Pitch & Tempo Changer — Shift Key and Speed Online

Raise or lower the key of a song in precise semitone steps, or change its speed without touching your DAW. Musicians use it to transpose backing tracks into a comfortable singing key, producers use it to create nightcore and daycore edits, and learners slow down fast passages to practice them note by note. Processing is instant because it happens on your device — nothing is uploaded, and the export is yours in one click.

How to use it

  1. Load your audio file into the Pitch & Tempo tool.
  2. Drag the pitch slider up or down in semitones to change the key.
  3. Adjust the tempo control to speed up or slow down playback.
  4. Preview the result in real time, then export the shifted version.

Frequently asked questions

Can I change pitch without changing speed?

Yes — the pitch and tempo controls are independent, so you can transpose a song's key while keeping its original tempo, or change speed while keeping pitch.

How do I make a nightcore edit?

Raise the pitch a few semitones and increase the tempo to around 120–130% — that bright, fast sound is the classic nightcore recipe. The reverse (lower and slower) gives you daycore.

What is a semitone?

A semitone is the smallest step in Western music — the distance between two adjacent piano keys. Shifting +2 semitones moves a song from C major to D major, for example.

Is this free and private?

Yes. Like every tool on this site, pitch shifting runs locally in your browser — free, no signup, and your audio is never uploaded.
