That is about +3.9 semitones of pitch and a 25% faster tempo.

What is the Nightcore Maker?

The ByteTools Nightcore Maker recreates the classic edit: play the song faster so the pitch rises with it, giving that bright, sped-up sound.

  • Speed and pitch slider from 115% to 135% with a live semitone readout
  • Optional tempo compensation for a pitch-up edit that keeps the original speed
  • Treble lift for the bright sheen the style is known for
  • Peak limiter on the output so the faster mix does not clip
  • Inline player and MP3 download
  • 100% local rendering - your music is never uploaded

About the Nightcore Maker

The ByteTools Nightcore Maker recreates the classic edit: play the song faster so the pitch rises with it, giving that bright, sped-up sound. A single slider from 115% to 135% controls the effect, and the page tells you how many semitones that works out to as you move it, so you can aim for a specific pitch rather than guessing.

It is the mirror image of a slowed and reverb edit. A checkbox restores the original tempo if you want the pitch lift without the speed-up, and an optional treble lift adds the airy sheen the style is known for. A peak limiter runs at the end so the result does not clip.

Everything is rendered locally by a WebAssembly build of ffmpeg. Your song is read from your device, processed in the tab and never uploaded. Remember that a nightcore edit is still a derivative of someone's recording, so check the licence before you publish one anywhere.

Frequently asked questions

What speed makes a proper nightcore edit?

Around 125%, which is roughly four semitones up. Below 120% the effect is subtle and above 130% vocals start sounding like chipmunks. The page shows the semitone equivalent as you move the slider so you can dial in a specific amount.

What is the difference between nightcore and sped up audio?

Nightcore raises the pitch and the tempo together, the way playing a record faster does, which is what gives it that bright vocal sound. Modern sped up edits often keep the original pitch. Tick the keep original tempo box here to get the opposite: pitch up with no speed change.

Does making a nightcore version reduce audio quality?

The file is decoded and re-encoded once, so there is a small generation loss, exported at a high LAME quality setting. What you will notice more is that raising the pitch shifts the top of the track upward, which can make cymbals and sibilance sound harsher.

Can I upload nightcore edits to YouTube or Spotify?

That depends entirely on the rights to the original song, not on this tool. A speed and pitch edit is a derivative work, so unless the track is yours or licensed for it, expect a copyright claim. Plenty of creators use royalty-free or original material instead.

How do I make the opposite, a slowed and reverb version?

Use the ByteTools slowed and reverb maker, which slows the track below its original speed and adds a reverb tail. It is the same technique in reverse, and both tools work the same way in your browser.
