vocals into a novelty sound. The genre lives at 1.25x to 1.40x for a reason.
• Boosting tone on an already bright master. Modern pop is mastered loud and bright. If the hi-hats hurt, drop Tone to +2 or even 0 and let the speed increase do the brightening.
• Long reverb. A 4 s tail on a 170 BPM track smears every kick into the next one. If you use reverb at all, keep Space under 2 s.
• Low bitrate source. Speeding up a 128 kbps MP3 pushes its artifacts into the most audible part of the spectrum. Use a lossless file or a 320 kbps MP3.
• Ignoring the tempo. Multiply the BPM. A 140 BPM track at 1.35x is 189 BPM, which is a lot even for nightcore. Fast sources often want the lower end of the range.

Batches and presets

Nightcore channels upload in volume. Add every track, Select All Tracks, set your speed and tone once, and Download All for a ZIP. If a few tracks need a slower speed, select only those and adjust. Once you have a sound you like, Create preset saves it beside the built-in ones, stored in your browser on that device, no account.

About the export

Exports are MP3 at 96 kbps, 32 kHz, encoded in a web worker. That is tuned for speed inside a browser and is fine for YouTube and TikTok, where the platform re-encodes your upload. There is no WAV or FLAC export. For a release-quality nightcore remix, work from a WAV and finish in a DAW. Also note that a nightcore version is a derivative work: the original copyright stands, and platform matching usually identifies the sped up version and claims it for the rights holder.
