1.25× is the classic nightcore rate. Unlike the Tempo Changer, the pitch rises with the speed — like spinning a record faster.

How it works
Nightcore Maker gives any song the nightcore treatment: faster and higher, together. The speed slider runs from 1.15× to 1.35×, with 1.25× as the classic rate — a 4-minute track becomes 3:12, pitched up about 3.9 semitones, brighter and more relentless.
Under the hood it is a two-stage render: a phase-vocoder time stretch sets the new tempo (pitch preserved), then a matching pitch shift raises every frequency by 12·log2(rate) semitones (duration preserved). The net effect is identical to speeding up tape — tempo and pitch locked together.
This is a buffer (offline) tool: the whole file is rendered with your chosen rate, then returned as a downloadable file. Everything runs client-side in your browser tab, so your files never leave your device and nothing is uploaded anywhere.
Frequently asked questions
What exactly is nightcore?
Nightcore is sped-up music where the pitch rises together with the tempo — the sound of a record spun faster. It started with sped-up trance in the 2000s and became a whole aesthetic: brighter, more energetic, a few semitones higher. This tool renders that exact effect at 1.15× to 1.35× speed.
How is this different from the Tempo Changer or Pitch Shifter?
The Tempo Changer speeds audio up while keeping the pitch the same, and the Pitch Shifter changes pitch while keeping the duration the same. Nightcore does neither in isolation: it speeds the audio up and raises the pitch by the same ratio, like tape. At 1.25× the song is 20% shorter and about 3.9 semitones higher.
Why does my song get shorter?
Because it is genuinely faster: at 1.25× speed a 4-minute song becomes 3:12. The pitch rise and the shorter duration are two sides of the same speed-up — you cannot have one without the other in true nightcore.
Is there a file size limit? Is it private?
Files up to 100MB are supported. The speed-up uses a phase-vocoder time stretch plus a pitch shift, which is CPU-heavy — long files take a little while. Everything runs in your browser; your audio never leaves your device.
