Daycore Maker

Make a daycore version of any song in your browser. Slow it to 0.75x to 0.88x with the pitch dropping, keep reverb low or off, and export an MP3 for free.

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.

Daycore is the mirror image of nightcore. Where nightcore speeds a song up and lets the pitch climb, daycore slows it down and lets the pitch fall, usually to somewhere between 0.75x and 0.88x. The name started as a joke, anti-nightcore for the daytime, and stuck. What separates daycore from the slowed + reverb style everyone knows is the room: daycore has little or no reverb. It is the slowed song itself, heavy and deep, without the cathedral behind it.

The editor on this page runs in your browser with nothing uploaded. Drop a file, set Speed below 1.00x, leave Reverb at or near zero, export an MP3. If you want the reverb-soaked version of a slowed track, the slowed reverb maker starts you at the Haze Chamber preset instead. If you want to slow a track down but keep it in key, the slow down song page covers Preserve pitch. And for the history and culture of the style, read what is daycore.

Daycore versus slowed + reverb

They share a speed range and they are both about slowing, so people conflate them. Side by side the difference is obvious.

Daycore keeps the vocal in the front of the mix. You hear every consonant, just lower and slower. Slowed + reverb pushes the vocal back into a room and lets the tail blur the words into the beat. One is a changed song. The other is a changed place.

Daycore settings

Preserve pitch is off in every row. The pitch drop is the point of daycore, just as the pitch rise is the point of nightcore. The Space column does not matter when Reverb is 0%, so the default 2.4 s is left in place.

The dance row runs slower than the pop rows because a 140 BPM eurobeat track at 0.78x lands at 109 BPM, which is a comfortable mid-tempo, while a 100 BPM pop song at 0.78x drags at 78 BPM.

How to make a daycore edit

1. Load the track. Drag an MP3, WAV, AAC, OGG or FLAC file onto the editor. Good sources matter here more than in slowed + reverb, because there is no reverb to hide artifacts behind.
2. Click Dry. This resets every control. Daycore is built up from nothing, not down from a wet preset.
3. Set Speed to 0.82x and press play. Listen to the vocal at the chorus. If it has gone gravelly, come up to 0.85x or 0.88x. If it still sounds like the original with a slight drag, go to 0.78x.
4. Add Bass sparingly. Slowing shifts energy down, so a track usually gets heavier on its own. Add +2 to +4 dB only if the kick has lost its punch.
5. Tone to taste. Daycore usually wants a neutral or very slightly dark top end, 0 to -3 dB. Dropping further starts to sound like a slowed + reverb edit with the reverb removed, which is not quite the same thing.
6. Reverb: leave it or barely touch it. If you add any, keep Reverb under 20% and Space under 2.0 s. The moment the tail is audible as a tail, you have made slowed + reverb.
7. Export. Download for an MP3, or select several tracks and download a ZIP.

Why daycore works on some songs and not others

Slowing a track by 20% lowers every frequency by about 4 semitones and stretches every transient. In a slowed + reverb edit the reverb glues the stretched pieces together. In daycore nothing glues them, so the song has to hold together on its own.

Songs that work: tracks with a strong, steady beat and a vocal that has room to go lower. Bright female vocals often sound best, because dropping them 3 or 4 semitones puts them in a warm alto range rather than a strained one. Dance and anime music, the same sources that nightcore uses, often work beautifully for exactly the same reason: they were built with a lot of energy, and daycore spends some of it.

Songs that struggle: slow ballads, which crawl; very low male vocals, which turn into a mumble; and busy mixes with a lot of detail, which turn into a smear without reverb to make the smear feel intentional.

A quick test is to audition at 0.82x for ten seconds at the chorus. If you want to keep listening, it is a daycore song.

Daycore and nightcore from the same file

One habit among anime music channels is to post both versions of a track. Add the file twice, or add it once, export at 0.80x, then change Speed to 1.30x with Tone at +4 dB and export again. The nightcore maker page has the full settings for the fast version. For a side-by-side explanation of all three styles, see slowed vs nightcore vs daycore.

Batch daycore

Add a whole album, Select All Tracks, set Speed to 0.82x and Bass to +3 dB, and Download All for a ZIP with every track processed the same way. Consistency across a batch matters more in daycore than in slowed + reverb, because without reverb a speed difference between two tracks is immediately audible. Save your settings as a custom preset with Create preset so the next album starts from the same place.

Export and copyright

The export is an MP3 at 96 kbps and 32 kHz, encoded inside your browser. That is fine for YouTube, TikTok and Shorts because they re-encode on upload. There is no WAV export, so for anything you intend to distribute, process a WAV in a DAW. A daycore version is a derivative work of the original recording. Platform matching recognises slowed versions, and the usual result is a claim by the rights holder, occasionally a block.
