Nightcore vs daycore vs slowed + reverb

Six names, one basic idea: change the speed of a song. Here is what actually separates the styles, the settings behind each, and how to make every one of them.

The short version

StyleSpeedPitchSignature sound
Nightcore1.2–1.35×Up 3–5 semitonesFast, bright, energetic, high vocals
Sped up1.1–1.3×Up 2–4 semitonesPunchier, catchier, made for short clips
Daycore0.8–0.9×Down 2–4 semitonesSlower and deeper, lightly processed
Slowed + reverb0.8–0.85×Down 3–4 semitonesDreamy, spacious, nostalgic
Vaporwave0.65–0.8×Down 4–7 semitonesHazy, retro, tape-worn
Chopped & screwed0.6–0.75×Down 5–9 semitonesSyrupy hip-hop with repeated “chops”

The pitch column assumes the classic approach where pitch follows speed, like a turntable. The formula is simple: the pitch change in semitones is 12 × log₂(speed). So 1.25× raises a song about 3.9 semitones and 0.8× lowers it about 3.9.

Music: “Heart of Acceptance” by John Bartmann (CC0 1.0). Every version was made with this tool and volume-matched to the original. Switching keeps your place in the song.

Slowing down stretches every wave The same 6 cycles of a wave at normal speed and at 0.8 times speed. At 0.8 times the wave is 25% longer, so it sounds about 3.9 semitones lower. 1× original 0.8× 25% longer · −3.9 semitones
With Follows speed, slowing to 0.8× stretches every vibration, so the song is 25% longer and 3.9 semitones lower. Set separately uses time-stretching instead, which keeps the original pitch.

Nightcore

Nightcore is the oldest of these internet styles. It is usually traced to a Norwegian duo in the early 2000s who released sped-up trance and dance tracks under that name, and it grew on YouTube in the 2010s, where uploads were typically paired with anime-style artwork. The defining traits are a clear tempo jump of around 25% and the higher, brighter vocals that come with it.

Because everything gets brighter, nightcore edits can turn harsh. Trimming a little treble and keeping the limiter on helps. A short plate reverb adds polish without slowing the energy down. The nightcore maker starts at 1.25× with exactly that setup.

Sped up

“Sped up” is nightcore’s modern, less stylised cousin, popularised by TikTok, where a faster version of a chorus fits more hook into a short clip. Speeds are often a bit gentler, and some creators keep the original key by changing tempo only, which you can do with the “Set separately” pitch mode. The sped up song maker defaults to 1.2× with pitch following speed.

Daycore

Daycore was named as the opposite of nightcore: slow the song down instead of speeding it up. In practice it means 0.8–0.9× with the pitch dropping, often with only a light reverb, so the result stays close to the original mix, just heavier and calmer. Try the daycore maker.

Slowed + reverb

Slowed + reverb takes the daycore idea and makes space the main feature. Speeds of 0.80–0.85× lower the song into a more melancholy register, and a large, long reverb (a hall with a 3–4 second decay at 30–50% mix) makes it sound distant and dreamlike. It became one of the most recognisable sounds on YouTube and TikTok because it suits late-night listening and emotional songs so well. Our settings guide breaks the recipe down by genre and mood.

Vaporwave

Vaporwave is a full genre rather than just an edit style. It emerged online in the early 2010s, built from slowed, pitched-down and looped samples of 80s and 90s pop, smooth jazz and commercial music, with a deliberately nostalgic, slightly unsettling feel. To get the sound, go slower (around 0.7×), roll off the highs, and add tape wobble, vinyl crackle and warmth. The vaporwave generator combines all of them.

Chopped and screwed

Chopped and screwed came out of Houston in the early 1990s, pioneered by DJ Screw. “Screwed” refers to the heavy slowdown; “chopped” refers to the DJ cutting between two copies of the record to repeat words, stutter beats and create skips. It is a performance technique as much as an effect. The Screwed preset in the generator (0.7× with a heavy low end) gives you the slowed foundation; the chops are best done by hand in a DJ or audio editing app.

Which one should you make?

  • Want energy and hype? Nightcore or sped up.
  • Want a heavier, calmer take without much effect? Daycore.
  • Want atmosphere and emotion? Slowed + reverb.
  • Want a retro, hazy, internet-nostalgia feel? Vaporwave or lo-fi.

All of these are presets in the generator, so the quickest way to understand the differences is to load a song and click through them while it plays. Press “Original” at any point to hear how far you’ve moved from the source.

Frequently asked questions

Is daycore the same as slowed + reverb?

They overlap. Both slow the song and lower the pitch, but daycore usually keeps the reverb light and stays close to the original mix, while slowed + reverb leans on a big, washy reverb for atmosphere.

Is sped up the same as nightcore?

Close, but not quite. Nightcore traditionally means a fast, high-pitched version (around 1.25× or more) often paired with anime artwork. “Sped up” is the broader TikTok-era term and is often gentler, around 1.1–1.25×.

What is chopped and screwed?

A Houston hip-hop technique from the 1990s, pioneered by DJ Screw: the track is slowed heavily and “chopped” by repeating or skipping beats and phrases. The generator’s Screwed preset gives you the slowed half of that sound; the chopping is done by hand in a DJ or editing app.

Why does slowing a song make it lower?

Pitch is how fast a sound vibrates. Playing audio slower stretches every vibration, so all frequencies drop by the same ratio. At 0.85× they drop about 2.8 semitones. A time-stretching algorithm can avoid this, which is what “Set separately” does.

Which style is best for sad songs?

Slowed + reverb is the usual choice: 0.80–0.85× with a long hall reverb emphasises the melancholy. Daycore is subtler, and vaporwave adds a nostalgic, washed-out texture.
