How to make a daycore edit in 3 steps
- 01
Open your track
Click Open file, drag a track into the drop zone, or select Try a demo to hear how the daycore maker slows and lowers a sample loop before you use your own audio.
- 02
Choose Classic or Independent, then add reverb
In Studio settings, choose Classic mode, which links speed and pitch, or Independent mode, which lets you set the pitch drop yourself. Drag speed from 50% to 100%, or start from the Classic daycore 75% preset, then dial in reverb mix and decay.
- 03
Preview, compare and export
Click Render preview and use Original/Processed to compare the daycore version against the source. Pick an output format and click Download audio, or Save preset first if you will reuse this combination.
What you can do with this daycore maker
- Classic mode links speed and pitch the way slowing down a record does, so pitch drops automatically as playback slows — the defining daycore sound.
- Independent mode slows the track while you set the pitch drop yourself, from 0 to −12 semitones, for a gentler or more extreme character than Classic mode gives you.
- Speed range from 50% to 100%, with the Classic daycore 75% preset as a reference point, alongside Deep and Dreamy presets for heavier or softer variations.
- Reverb mix from 0% to 80% with adjustable decay, layered onto the slowed track for the atmospheric tail daycore edits are known for.
- Render preview and an Original/Processed A/B toggle so you can compare the daycore version against your untouched track before exporting.
- Export to WAV, MP3, FLAC, OGG, Opus, M4A, or AIFF, at source, 44.1 kHz, or 48 kHz, in mono or stereo.
- Save a speed, pitch, and reverb combination as a preset, or hand the result to another tool with Continue in another tool, with no re-upload needed.
- Processing runs entirely on your device, so a personal recording or an unreleased track never leaves your browser.
What is a daycore maker?
A daycore maker slows a track down and lowers its pitch at the same time — the direct opposite of a nightcore maker, which speeds a track up and raises its pitch. People also search for this effect as nightcore reverse, anti nightcore, or slowed nightcore — all names for the same idea: run nightcore's linked speed-and-pitch trick backward. This tool runs the whole process in your browser: open a track, choose Classic or Independent mode, add reverb if you want one, and render a preview without uploading anything.
One thing daycore is not: reversing the audio. A reversed track plays backward, with the waveform flipped end to end, and it sounds completely different from a slowed, pitched-down version of the same song played forward — daycore still plays your song in the same order, start to finish, just slower and lower. If you actually want to play a track backward, that's reverse audio, a separate tool built for exactly that.
Classic vs. Independent daycore: the math behind the pitch drop
Classic mode links speed and pitch through varispeed, the same relationship a nightcore maker uses in reverse. Pitch shift in semitones equals 12 times the base-2 logarithm of the speed ratio: 12·log2(rate). At the Classic daycore 75% preset, that works out to roughly −4.98 semitones — nearly five semitones lower, which is a large part of what gives daycore its heavy, drawn-out character.
Independent mode breaks that link: it slows the track to your chosen speed, then applies a separate pitch drop you set yourself, from 0 down to −12 semitones. That's useful if 75% speed feels right but a near-five-semitone drop sounds too dramatic for a particular vocal — you can slow the track the same amount while dropping the pitch less.
Reverb and the daycore atmosphere
Slowing a track down naturally opens up space between notes and transients, and daycore edits typically lean into that with added reverb — wet mix up to 80% with adjustable decay. A light reverb setting keeps the track close to its slowed original; a heavier setting pushes it toward the dreamy, cavernous feel associated with the Deep and Dreamy presets.
Because reverb and speed interact, it's worth adjusting them together rather than maxing out reverb before you've settled on a speed. Render preview after each change so you're judging the finished balance, not just one control in isolation — a reverb tail that sounds right at 75% speed can feel overblown at 90%.
Daycore vs. nightcore reverse vs. slowed and reverb: which tool do you need?
"Nightcore reverse" is a common way people search for daycore, since it's the linked-pitch opposite of a nightcore maker rather than a literal reversal of the audio, and "anti nightcore" describes the same idea from a different angle. This tool covers that intent directly with Classic and Independent modes built specifically around the daycore aesthetic.
If you want a broader slowdown tool without the nightcore framing — one built around comparing different slowed styles, with a Keep pitch option as well as linked — try slowed and reverb maker instead. Both tools share the same underlying speed and reverb engine; this one is tuned specifically around the daycore aesthetic and its presets.
What to expect from a daycore edit
Dropping pitch this much changes vocal character noticeably — voices sound deeper and slower in a way that's part of the effect, not a defect to fix. Very low settings can occasionally make vocals sound muffled rather than moody, especially on already bass-heavy source tracks, so Independent mode's smaller pitch drop is worth trying if Classic 75% sounds murky on a particular song.
As with any pitch and speed change, quality depends on the source: a clean, well-mastered track holds detail better once slowed and reverb is added than a heavily compressed one, where added reverb can make existing artifacts more noticeable rather than less. There's no quality cap or watermark built into this tool itself — what you start with sets the ceiling on the render.
Where the daycore sound comes from
Daycore emerged directly as a response to nightcore: it takes the exact same linked speed-and-pitch idea but points it the other way, producing a slower, heavier, more melancholic version of a track instead of a faster, brighter one. It's sometimes described as sounding underwater or half-speed, which is a fair description of what a roughly 25% slowdown with dropped pitch does to a familiar song.
Because it works on virtually any source material, daycore edits span genres far beyond where the style started, and the reverb tail this tool adds is often what pushes a slowed track from merely "slower" into the atmospheric mood associated with daycore specifically — speed and pitch alone get you partway there, but the reverb tail does a lot of the emotional work.
Tips for a cleaner daycore edit
- Start from the Classic daycore 75% preset, then switch to Independent mode if the pitch drop feels heavier than you want at that speed.
- Add reverb after you've settled on a speed — judging reverb on top of a moving target makes it harder to hear what each control is doing.
- Try the Deep preset for a heavier, more drawn-out mood, or Dreamy for a softer, more atmospheric version of the same slowdown.
- If you actually want a track played backward rather than slowed and pitched down, use reverse audio instead — daycore does not reverse the waveform.
- Render preview and A/B against Original/Processed before committing — a few percent of speed makes a bigger difference at daycore speeds than you'd expect.
- Save preset once a speed, pitch, and reverb combination works, so you can apply the same daycore treatment across a playlist quickly.
Frequently asked questions
What is a daycore maker?
A daycore maker slows a track down and lowers its pitch, the opposite of a nightcore maker. This tool does it with Classic linked speed and pitch, or Independent mode where you set the pitch drop yourself, plus reverb for atmosphere.
Is daycore the same as reversing audio?
No. Daycore slows a track's playback and lowers its pitch, but the track still plays forward, start to end, in the same order. A reversed track plays backward with the waveform flipped; that's a different effect, available in reverse audio if that's what you actually want.
What speed is daycore?
There's no single fixed speed, but 75% is a common reference point and is the Classic daycore preset here. The range runs from 50% to 100%, so you can go heavier or lighter than the preset depending on the mood you're after.
Does daycore change the pitch, and by how much?
In Classic mode, yes — pitch drops together with speed. At 75% speed that's about −4.98 semitones, close to a full five semitones lower. In Independent mode you set the pitch drop yourself, from 0 to −12 semitones, at whatever speed you choose.
How do I make a daycore track?
Open a file or drop it onto the drop zone, choose Classic or Independent mode and a speed in Studio settings, add reverb if you want one, then click Render preview. Compare with Original/Processed and click Download audio when you're ready.
Is this daycore maker free?
Yes, free with no sign-up and no watermark on the export. All processing happens on your device, so there's no server queue, no account to create, and no upload wait, however many tracks you run through it.
Is my audio uploaded anywhere?
No. Everything runs locally in your browser using the audio engine built into your device. Your file is never sent to a server during speed, pitch, or reverb processing, whether it's a personal recording or a finished track.
What audio formats work for daycore?
Input covers anything your browser can decode, typically MP3, WAV, FLAC, OGG/Opus, M4A/AAC, AIFF and WebM. Export options are WAV, MP3, FLAC, OGG, Opus, M4A, and AIFF, with a choice of sample rate and channel count.
Is there a file size limit?
Files up to 150 MB are supported. Larger files may process more slowly, particularly on phones or older computers with less memory available, so a shorter clip usually renders more comfortably than a full-length album track.
Does this work on mobile?
Yes, in modern mobile browsers, though slowing and reverb processing together are more demanding than playback alone. Large files may run slower or use more memory than a desktop browser has to spare, so a shorter file processes more smoothly.
What's the difference between daycore and slowed and reverb?
Daycore always links pitch to speed for that lower, heavier character, with presets tuned to that aesthetic. Slowed and reverb maker covers a broader range, including a Keep pitch option, and is built for comparing different slowed styles rather than one specific mood.
What's the difference between daycore and nightcore reverse in the settings?
They're the same tool: nightcore reverse is just another name people use for daycore, since it runs nightcore's linked speed-and-pitch idea backward. There's no separate mode here — Classic and Independent cover both framings of the same effect.
Can I preview before I download?
Yes. Click Render preview after setting your speed, mode, and reverb, then use the Original/Processed A/B toggle to compare before you export anything or settle on a final output format and file type.
