How to make nightcore in 3 steps
- 1. Drop in a song (MP3, WAV, M4A, OGG or FLAC), or load the demo track to test the effect first.
- 2. Pick a preset or fine-tune the slider. 1.25x is the classic nightcore sweet spot; 1.2x is subtler and 1.35x is full send.
- 3. Hit Make It Nightcore, preview the result, and download it as MP3 or WAV.
What is nightcore, anyway?
The name comes from Nightcore, a Norwegian duo of two high school students who, around 2002, started releasing albums of trance and eurodance tracks sped up to roughly 125% as a school project. The formula — pitched-up vocals, racing tempo, pure energy — took on a life of its own. Through the late 2000s it spread across YouTube, where fan-made nightcore uploads with anime artwork thumbnails became a whole subculture tied to AMV (anime music video) editing. More recently the sound has cycled back into fashion on TikTok, where sped-up and nightcore versions of songs regularly outrun the originals.
Nightcore vs. plain sped up
They are cousins, not twins. A sped-up edit can be any small tempo bump; nightcore is a specific recipe: about 25% faster, with the pitch riding up alongside the speed so vocals land somewhere between "energetic" and "chipmunk" — that shift is the point, not a side effect. Nightcore also tends to sound brighter than a straight speed-up. To get that character, this nightcore generator adds a gentle 2 dB treble lift on top of the speed change, giving the top end that glassy sparkle you hear in classic edits.
Tips for edits that actually sound good
- Mid-tempo songs (roughly 100–128 BPM) take the jump best. A track that is already at 170 BPM turns to mush at 1.35x.
- If the vocals get too squeaky, back off to 1.2x. The effect should feel euphoric, not silly — unless silly is the goal.
- Start from the best source you have. Speeding audio up exposes the artifacts in low-bitrate MP3s, so a WAV or FLAC original gives a noticeably cleaner result.
- Ballads and emotional pop translate surprisingly well — the contrast between a sad lyric and a racing tempo is half of what makes the genre work.
FAQ
Is this nightcore maker free?
Yes. Every tool on SongToolbox is free with no sign-up, no watermarks and no export limits. Preview your edit and download it as MP3 or WAV.
Do my files get uploaded?
No. The whole thing runs in your browser using the Web Audio API. Your song is decoded, processed and re-encoded on your own device and never touches a server.
What speed is classic nightcore?
Around 1.25x, i.e. 25% faster than the original with the pitch raised along with it. 1.2x gives a lighter touch, and 1.3x to 1.35x is where the more extreme edits live.
Can I speed a song up without changing the pitch?
Not here — the pitch shift is what makes nightcore nightcore. If you want a tempo change that keeps the original key, that is a different effect (time-stretching) and a different sound.
What audio formats can I use?
MP3, WAV, M4A, OGG and FLAC files up to 60 MB and 15 minutes long. Downloads are available as 192 kbps MP3 or 16-bit WAV.
Can I post my nightcore edits online?
That depends on the rights to the original song. Edits of copyrighted music can be muted or taken down by platforms, so stick to music you own, have a license for, or that is royalty-free.
