Nightcore Maker – Make Nightcore and Daycore Songs Online

A full effects-rack music player with one-click Nightcore/Daycore presets and offline export.

This is a real-time effects player, not a batch converter: load a track and adjust bit-crushing, filtering, a synthesized reverb, stereo pan and playback speed while it's actually playing, hear every change instantly, and only render a file once the mix sounds the way you want. Seven one-click presets cover the classic sped-up nightcore sound, its slowed-down daycore counterpart, and five lo-fi degradation effects ported from an earlier project.

How to make a nightcore song

Drop a local MP3, OGG, M4A, FLAC, WAV, WebM or MP4 file into the player, or add several to the playlist, and press play.
Click the Nightcore preset for a 1.3x rate, or Daycore for 0.8x; either one also sets bit depth, filters, reverb and pan back to neutral.
While the song plays, fine-tune the 'Playback rate (pitch + speed)' slider (0.25x–4x) and open 'Advanced effects and quality' for reverb, filters, chorus or delay.
Pick WAV, FLAC, MP3, AAC (M4A) or Opus (Ogg) under Export and click 'Export mix' to render and download the result.

Nightcore vs daycore vs sped-up songs

Figures below assume a 3:30 song at 120 BPM. Pitch shift in semitones is 12 × log2(rate), because this player changes speed and pitch together.

Nightcore (1.3x): pitch rises about 4.5 semitones, the song shrinks to roughly 2:42, and 120 BPM becomes 156 BPM.
Daycore (0.8x): pitch drops about 3.9 semitones, the song stretches to about 4:23, and 120 BPM becomes 96 BPM.
Slowed + reverb: start from Daycore, then raise the Reverb wet slider for the washed-out sound.
Sped up with the original key kept: not possible here — that needs a pitch-preserving time-stretch, which this player doesn't have.

Why speeding it up also raises the pitch

The playback rate control changes the audio source node's own playbackRate parameter directly, the same mechanism a physical turntable or tape deck uses when you speed it up — it doesn't run a pitch-preserving time-stretch algorithm underneath. That's exactly why nightcore edits sound the way they do: pushing the rate up to the preset's 1.3x doesn't just play the track faster, it raises the pitch right along with it, and the daycore preset's 0.8x does the reverse. The control is clamped between 0.25x and 4x, so extreme settings are possible but the identity of the original recording gets harder to recognize the further you push it.

The degradation chain

A bit-crusher stage reduces effective bit depth from 4 up to 24 bits and can downsample by a factor of up to 64, with optional dithering — this runs on an AudioWorklet where the browser supports it, falling back to an older processing node otherwise. A highpass filter (up to 2000Hz) and a low-pass ceiling clamped to the track's own Nyquist frequency shape which frequencies survive; a reverb stage feeds the signal through a synthesized noise-based impulse response rather than a recording of an actual room, with its wet mix adjustable from fully dry to fully wet. Every one of these runs live, so you're always hearing the actual processed signal, not a preview approximation of it.

What the seven presets actually set

Broken Radio — narrow highpass, heavy downsampling and a low frequency ceiling for a crushed AM-radio character.
8-bit Handheld — aggressive 5-bit depth with light downsampling for a chiptune-adjacent texture.
Cassette Melt — near-full bit depth with dithering and a slightly slowed 0.98x rate for tape-warble character.
Underwater Club — heavy downsampling and a strong reverb wet mix with a low frequency ceiling.
Phone Line — narrow bandwidth and low bitrate feel for a classic telephone-call sound.
Nightcore — every degradation parameter left neutral, with only the 1.3x playback rate applied.
Daycore — the same neutral parameters, with a 0.8x playback rate instead.

Rendering and exporting a mix

Exporting doesn't just save the original file — it renders your entire live effect chain offline, sample by sample, into a fresh audio buffer that captures exactly what you were hearing, then encodes that buffer into WAV, FLAC, MP3, AAC or Ogg Opus using the same shared encoder every other audio tool on this site uses. Any title or artist tags the source file carried are read and carried into the export automatically.

Where the effect stops working

The reverb here is a synthesized effect, not a convolution against a real recorded space, so it will never sound identical to a proper impulse-response reverb plugin — treat it as a stylistic coloring, not a mixing tool. And because playback rate directly drives pitch, there's no way to speed a track up without changing its key using this player; if you need tempo change with pitch preserved, that's a fundamentally different algorithm this tool doesn't implement.

Saving a nightcore render is free 15 times per day, and unlimited with Pro.

Nightcore mixes are rendered in your browser

Playback, every effect and the offline render that produces your download run locally, so the song you load is never uploaded. The playlist remembers track names, durations and your effect settings in browser storage, but the audio itself isn't kept: after a reload you add the files again.

Questions people ask about Nightcore/Daycore Music FX Player

Why does the track sound higher-pitched after I apply the nightcore preset?: The nightcore preset works by increasing playback rate to 1.3x, and this player changes speed by directly adjusting the audio source's own playback rate — exactly like speeding up a record — rather than using a time-stretch algorithm that keeps pitch constant. The pitch rise is not a bug or a side effect; it's the actual mechanism the classic nightcore sound is built on.
Can I speed up a track without changing its pitch?: No, not with this tool. Every playback-rate change here directly drives pitch along with speed, since it's implemented as a raw playback-rate control rather than a pitch-preserving time-stretcher. You'd need a different, dedicated time-stretching tool for speed changes with pitch held constant.
Does the exported file include my effect settings, or just the original audio?: The export captures your entire live effect chain — bit-crushing, filtering, reverb, pan, and playback rate — by rendering it offline into a full audio buffer before encoding, so the downloaded file sounds exactly like what you heard while previewing it live in the player.
Is the reverb effect a real recorded room sound?: No — the reverb is generated from a synthesized noise-based impulse response rather than a convolution against a recording of an actual physical space. It gives a reverb-like character you can dial in with the wet mix control, but it won't replicate the specific sound of a real concert hall or studio room the way a sampled impulse response would.
What speed is nightcore?: There's no official standard speed for nightcore. This tool's Nightcore preset uses 1.3x, and the 'Playback rate (pitch + speed)' slider lets you pick anything from 0.25x to 4x in 0.01 steps if you want a subtler or more extreme version.
What's the difference between nightcore and sped-up songs?: Nightcore speeds the track up like a faster turntable, so the voice gets higher. 'Sped up' edits usually keep the original key with time-stretching. This player only does the first kind: any rate change moves pitch and tempo together, so it can make nightcore but not key-preserving sped-up versions.
Which file formats can I use?: The player accepts local MP3, OGG, M4A, FLAC, WAV, WebM and MP4 files; WebM and MP4 files are read for their audio. Mixes export as WAV, FLAC, MP3, AAC in an M4A file, or Opus in an Ogg file, with title and artist tags carried across where the format supports them.
Can I make nightcore from a Spotify or YouTube song?: Not directly. There's no link or URL field: the player works only on audio files already saved on your device, so a streaming track has to exist as a local file you're entitled to use before you can load it and apply the Nightcore preset.
Does my song get uploaded?: No. The file is decoded and played through the effects chain inside your browser, and 'Export mix' renders it offline on the same device. Only the playlist's track names and your slider settings are saved, in local browser storage — the audio stays wherever you loaded it from.
