What Is Nightcore?

Nightcore explained: a sped up, pitched up remix style from early 2000s Norway and anime YouTube edits. Typical speed, pitch rise and how to make one.

Nightcore is a remix style in which an existing song is sped up, typically to between 1.25x and 1.40x of its original tempo, which raises its pitch by several semitones and gives it a bright, high-energy, almost frantic character. It started as the name of a Norwegian duo in the early 2000s who sped up eurodance and trance tracks, and became a whole genre of fan edit once YouTube uploaders paired the sound with anime artwork.

That covers the definition. Below is the fuller story: where the name came from, what the speed change does to the sound, how it differs from slowed and reverb and from its deliberate opposite, daycore, and how to make one in about a minute with the nightcore maker and its Lift preset.

Where nightcore came from

The name belongs to two students from northern Norway who, around 2002, produced a school project under the name Nightcore. They took existing eurodance, happy hardcore and trance tracks and sped them up, which pushed the vocals higher and the tempo faster than the dance floor originals. The project circulated on file sharing networks, and the name stuck to the technique rather than to the duo.

The second phase came on YouTube in the mid to late 2000s. Uploaders applied the same speed-up to pop, J-pop, rock and anything else, and put the result over a single anime illustration, often a character with large eyes and vivid hair. That visual became as much a part of the identity as the sound. For many listeners, nightcore means the artwork as much as the pitch.

Through the 2010s nightcore channels on YouTube reached very large audiences, and the style spread into dedicated communities, remix contests and eventually commercial releases that borrowed its sound. In the 2020s the lighter "sped up" trend on TikTok brought a cousin of nightcore to a much wider audience, usually at lower speeds and without the anime framing. The comparison of all these styles is on the slowed vs nightcore vs daycore page.

What speeding up does to a song

Nightcore is made with a simple playback rate change, the same way slowed + reverb is made in the other direction. The difference is the direction and the amount.

Three things change at once.

Tempo. A 128 BPM dance track at 1.30x runs at about 166 BPM, which is in happy hardcore territory. That is not a coincidence; the original Norwegian edits were turning dance music into something faster and harder.

Pitch. Unless pitch is preserved, the key rises with the speed. At 1.30x a vocal is roughly four and a half semitones higher. Male voices become high tenors, female voices become bright and youthful. That pitch rise is the thing most people mean when they say something "sounds nightcore".

Brightness. Shifting everything upward moves the energy toward the top of the spectrum. Hi-hats sparkle, synths become glassy, and bass gets thinner. Good nightcore edits usually add a little bass back and a touch of high shelf to lean into the brightness rather than fight it.

What nightcore is not

It is not just a faster song. Speeding up with pitch preserved gives you the original key at a faster tempo, which sounds like a rushed version of the same recording. Nightcore needs the pitch rise. If you want faster without higher, that is a practice tool, not a style; the preserve pitch page explains the option.

It is not reverb heavy. Where slowed + reverb lives on its room sound, nightcore is usually dry or close to it. A small amount of reverb can smooth the edges, but a large wash slows the perceived energy and works against the style.

It is not a genre in the production sense. Nightcore edits are made from existing recordings. Original tracks written to sound like nightcore exist and borrow its tempo and pitch, but the style is defined by the transformation.

How to make a nightcore edit

The free web editor on this site does this in a browser with no upload and no account.

1. Open the nightcore maker and drop in your file. MP3, WAV, AAC, OGG and FLAC all work.
2. Select the Lift preset. It sets speed to 1.30x, reverb to 0 percent, space to 2.2 seconds, bass to +1 dB, tone to +3 dB and width to 1.05. Those are the nightcore numbers. The Lift preset page explains each choice.
3. Adjust speed to taste between 1.25x and 1.40x. Lower for songs with already-high vocals, higher for low male vocals that have room to rise.
4. Leave Preserve pitch off. The pitch rise is the style.
5. Optional: add 5 to 15 percent reverb if the result sounds brittle. Keep space short, around 1.5 to 2.0 seconds.
6. Preview the chorus. If the vocal sounds thin, add 1 to 2 dB bass. If it sounds dull, raise tone a point.
7. Export. The MP3 is 96 kbps, 32 kHz, encoded in your browser, which suits YouTube, TikTok and Shorts because they re-encode anyway.

Which songs work

Nightcore flatters songs with strong melodic hooks, clear vocals and a dance or pop pulse. Eurodance, trance, J-pop, K-pop, pop punk and modern pop all take the speed well. Slow ballads can work, because speeding them up creates a mid-tempo song that did not exist before, but the lyrics can start to feel rushed.

Songs that already have very high vocals, dense rap verses or heavy sub bass are harder. High vocals turn shrill, fast rap becomes unintelligible, and sub bass thins out as it moves up. Audition for ten seconds at 1.30x before committing.

Nightcore and the sped up trend

The TikTok "sped up" sound of the 2020s is nightcore's quieter sibling. It typically runs between 1.10x and 1.25x, so the pitch rise is a semitone or three rather than five or six, and it dropped the anime visuals. Labels have released official sped up versions of singles in that range. If you want that sound rather than full nightcore, the sped up song maker page and the blog post on making a sped up version cover the lighter settings.

Copyright

A nightcore edit of a song you do not own is a derivative work. The pitch change does not hide it from platform matching; slowed and sped up versions are recognised. The usual result on YouTube is a claim with revenue to the rights holder, sometimes a block. Original or licensed music is the only route to monetising.

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.
